Marvel's Spider-Man: Webbed Champion

Marvel's Spider-Man: Webbed Champion (or simply Spider-Man: Webbed Champion) is Iago PUC’s second version of Marvel’s Spider-Man Season 2 airing of Disney XD, Disney Channel and Disney+. It follows the events of Season 1 and Season 2 episode: "School of Hard Knocks", and follows a new different storyline.

Premise
Still focusing on Peter Parker balancing his double life as a high school student and as the superhero Spider-Man, the season also focuses on Spider-Man’s new adventures with his friends following J. Jonah Jameson’s arrest. Along with episodes featuring Peter’s friends progressively becoming superheroes themselves after learning of his secret as Spider-Man, the season incorporates new episode arcs:
 * The City of Heroes arc, on which Peter’s friends progressively become new superheroes as they join Spider-Man’s battles against random threats in New York City, and they work to uncover the identity of the Master Planner, an enigmatic criminal with an unexplained grudge against Spider-Man.
 * The Family Business arc, on which Peter works on solving secrets about his family’s past while working to continue his late parents’ unfinished researches and scientific projects. A journey which leads him to a encounter with his long lost younger sister Teresa and the creation of new heroes who help him in his ordeals with supervillains.
 * The Legendary Universes arc, a special multi-part crossover arc on which Spider-Man and his friends travel across dimensions to uncover the origins of his parents' projects and prepare to face the Regent, who is longing to obtain discarded technology of Oscorp from other realities to establish a new, but more iron-fisted order in New York. Spider-Man's journey leads him to four universes from different franchises (promo refers to them as "universes beyond Marvel") where he makes new allies: those consisting of Rey Skywalker and her new Jedi Alliance from the Star Wars saga, Optimus Prime and the Autobots from the Transformers series, Sonic the Hedgehog and his fellow Freedom Fighters and the Teenage Mutant Ninja Turtles.

Events in the Crossover Universes

 * The story of the featured Star Wars universe is set after the events of Star Wars: The Rise of Skywalker, on which the Resistance has freed the galaxy from the First Order's tyranny, and Rey has started a new generation of Jedi with help from Jedi Masters from other dimensions and training young children who are also connected to the Force.
 * The story of the featured Sonic the Hedgehog universe has elements and characters from the 1995 animated series (which features the Freedom Fighters led by Sally Acorn), the Archie Comics (which introduces Hope Kinbotor), Sonic Boom (which introduced Sticks the Badger), and the 2020 film (which includes Sonic's human friend Tom Wachowski).
 * The story of the featured Transformers universe has elements of Michael Bay's cinematic franchise and the Prime TV series franchise.
 * The story of the featured Teenage Mutant Ninja Turtles has elements of the 2019 crossover animated film Batman vs. Teenage Mutant Ninja Turtles and the final season of the 2003 TV series.

She is an half-human, half Titanian Tiger hybrid (daughter of F.E.A.S.T. nurse Mary Watson and Titanian Tiger Soto (also known as Stark Industries scientist Dr. Phillip Watson)) who has the ability to shapeshift into a humanoid tigress with the abilities of Fire and Ice Breath, Hypnosis and (according to her teammates) the “strength of ten tigers combined” (provided by Superhuman Strength, wall climbing, Superhuman leaping, and able to run and swim in incredible speed). She is revealed to have known of Peter's secret life as Spider-Man since he was bitten by a radioactive spider (a flashback reveals she was the only one other than Peter himself at the Oscorp field trip who noticed the spider biting him) and has been in love with him after his first heroic success. She first made a non-speaking cameo in Season 1 episode "Venom", where she was the Football team mascot of Midtown High. She later made her full appearance in "On the Tiger's Claws", on which she is shown to have dropped out of Midtown High to enroll at Horizon High, and eventually revealing her metahuman and superhero nature.
 * Appearance: Her human form is that of a teenager with an auburn-red hair and blue eyes. Her Tigra persona has a bright red hair and green feline eyes and is based on Greer Grant’s variant in the original comics, but with the costume colored on blue with cat teeth in the belt and added with two golden bracelets and a small silver tiara with a tiger head-shaped sapphire.

 * Appearance: The same as in the original series' Season 2 episode "School of Hard Knocks".
 * Firestar / Screwball / Liz Allan (voiced by Natalie Lander) - One of Peter and Mary Jane's classmates at Midtown High School, where she is ranked class president.

In Season 2, she became Firestar, a superheroine with Flight and Pyrokinetic abilities, due to exposure to a small active shard of the destroyed Blood Gem which duplicated Molten Man's powers. She also sports a nanotech particle suit which adapts to her powers and changes her hair color from brown to red to further hide her identity. She also mentions herself as a fan of She-Hulk, whose costume was a main influence for Liz to forge her own.
 * Appearance: The same as in the original show. Her Firestar suit is a one piece leotard version of the one worn by Angelica Jones in the comics with the mask covering most of her head (leaving only her hair, eyes and mouth visible), and with her hair changing from brown to red and having a small fire in the tip.

She also wields a pair of Atlantean nano-tech esgrimas which can can extend themselves into a pair of Adamantium swords and (when fused together as a bo staff) can extend itself into a trident which can fire heat beams and electro-blasts.
 * Appearance: Based on her counterpart from Ultimate Marvel: Earth-2.
 * Ant-Girl / Cassandra "Cassie" Lang (voiced by Jessica DiCicco) - Gwen's rather enthusiastic, but highly intelligent 8-year-old younger cousin who received a prototype Pym Particle suit after coming in contact with a nano-tech wrist device which duplicated the functions of her father Scott's Ant-Man suit.

 * Stormranger / Teresa Parker (voiced by Mae Whitman) - Peter's long lost 12-year-old younger sister who was born eight months after her parents left Peter to the care of Uncle Ben and Aunt May. On the wake of her parents' death by the hands of the Red Skull, Teresa left the orphanage she grew up in and took up one of her father's secret projects, which includes technology resources from both Stark Industries and the Kree Empire. Soon after, she donned a new flight nanosuit (which includes the same functions of Tony Stark's Iron Man suit, as well as camouflage and phasing functions) with arm blades and optic beams and begun to operate as the new superheroine Stormranger in hopes of bringing Red Skull and his associates (including Norman Osborn) to final justice. While near to succeed, she crossed paths with Spider-Man, who revealed himself to her as her brother Peter and, after Red Skull's death and Norman Osborn's arrest, Teresa was given the courage to finally live a happy life with him and Aunt May. Although she still operates as Stormranger, Teresa also begun living the same lifestyle her brother does, including by enrolling as a student in Peter's former school in Midtown High.

The lion spirit is recognized by T'Challa / Black Panther as a spawn of the Egyptian wargod . In his off time, Marcus is a party entertainer who brings joy to children in orphanages and hospitals dressed as a cartoon lion called "Lyle the Happy Lion", impressing his high school crush-later-girlfriend Barbara Morse and clashing with the interests of his estranged older brother Flash Thompson, whom Marcus only prefers to address to by his real name Eugene.
 * Appearance: Visually a red-haired, green-eyed teenager. His Lion King armor is a lion-themed light brown variant of Black Panther's outfit in Ultimate Avengers 2 with a red mane.

 * Mantis (voiced by Hynden Walch) - A naive but innocent, genetically engineered alien girl with the abilities of Empathy, Astral Projection, Superhuman Leaping, Healing Factor and Plant Manipulation. Her consciousness initially inhabited the form of an mutated alien insectoid which Peter Parker's parents were experimenting on before being awakened by Peter, who developed a symbiotic, telepathic link with her. Later, she developed a more humanoid form by merging with a human clone body created by Viper to be part of Hydra's new clone army. After helping defeat Hydra, Green Goblin and Madame Masque, Mantis resumed to live in the jungle, although she would still come back to her master, since she is still linked to him. It is revealed in the "Legendary Universes" arc that the chemical substance which gave Mantis life is a sample of the Mutagen Ooze, the substance which created the Teenage Mutant Ninja Turtles and their teacher and adoptive father Master Splinter.
 * Appearance: Initially, a dark green insectoid with light green eyes, the body of a scarab, the head of a ladybug and mantis antennas. In her full form, she is visually a teenaged variant of Pom Klementieff's character in Guardians of the Galaxy Vol. 2 and Avengers: Infinity War, but with Medusa's eye design in Avengers: Black Panther's Quest and pointed, elven ears. She wears a barefoot two-piece dark green leotard, a leaf-made wristlet in her left arm and a blue flower in her hair.

It is revealed in the "Legendary Universes" arc that he is a AC astromech droid unit from the Jedi Order's dimension.
 * Appearance: Visually a blue sphere-shaped robot with white stripes, two plane wings, a camera lens in the left side of the forehead and a black screen with blue LED eyes.
 * Jarvis / J.A.R.V.I.S. (voiced by Patton Oswalt) - Richard Parker's old A.I. robot assistant who was stored in the main computers of the Triskelion before Richard and Mary were ambushed and killed by Red Skull. He was soon found and reawakened by his master's son Peter, who then downloaded Jarvis into the brain of a robot body which was part of the Parkers' second project. The robot uses the Tesseract (a cosmic-powered cube housing the Space Infinity Stone) as a power source and enhancer and has the functions of analysing and identifying organic individuals (able to scan humans' identities and personal profiles) and create teleportation portals. It is revealed in the "Legendary Universes" arc that Jarvis' robot body was an discarded E-100 robot unit created by Dr. Robotnik.
 * Appearance: His robot form is visually based on E-102 Gamma in Sonic Adventure and Sonic X, but colored on white and blue with logos of the Avengers in the shoulders and with the head resembling Iron Man's helmet.
 * Arsenal / Chris Cooper (voiced by Christopher Daniel Barnes) - An army sergeant who was assumed killed by the Red Skull while leading his men to an assault on Hydra. Flashbacks reveal that he was vaporized by Red Skull with a Neuro-Cortex-powered gun which not only disintegrated his body, but absorbed his consciousness into a micro-card which ended up lost when Truman Marsh double-crossed Skull and Osborn for his own plans. The card with his consciousness was later recovered by Teresa Parker / Stormranger, who then delivered it to Spider-Man and his team and transferred Sergeant Cooper's consciousness into an alien robot body which Peter and Teresa's parents were working on as part of their third project. Now named "Arsenal", Sergeant Cooper earned the abilities to manipulate technology and change his body to the form of any vehicle he scans. He eventually took the shape of one of the Avengers' Quinjets. He now acts as a guardian to Spider-Man and his friends, including his daughter Carlie. It is revealed in the "Legendary Universes" arc that Sergeant Cooper's Arsenal body was made of the remains of an Cybertronian Seeker who was not affiliated to either Autobots or Decepticons.
 * Appearance: His human form (seen in flashbacks and holograms) is based on actor Bradley Cooper's interpretation of Chris Kyle in American Sniper. His robot form resembles Jetfire in Transformers: Fall of Cybertron, but with a red helmet resembling Ultra Magnus' in Transformers: Prime and rocket turbines in his back.

She is shown to have a strong grudge with Otto Octavius, whom she blames for a lab accident which paralyzed her from the waist down and made her dependent of her wheelchair one year before Peter first became Spider-Man. She is also an ally of Spider-Man's team code-named the Alpha Owl, a high-tech wizard who monitors superheroes' activities through her computers (a role similar to Barbara Gordon / Oracle in DC Comics), and also enrolls as a student in Horizon High, where she earns a new advanced wheelchair with anti-gravity functions.

Harry eventually discovered best friend's secret identity during the "Spider Island" arc, putting his friendship with Peter at risk as he still blamed Spider-Man for his misfortunes. In Season 1's finale "Hobgoblin", Harry received the Hobgoblin technology from Norman and saved Peter from Octavius's mind control before ultimately saving his friend after seeing Norman's true colors. After his father's presumed death, Harry is Oscorp's acting CEO. After a long absence, Harry eventually returns in "Sons of Fathers", on which he helps Peter stop Donald Menken from selling Oscorp technology to Hydra, although Harry ends up feeling traumatized to hear of his father's shocking role in the deaths of his best friend's parents and Norman's alliance with the Red Skull.

After using the machine to put Octavius in a coma, Carolyn discarded her tentacles as a sign of refusing to throw away her second chance. Unfortunately, it is later revealed in "Brainstorm" that Carolyn's actions inadvertently resulted in Octavius' consciousness being trapped in cyberspace. Later in "Real Wild Initiation", motivated by Spider-Man's latest actions resulting in Octavius being incarcerated on a mental hospital and Norman Osborn getting arrested, Carolyn felt encouraged to don the Lady Octopus once again to redeem herself from her crimes, eventually becoming an official ally to Spider-Man and the Champions.

Cheerful and optimistic, she is shown to have a good relationship with superheroes, such as Spider-Man. She was first mentioned in "City of Heroes, Part 2: Where There's Smoke" by Liz Allan, who idolizes She-Hulk and states to have modeled her Firestar suit after She-Hulk's purple leotard. She makes her first official appearance in "The Parker Errand", on which she and her fellow attorneys are building a case against J. Jonah Jameson during his trial, leading her to team up with Mockingbird (and later Spider-Man and Venom) in seeking evidences to prolong Jameson's prison sentence.

Later on, she was shown residing in Pegasus Z (a dimensional island discovered by the Titanian Tigers where homeless metahumans can reside freely without persecution) with Nocturnal as her guardian. Kit also has a passion for chess (which her father was a great expert at).

Later on in "City of Heroes, Part 4: More Than Human", Nocturnal is shown acting as a superhero while explaining he had lost his fear of being seeing by the others following J. Jonah Jameson's arrest in "On the Tiger's Claws".

In Season 1's "The Rise of Doc Ock" arc, an accident by Crimson Dynamo caused his harness with tentacle-like appendages to be fused to his body, and he adopted the Doctor Octopus alias and turned the Osborn Commandos into the Sinister Five. His plans were foiled by Spider-Man and Hobgoblin in Season 1's finale "Hobgoblin". In Season 2 episode "Between Ock and a Hard Place", Octavius' body fell into a coma and his consciousness ended up in cyberspace to remain alive before relocating himself into the Living Brain. His plan to relocate himself into Spider-Man's body eventually backfired when Spider-Man's armor optics (powered by Vibranium provided by Black Panther) absorbed Octavius' consciousness and returned him back to his inactive body. From there, Octavius (while incarcerated back to the Cellar) attempted (but failed) to remember the codifications of the Neuro-Cortex and be rid of his memories from the past.

Although he was initially presumed dead following the "Rise of Doc Ock" arc, he resurfaced as the Spider King of the Jackal's Man-Spider army during the "Spider-Island" arc. In Season 1's finale "Hobgoblin", Norman utilized a replica Hobgoblin armor he made for his son so he can end Spider-Man himself, but was ultimately betrayed by Harry and is presumed dead following an explosion. He is revealed in Season 2 to have survived and gone into hiding with some of the technology he kept for himself from Oscorp. It is also revealed that he played a role in the deaths of Peter Parker's parents by turning them over to the Red Skull in retaliation of the couple having not agreed to work for him at Oscorp, inadvertently leaving Peter and his sister Teresa as orphans. Later reappearing in "Seeds of Life" as the Green Goblin, Osborn allied himself with Red Skull and his Hydra forces once more by working on human cloning using the cloning research he collected from Jackal. He was eventually defeated by Spider-Man and Stormranger, who teleported him back to New York.

During the "City of Heroes" arc, his arrest soon inspired other young heroes to act freely in New York while also exposed the Wake Riders (whom Jameson wrongly pointed as heroes) as true villains and accomplices of the Vulture and the Shadow Council. He is no longer seen again until "The Parker Errand", where it was revealed that Jameson also played a role in Richard and Mary Parker's death by Red Skull's hands by covering the truth about their demise as a "tragic, unexplainable accident", until Spider-Man, Mockingbird and She-Hulk sought evidences from Truman Marsh which led Jameson to be sentenced for life imprisonment.

Main Episodes
While the first five episodes remain the same as in the original Season 2 plot, the story goes on with a new different storyline:

06) “On the Tiger’s Claws”
As Peter Parker enjoys a date with his girlfriend Mary Jane Watson (who had dropped out of Midtown High to enroll at Horizon High following a conflict between Flash Thompson and one of the football jocks), J. Jonah Jameson (ambitious for knowledge of how Peter obtains so much good pictures of Spider-Man) hires Scorpion to intercept Peter and interrogate him. His plans, however, are put in jeopardy when Eddie Brock (angry and upset over being recently fired from the Daily Bugle) is pushed to his breaking point, forcing him to get pictures for the V-252 at the Space Administration, leading him to be transformed into a new version of Venom. Having predicted the issuing chaos to happen, Spider-Man and Mary Jane (who happens to be the half-human, half-alien werecat Tigra) work on defeating the two villains while Amon and Jade (two young Skrull scouts disguised as the couple in General Talos’ behalf) gather the evidences of Jameson’s crimes to expose him.
 * Note: It is revealed in this episode that all of Peter’s friends (from both Midtown High and Horizon High) are now aware of his secret as Spider-Man.
 * Outcomes: J. Jonah Jameson, exposed for hiring Scorpion to chase both Peter Parker and Spider-Man, is removed from the Daily Bugle and arrested for life. Eddie Brock is taken in to be punished by the Titanian Tiger tribe, and the V-252 is confiscated by the Skrulls to be lobotomized and stripped off its link from Peter. Meanwhile, Anya Corazon finds herself crawling walls like Spider-Man does, discovering in joy that she still has her spider powers from the Man-Spider incident.

07) “City of Heroes, Part 1: Spider-Gwen Returns”
Following J. Jonah Jameson’s arrest after the defeats of Scorpion and Venom, Peter is with Gwen Stacy overseeing a relic called the Blood Gem, which is said to contain mystical energies, after it was delivered to Horizon High after being found at an ancient dig site. Just then, the school is attacked by Electro, who is out to steal the Blood Gem on Silvermane’s behalf. During the chaos, Gwen exposes herself to the Blood Gem’s energies, which reawaken her dormant spider-powers, leading her to adopt the alias of Ghost-Spider as she and Spider-Man work to stop Electro and Silvermane from obtaining the Blood Gem. During which, Anya Corazon (having discovered that she still has her spider-powers from the Man-Spider incident) uses them to become Spider-Girl, as she and Miles Morales / Kid Arachnid work together in taking down Hydra spy Yelena Belova the Crimson Widow, who was sent by Arnim Zola to obtain the Blood Gem by any means necessary.

08) “City of Heroes, Part 2: Where There’s Smoke”
Caught by the radiations of a prototype Blood Gem after surviving an attack by Molten Man, Liz Allan earns the abilities to fly and manipulate and generate fire. Initially terrified of her mutation, Liz is still inspired by Spider-Man into becoming a new superheroine herself on the name of Firestar. As Spider-Man and Firestar work together to stop Mysterio from obtaining Oscorp technology to take over its newly developed drone units, Kingpin has his henchmen hunt for Screwball after she pulls a prank on his henchmen which costs him their researches for the Neuro-Cortex as she prepares for "the Ultimate Prank before her retirement". Little are both Kingpin and Mysterio expecting, however, a incredible surprise Spider-Man, Firestar and Screwball have been preparing for the two villains.
 * Note: It is revealed in the end that Screwball is still Liz wearing her suit above her Firestar outfit as part of her "Ultimate Prank".

09) “City of Heroes, Part 3: American Cats”
Spider-Man, Tigra and Kid Arachnid work alongside Kevin Hunt / American Knight and T’Challa / Black Panther to apprehend Vulture, who carries information about Killmonger and his plans with the Shadow Council. During which, they also cross paths with Flash Thompson's estranged younger brother Marcus (the feline vigilante known as the Lion King), who is out to stop Jack O'Lantern from getting revenge on Flash by targeting the students of Midtown High School. Things get harder when Killmonger sends Vulture after Jack O'Lantern and brainwash him as a member of the Shadow Council.
 * Outcome: Spider-Man is given by Black Panther a Vibranium particle enhancer which upgrades his web-suit, giving it a new look which now resembles the suit worn by Tom Holland's character in Captain America: Civil War and Spider-Man: Homecoming.

10) “City of Heroes, Part 4: More Than Human”
After overhearing the story of the peace treaty between Mutants and Inhumans, Spider-Man is informed of the existence of Kit Renner the Werefox, an orphaned child girl who happens to be a Mutant/Inhuman hybrid, and seeks to protect her by any means to preserve the peace treaty. He earns help from young Inhumans Ms. Marvel and Inferno and X-Men members Iceman and Rogue when it comes to protect Kit from Maximus the Mad and Magneto; both seeking to terminate Kit out of their protest of the peace treaty between their both kinds, and former military colonel-turned-fugitive William Stryker, who seeks to use Kit as a weapon against Mutants and Inhumans using new tech devices provided for him by the Master Planner.
 * Note: Ms. Marvel is revealed in this episode to be a trainee of the Avengers, not officially a member.
 * Outcome: Following Stryker's defeat by Spider-Man's hands, Spider-Man is honored for preservation of Mutant and Inhuman rights.

11) “City of Heroes, Part 5: Spider in the Eagle’s Shadow”
When Mister Negative and his Inner Demons arrive in New York seeking to take over the Ten Rings, forbidden relics which will unleash the Mandarin if in wrong hands, Spider-Man teams up with Lin Lie the Sword Master, Amadeus Cho / Brawn ant the Avengers (Captain America, Black Widow, Iron Man, and Hawkeye) to stop them. Meanwhile, Gwen, Miles, Anya and Kevin, all wanting to learn Spider-Man’s recently seen movements on Martial Arts following his fight against Chameleon, seek out his secret combat teacher Shang-Chi, who teaches the four more about the ancient arts of Kung Fu. During which, Spider-Man finds himself closer to figure out the identity of the mysterious Master Planner after the villain hires Taskmaster and his mercenaries to obtain the Ten Rings before both the heroes and Mister Negative do.
 * Note: The title of the episode is a reference to Snake in the Eagle's Shadow, a 1978 Hong Kong martial arts action comedy film directed by Yuen Woo-ping in his directorial debut, and starring Jackie Chan.

12) “Brainstorm”
As his friends (joined by Sam Alexander / Nova) resume to protect the citizens of New York and stop the recent riots in the city's criminal underworld, Spider-Man is called by Yuri Watanabe to help solve a mystery in the Supervillain Holding Facility, where both guards and inmates have gone berserk and are fighting each other until the facility collapses. Spider-Man finds out that the consciousness of Otto Octavius (the mastermind behind the recent chaos only identified to as the "Master Planner") has inhabited the body of the Living Brain, a robot made from the Neuro Cortex technology in the facility, and using the energy-focal device he made at Oscorp to begin making his enemies suffer. Octavius believes himself more than just prepared to fulfill his ultimate goal, but Spider-Man (who had predicted Octavius’ plans thanks to his lessons with Shang-Chi) still has a surprise element which Octavius was not prepared for.
 * Outcomes: Despite close to succeed, Otto Octavius' plan to swap bodies with Spider-Man backfires when Spider-Man (whose suit is shielded by a Vibranium particle enhancer provided for him by Black Panther which protects his brain from even the most powerful psychic attacks) redirects the Neuro-Cortex into the Living Brain and transports Octavius' consciousness into the energy-focal device. Later after returning Octavius back to his inactive body and delivering the Neuro-Cortex resources to his friend and new Horizon High classmate Carlie Cooper, Peter begins experiencing brief visions of his past, including one with his parents Richard and Mary Parker, on which he decides that his true work has just begun.

13) “What Girls Are Made Of”
While babysitting Gwen's little cousin Cassie Lang, Carlie Cooper tells her three stories about the amazing team ups between the super-heroines who fought alongside Spider-Man, which surprisingly happen at the same time outside of where they are. This episode features an anthology format split between three different segments:
 * 1) “Elements of Surprise” - Liz Allan / Firestar teams up with her best friend Michelle Jones, the Water-bending superheroine Wave, to stop a new group of criminals organized by Sandgirl in a warehouse of Oscorp.
 * 2) “Feline Pryde” - Mary Jane Watson / Tigra and her Mutant cousin Kitty Pryde / Shadowcat chase after Mystique, who has infiltrated A.I.M. as a double agent for Magneto to steal resources for the creation of new Sentinels.
 * 3) “Web of Shadows” - Ghost-Spider and Spider-Girl team up with Silk, an Inhuman with spider powers, to stop Madame Hydra, who had just ingested a serum based on Raymond Warren's Jackal formula and became the monstrous Viper and plans to collect the Jackal's mind-control researches, which she plans to use against Inhumans.
 * Note: Because this episode features female-centered storylines, it is therefore the only episode where Peter Parker / Spider-Man does not physically appear, despite being mentioned.

14) “The Parker Errand” (1)
After defeating the Living Brain and returning Otto Octavius’ consciousness back to his inactive body, Peter (having experienced surprising visions after his last exposure to the Neuro-Cortex) begins to solve secrets about his family’s past and find answers about what happened after his parents Richard and Mary Parker were killed by the Red Skull. His quest leads him to Gwen's grandfather Doctor Henry Pym, with whom Peter’s parents previously worked on secret projects of which the Red Skull and his followers have been unaware of. As Peter searches for these projects’ files and works alongside Mockingbird and She-Hulk to intercept Truman Marsh, who carries evidence of J. Jonah Jameson's past role in the Parkers' tragedy, and his A.I.M. units and stop them from obtaining the Tesseract (a alien relic containing the Space Infinity Stone) and use it to gain access to and invade Pegasus Z under their new leader MODOK's orders, Eddie Brock resurfaces with Venom bonded to him once again and, after experiencing memories of Peter's life (which include Peter's former teacher in Midtown High and Brock's lover Anne Weying) which sway them into being heroes, the two decide to stop A.I.M. in their own after discovering that Carlton Drake (the man who ruined Brock's life in San Francisco and ordered his employees to bring the Symbiote from its planet to Earth) also has ties with Marsh and MODOK.
 * Note: The plot is set during the events of previous episode.

15) “An Eye in the Sky” (2)
Now in possession of the Parker Projects' files and having decided to finish what his parents started, Peter begins to continue their unfinished projects, starting with AC-5 (or "Ace" as Gwen calls him), a very special drone powered by crystals of unknown origins. His work draws the attention of Inhuman king Black Bolt and his queen Medusa, who are familiar with the Parker Projects and offer to help Peter in exchange of his help with their ordeals with Ronan the Accuser, who seeks to collect a formidable relic from a Inhuman city to begin the Inhumans' extinction. Peter (as Spider-Man) eventually accepts their offer after learning that Ronan is also using Doctor Octopus' technology as a beacon for the Kree Empire to reach Inhumans on Earth and works alongside Silk, Inferno and bonded couple Cloak and Dagger to defeat Ronan and MODOK, who seeks the Kree Empire's technology to fully recover from his previous defeat. Meanwhile, a recovered Otto Octavius (incarcerated in the Supervillain Holding Facility) has trouble remembering the codifications for the Neuro-Cortex and riding himself from his own repressed memories from the past, including issues with his own abusive father Torbert and bully jock Steve. Consequently, Octavius breaks out of his cell, reclaims his tentacle harness and rushes to retake the Neuro-Cortex from Max Modell, but will be facing more memories of his past failures when he comes across Carlie Cooper, who is enrolling at Horizon High as a new student.

16) “The Calm Before the Stormranger” (3)
As he moves on to his parents' second project, which involves his father's old A.I. assistant J.A.R.V.I.S. and a robot body hidden in the underground of Horizon High, Peter (as Spider-Man) battles a cabal of bounty hunters hired by Athena Gonzales of Athena Industries to destroy Stark Expo and the Central F.E.A.S.T. shelter as he gains a new ally with Stormranger, a mysterious armored female individual who has been protecting the F.E.A.S.T. shelters from any supervillain threat in the city. Coming close to learn of Gonzales' past grudges with his parents, Peter will soon learn that there are more amazing truths about Stormranger than he can believe. Meanwhile, Gwen and Anya play a helping hand about the robot body for Jarvis, and (through its special tracking monitors) they discover that there is one more living Parker in New York besides Peter himself and Aunt May, leading them to believe that Peter has a long lost sibling.
 * Outcomes: After analyzing Stormranger's biological DNA, Ace and Jarvis reveal to Peter that Stormranger shares his same biological DNA blood sample, making Peter realize that Stormranger is also his parents' daughter, and his long lost younger sister.

17) “Sons of Fathers” (4)
As his friends help him with his parents' third project, which involves a giant alien robot body (code-named "Arsenal") requiring a human consciousness to host, Peter works to reconnect with Stormranger (who was revealed by Ace and Jarvis to be none other than Richard and Mary Parker's second-born child and Peter's long lost younger sister), whereas Stormranger seeks to bring down a Oscorp facility controlled by Donald Menken, who seeks to sell Oscorp's technology for Hydra, and Ant-Man chases Yellowjacket, who seeks to take over Oscorp's technology for his own purposes. Harry Osborn (back to his mantle of Hobgoblin) and Venom (who is chasing a Symbiote spawn which possessed one of the Hydra agents) also join Peter in his fight, but Harry will be making heavy decisions after learning that his father Norman also played a shocking role in turning his best friend's parents over to the Red Skull.
 * Outcomes: Harry Osborn (disillusioned with his father's past actions and remorseful of the Parkers' tragedy) sacrifices himself to destroy the Oscorp facility as Menken (injected by Arsenal with a brain virus which forces him to permanently hallucinate himself in a dark world of Menken's worst nightmares) and Yellowjacket are arrested. After Harry's funeral, Stormranger (real name revealed as Teresa) still decides to part ways until the persecutors of hers and Peter's parents are dealt with, while Peter is encouraged by his friends to finish his parents' projects in theirs and Harry's memory.

18) “Seeds of Life” (5)
Determined to honor Harry's sacrifice by bringing Norman (who is revealed to have survived his apparent death and donned a new Green Goblin armor) to justice, Peter (followed by Gwen, Ace, Jarvis and Arsenal (now the host of the consciousness of Carlie's father Sergeant Chris Cooper)) travels to a HYDRA base where Viper is overseeing the creation of new human clones to be part of Red Skull's army. As he seeks to complete his parents' fourth and final project, which involves a emphatic insectoid alien (whom Gwen names "Mantis") which has a symbiotic link to him, Peter and Gwen run into Black Panther, who was pursuing the Shadow Council's last remaining member Madame Masque after she managed to break Otto Octavius out of prison so he would aid her in her goals with Arnim Zola's technology, and the Avengers, who are on a mission of their own against Hydra. While the three villains consequently clash against each other for control over the base, Peter seeks out a inactive clone body for Mantis to complete her transformation as Stormranger (real name revealed as Teresa Parker) returns seeking to settle her ordeals with Osborn once and for all.
 * Outcomes:
 * 1) Mantis earns a new humanoid form by merging with the strongest of the clone bodies created by Viper.
 * 2) Red Skull is hit by Green Goblin's out-of-control glider and dragged into Madame Masque's ship, which is obliterated by Arsenal along with Red Skull himself. The progress also results in Madame Masque's mask getting destroyed, rendering her powerless and freeing Octavius from her influence.
 * 3) Norman Osborn is defeated by Spider-Man, Stormranger and the rest of their friends and exposed to public eyes by Ace.
 * 4) Freed from Madame Masque's influence, Otto Octavius is taken to a mental hospital until he recovers.
 * 5) Teresa (pleased to know her parents' persecutors have been brought to justice) decides to live a new happy life with her brother Peter and Aunt May.

19) “Brand New Champions”
With his parents' projects finished and their persecutors facing justice for their crimes, Peter resumes his newly improved life as a Horizon High student and superhero while his sister Teresa (having decided to live with him and Aunt May) puts her new life on track as she enrolls at Midtown High School. The siblings and their friends (having formed the superhero group named the "Champions") soon find themselves against a new Sinister Six (consisting of Mister Negative, Silver Sable, Electro, Alistair Smythe / Spider-Slayer, Molten Man and Scorpion) organized by the Jackal, who is intending to fill the power void left after Norman Osborn's arrest and the fall of Oscorp, whereas Ronan the Accuser leads his spawns in the search for a weapon stolen from the Kree Empire for Oscorp.

20) “Real Wild Initiation”
While his friends work on their new headquarters (which takes place in his parents’ former research center, the Triskelion), Spider-Man is entrusted to look after and train Marcus Thompson’s younger brother Jack and Gwen's cousin Cassie Lang, who had just become Speed and Ant-Girl respectively thanks to Kree relics which granted them similar powers and resources of Quicksilver and Ant-Man respectively. Meanwhile, Carolyn Trainer (encouraged by the previous defeats of Otto Octavius and Norman Osborn’s downfall) once again dons the moniker of Lady Octopus in the purpose of redeeming herself from her previous actions in Octavius’ favors. Spider-Man will soon have to team up with Quicksilver, Ant-Girl and Lady Octopus when Madame Masque (now equipped with Octavius' tentacle harness and Osborn’s Green Goblin technology) resurfaces seeking the Neuro Cortex to rebuild her destroyed ship and retain her full power.

21) “Legendary Universes, Part 1: Message from the Unknown”
Wandering around the Champions’ new headquarters, Peter and Carlie come across a dimensional portal device which Peter’s parents used to collect the resources for their scientific projects, and decide to analyse it. During which, Spider-Man finds himself dealing with the ambitions of J. Jonah Jameson's son John, who had donned a power suit of Alchemax's technology to become the self-proclaimed superhero Captain Ultra with the goal of clearing his father's name out of his role in the Parkers' tragedy (but also to make money with his popularity as Spider-Man acknowledges). Things get no better when Yuri Watanabe's former mentor August Roman (also known as the Regent) emerges with a power-replicating suit of Alchemax tech and seeks to bring New York to his knees. Spider-Man begrudgingly teams up with Captain Ultra to take down Regent and stop him from reaching the portal device, which the Regent plans to use to collect the discarded Oscorp protocols which have gone missing in the dimensions Peter's parents explored.

22) “Legendary Universes, Part 2: Webs of the Force”
Certain that the Regent will come back from the Negative Zone (where Captain Ultra imprisoned him before Spider-Man could strip Regent off his suit's Power-absorbing functions), Spider-Man decides that he must travel into the dimensions his parents explored to seek and destroy the discarded Oscorp protocols before Regent can return to retrieve them. Followed by Stormranger, Firestar, Lin Lie, Nova and Ace, Spider-Man's first journey takes place in AC-5's home dimension: the universe of the Jedi Alliance. There, they team up with Rey Skywalker and her allies from the New Jedi Order and the Resistance to take down the Dark Nation, a cult-like organization composed of former members and loyalists of the First Order and led by Captain Phasma with Oscorp's Green Goblin technology, and save the Galaxy once more.

23) “Legendary Universes, Part 3: Unlimited Speed”
Resuming his journey across dimensions to destroy the Oscorp resources to prevent Regent's rise to power, Spider-Man now travels alongside Tigra, American Knight, the Lion King, Wave and Jarvis into Jarvis's home dimension: the universe of Sonic the Hedgehog and the Freedom Fighters (consisting of Sonic and his friends Sally Acorn, Miles "Tails" Prower, Sticks the Badger and Knuckles the Echidna). There, the Champions and Freedom Fighters work together to destroy prototypes of Otto Octavius' tentacle harness which fell in possession of EggRobo, who seeks to take over Earth's Technology Center to roboticize humans and other organic life forms. The heroes must also contend with Dr. Robotnik, who seeks to regain control over EggRobo and retrieve Jarvis' robotic body by any means necessary.

24) “Legendary Universes, Part 4: Heroes in Disguise”
Having reached halfway of his objective, Spider-Man now travels alongside Ms. Marvel, Ant-Girl, Speed, Inferno, Brawn and Arsenal into the home dimension of Arsenal's robot body: the universe of the Transformers. There, they team up with Optimus Prime and the Autobots to defeat the Predaking, who was resurrected by Kree technology which was salvaged and discarded by Oscorp's engineers weeks ago and now seeks to convert human technology to his own liking and take revenge on the Decepticons for attempting to enslave him. The heroes also have to contend with Megatron and his Deception followers, who wrongly accuse the humans for unleashing Predaking to the world and Cybertron.
 * Crossover with the Transformers franchise

25) “Legendary Universes, Part 5: Of Spiders and Turtles”
With only one step of his objective remaining, Spider-Man now travels alongside Ghost-Spider, Kid Arachnid, Spider-Girl and Mantis into the fourth and last dimension his parents explored: the universe of the Teenage Mutant Ninja Turtles. There, the Spider-Team and the Turtles team up to take down a clan of ninjas who were physically mutated by samples of the Jackal's animal formulas and are on a rampage across New York. Things may get more serious when the Shredder seeks to tame the mutated ninjas and convert as hounds of the Foot Clan to bring New York to its knees.

26) “Legendary Universes, Part 6: Ultimate Alliance”
With the Oscorp resources destroyed, Spider-Man and the team find themselves ready to take down Regent, who returns from his imprisonment more powerful than he was before after his power suit absorbed Antimatter from the Negative Zone. Even though Regent manages to subdue and drain Captain Ultra, replicate Doctor Octopus' technology and bring a new army of his own from the Negative Zone to Earth, Spider-Man and the team are still not alone, as they are joined in the battle by the Avengers and the heroes from the parallel dimensions (the Jedi Masters, the Freedom Fighters, the Autobots, the Teenage Mutant Ninja Turtles and their allies) to defeat the Regent's army and save the world.

Differences Between the Original Season 2 and the Original
Although the first five episodes of Season 2 remain the same, the shows follows a different storyline, with different outcomes.
 * Despite still becoming Ghost-Spider and Spider-Girl respectively, Gwen Stacy and Anya Corazon remained unaware of Spider-Man's identity of Peter Parker. In Webbed Champion, they are eventually revealed to have learned during Spider-Man's battle with Venom and Scorpion.
 * Additionally, Peter was unaware that Anya was operating as Spider-Girl in the original show, but was aware of this fact in Webbed Champion.
 * New characters appear in the show, such as Black Panther, Teresa Parker, Inferno, and more.
 * Mary Jane Watson, who had a minor cameo in the original show, now has a central role in the Season, appearing as the show's version of Tigra.
 * Liz Allan also has a expended role, on which she becomes a new version of Firestar.
 * Along with expanded/speaking roles in the show, Captain America and Captain Marvel's designs are altered; Captain America now uses his design from Avengers: Black Panther's Quest, while Captain Marvel now resembles her counterpart from Marvel Rising and sports the costume worn by Brie Larson's character in the MCU.
 * Spider-Man's battle with Eddie Brock / Venom is altered; in the original show, Venom managed to kidnap the key figures of Peter's life (Gwen, Anya, Aunt May and Max Modell) and hold them hostage in Horizon High to draw Spider-Man out. In Webbed Champion, the battle is now consisting of Scorpion against both opponents, and including Tigra on Spider-Man's side.
 * Compared to the original story, J. Jonah Jameson is less sympathetic and has a more antagonistic role in Webbed Champion, on which he hires Scorpion to intercept Peter for pictures of Spider-Man, and is revealed to have had a role in Richard and Mary Parker's death by covering their deaths at Red Skull's hands as a "tragic, inevitable accident" for protection money.
 * The "Bring on the Bad Guys" arc, where Otto Octavius (through the Living Brain) places a bounty on Spider-Man's head and sends numerous super-villains after him, is replaced for the "City of Heroes" arc, on which Peter's friends slowly become new superheroes and join his battles against crime, although Otto Octavius being on the Living Brain is still intact.
 * The original Season had the "Superior Spider-Man" arc (from "Living Brain" to "Superior"), where Doctor Octopus swapped bodies with Spider-Man to try to become better than him. In Webbed Champion, however, the arc is replaced for "Family Business" arc ("Brainstorm" - "Seeds of Life"), where Peter works to solve secrets about his family's past.
 * Therefore, Doctor Octopus' plan (which succeeded in the original show) fails in Webbed Champion.
 * Plus, Peter's relationship with friends is not damaged by Octavius like it was in the original story, nor does he leave Horizon High to re-enroll at Midtown High.
 * Despite their details and traits from the original show remaining the same, Cloak and Dagger's origins are altered. In the original show, they were subjects of Tiberius Stone's experiments in Alchemax. In Webbed Champion, they are depicted as a couple of Inhumans who currently reside in Attilan, and work closely for King Black Bolt and Queen Medusa.
 * The season's final arc consists of a crossover with the fictional franchises of Lucasfilm's Star Wars, Sega's Sonic the Hedgehog, Hasbro's Transformers and Mirage Comics' Teenage Mutant Ninja Turtles.
 * In the original show, Adrian Toomes / Vulture was the main antagonist in the final arc "Goblin War", on which he led the Goblin Nation (as the Goblin King) to attempt to destroy New York. In Webbed Champion, the final arc's main antagonist is August Roman the Regent, who takes control of Jackal's new Sinister Six and seeks to establish a new order in New York City through iron fist.
 * While still a minor antagonist in the final arc, Alistair Smythe never enrolls at Horizon High in Peter's place.
