“Ultimate Spider-Man”
"Alright, everybody. Let's do this again one last time. My name is Peter Parker. I was bitten by a radioactive spider... and for this last one year, I've been the one and only Spider-Man. I’m pretty sure you know the rest. I couldn't save my Uncle Ben, who died right after I was bitten by a spider, but I did carry on the one lesson he taught me: that Great Power will always come with Great Responsibility. Since then, I've been fighting criminals and saving the citizens whenever and wherever I'm needed. So far, no one else knows my secrets except the people I love and trust the most. Those including my aunt May, my cousin Felicia, who's been fighting crime as Black Cat, and my beautiful girlfriend Mary Jane Watson. And so on, whether I'm wanted or not by citizens... even this loudmouth from D.B. J. Jonah Jameson... I will fight for what's right. And let nothing and no one stop me."

"Very well, troopers... let's do this again just one last time. My name is Steve Rogers. I was subjected to a Super Soldier formula for the U.S. Army... and for a lifetime ago, I've been the one and only Captain America. I’m pretty sure you know the rest. I led an army against Hydra in World War II... until that fateful day when I was frozen in the Arctic ocean for decades... and reported killed in action. Then, I woke up in the modern world. Found still alive by the world's new military unit called S.H.I.E.L.D.. Despite how shocked I was with how drastically the world changed while I was sleep, I continued doing what I do. Serving my country, fighting new threats... and also old threats like Hydra. Also, I may not have my old war colleagues, but I have new ones to lead for the greater good of this world. Because that's what heroes do. And together, we'll do everything it takes to keep the innocents safe."

“Ultimate Tigra”
"Some would call this a horror tale. Because it involves a girl who carries a terrifying secret... involving a ferocious, unstoppable cat creature that strikes fear in the criminals' hearts. But still aspires to do what heroes do. For me, this isn't a horror tale. It's a family history. My name's Mary Jane Watson. For a long time, I've been searching answers about my past. To know who my father is. For a while, I thought it would be just a regular, but beautiful family reunion. But then, it turned out to be something more. Something beyond my most childish imaginations. Still, whatever that is, it turned out to be a revelation of what I really am. And now, I have the means to do what must be done... and what the man I love the most does."

"Alright, let's do this again just one last time, shall we? My name is Carol Danvers. I've been hit by the explosion of a Kree ship engine and absorbed its energy... and for the last twenty years, I've been the one and only Captain Marvel. I'm pretty sure you know the rest. In the first five years of my new career, I traveled around the galaxy, I stopped the Kree from decimating other alien worlds living in the galaxy, worlds including the Skrulls, Shi'ar and more... I made some interesting friends... and (chuckles) I also adopted this alien kitty cat... and resumed what was left of my old life on Earth. Which started by forming this close... I mean really, really close relationship with Earth's first Avenger himself. We got married... and we had a little girl, who grew to be just like us. I know. It's an unbelievable strange thing to happen. But, what can I say? It's another strange thing that does happen. But, still part of what I am now. And will be for now on."

“Ultimate Hulk”
"Hi, Betty. I know it's going to be hard for me to explain... but I know you're gonna believe me. So when that gamma experiment went wrong, I was thought to be dead for three years, but I was infected by it. Now every time I get angry or nervous, I turn into this... a rampaging monster that destroys everything he hates. This monster they call "the Hulk". Ever since then, I've been on the run from the government and the army. Because of some faces who don't want to cure me. Only make a weapon out of me. Worse, even more of me. I'm trying to fix it, I really am. But I need your help. Please. You're the only one I can trust, Betty...."

I got a prototype of the Pym Particle suit as a birthday gift from my dad, and on my first lucky try, I've proven myself as fit as he was of becoming a superheroine like he is. Not bad for a 10-year-old, huh? It's pretty fun, although I do need to carry on the important lessons that my dad and other superheroes learned. Including Spider-Man's lessons about power and responsibility. It's gonna hard, but it's still gonna be fun all the same! Because, like daddy said, this is what heroes do."

“Ultimate Black Panther”
"For many years, our family has worshiped the panther goddess Bast. As the story goes on, close to a million years in the past, the man who would be known as the first Black Panther met her and was granted his own kingdom which was filled with a metal known as Vibranium, which could not be found anywhere else on the planet. "You have found me", she said, "and as a reward, I shall grant you your own land, as well as mystical powers beyond your wildest dreams." She allowed the man to consume her Heart-shaped Herb, breaking all of the man's limits and turning him into the first Black Panther and the first ruler of the kingdom that would one day be known as Wakanda. His son took over when he died. Their son took over when they died, and so on. The Cycle... the Royal Cycle was born. And one day... your time will come when mine ends, T'Challa. Your time to become the king and protector of Wakanda... the Black Panther."

Main

 * Spider-Man / Peter Parker - A 17-year-old teenager who was bitten by a genetically-modified spider during a field trip to Oscorp. While he focuses on both his career as Spider-Man and his normal life as a high-school student, Peter also aspires to be a social support counselor, as he spends his time interviewing and granting support advice for the shy and insecure as well as LGBT people.
 * Appearance: The same as in the original comics. His first Spider-Man suit resembles the one worn by Tom Holland’s character in the Marvel Cinematic Universe. The second one resembles the one worn in the 2018 video game.
 * Tigra / Mary Jane Watson - Peter’s 16-year-old girlfriend and classmate. She is an half-human, half Titanian Tiger hybrid (daughter of F.E.A.S.T. nurse Mary Watson and Titanian Tiger Soto) with the ability to shape-shift into a humanoid tigress with the abilities of Fire and Ice Breath, Hypnosis and the “strength of ten tigers combined” (provided with Superhuman Strength, wall climbing, Superhuman leaping, and able to run and swim in incredible speeds). She can also use a technique called the "Maharaja's Roar", on which she lets out a powerful roar which can conjure wind and fire and summon the astral projection of a tiger head (presumably that of its namesake tiger god). This power can be used in both human and Titanian Tiger form. She initially wore no clothes in her Titanian Tiger form until she was given a new two-piece leotard suit which adapts to her powers after earning membership of the Avengers.
 * Appearance: The same as in the original comics. Her Tigra persona is based on Greer Grant’s variant in the comics, but with the costume colored on blue and added with two golden bracelets.
 * Captain America / Steve Rogers - The leader of the Avengers and a World War II veteran, who was enhanced to the peak of human physicality by an experimental serum and frozen in suspended animation before waking up in the modern world. Along with his iconic Vibranium Shield (which has been his main weapon since World War II), Rogers also wields a pair of special Wakandan gauntlets provided for him by the Wakandan Design Group in memory of king Azzuri. He is a mentor to Spider-Man and his friends, and is married to Carol Danvers, with whom he has a teenage daughter named Liz.
 * Appearance: Based on Chris Evans’ character in the Marvel Cinematic Universe.

Once she died, the bomb detonated and caused a building with innocent people to collapse (though every citizen was saved in time by the Avengers while only William Stryker's henchmen, who were closer to the bomb, were killed). Kasady was later killed by a vengeful Hyperion, though he was successful in damaging some bit of Jameson's reputation.

He is a student in Midtown High and one of the attendants to Peter Parker's support council, on which Harry sought for Peter's advice while confessing he was gay, something of which Norman (who wanted his son to be a superior man) never knew and would have been disgusted to hear but to which only his mother Emily expressed support for. Once he learned of this, however, Norman killed Harry along with Emily.
 * Appearance: Based on Dane DeHaan's character in The Amazing Spider-Man 2.
 * Joana Madison / J. Jonah Jameson Jr. - Jameson's daughter (originally son) and one of the attendants to Peter Parker's support council, on which she confessed to be a trans woman as she claims to have "thought of herself as a man until she begun seeing herself as a woman".

Her death soon led her grief-stricken mother to create the Metagirls, committing suicide in progress.
 * Appearance: A younger version of Jared Leto's interpretation of Rayon in .
 * Captain Ultra / Rowley Jameson - J. Jonah Jameson's dedicated, but rather immature older son, who operates in a Alchemax nano-tech suit provided by his mother which grants him super powers (flight, increased strength and energy blasts). Despite his dedication, he lacks the willpower to face more experienced foes and villains such as Whirlwind (much to Marla's disapproval despite Jameson's blind confidence on his fame) and is always facing embarrassment of "losing" to other superheroes, even to Ant-Girl (who even criticizes that he "wears a big blue diaper over his pants") in her first day of crime-fighting. Later, during Ultron's attempts on Jameson's life, Captain Ultra fought Ultron, but only to be easily defeated by him and killed by Green Goblin, who proceeded to violently beat him to near death, and Carnage, who begun devouring him while Goblin forced him Jameson to watch in horror and mocked: "You'll be hearing this in your nightmares forever.

Marla is also a high-tech scientist and head of Alchemax and showed respect for Peter Parker's work as a support councilor, which helped her daughter Joana overcome her inner doubts. Following Joana's unjust murder, Marla was reported to have been mourning for one month straight and seemly spoke to no one else except her lab assistant Anne Weying. It was revealed, however, that Marla had been collecting blood-samples of other women (Weying, Betty Brant, Rio Morales, Natasha Romanoff, Yuri Watanabe and Ice Elf Elphane) and herself along with six elemental alien gems to complete the creation of her "new children", the Metagirls. Marla eventually did so by locking herself in a small lab and, after broadcasting a farewell message to New York, used high-tech machines to drain her own life force and transfer them to the Metagirls, who soon awakened and adapted to Marla's young mind, intelligence and personality. Once the process was complete, Marla was soon found by Weying and Watanabe having aged rapidly from the strain and died at an artificially advanced age. Shortly after Jameson was arrested, it was later revealed she knew her husband killed Joana out of his hatred for LGBTs and has "chosen to die so that she wouldn't leave to be married with a murderer", a public statement which would soon haunt the incarcerated Jameson forever.
 * Appearance: A younger variant of Rosemary Harris' interpretation of Aunt May in Sam Raimi's Spider-Man trilogy.
 * Anne Weying - Brock's fiancee and a Alchemax scientist who is Marla's lab assistant. She is shown to be greatly loyal to her employer and strongly supports her secret Metagirl Project, as she felt sorry for Marla's loss of her daughter Joana and "couldn't refuse a grieving mother". Weying also seemed to view Marla as a mother figure for herself, as she was shown tearfully mourning her after she sacrificed herself to fully bring the Metagirls to life. Later, during a date with Brock, Weying was confronted by J. Jonah Jameson, who wrongly blamed her and her fellow Alchemax scientists for Marla's death and shoot her dead in front of Brock. Her death was nearly avenged when Brock (as Carnage) cooperated with Ultron and Green Goblin in incriminating and exposing Jameson, despite failing to kill him.

She attempted to stop the vessel by smashing the Stone's container, partially disabling the vessel's engines. Once she physically handled the stone, it opened a wormhole into space, sucking Wanda into it and causing a shock wave which completely obliterated the vessel and knocked Rogers and Red Skull into the frozen sea. Unknown to Rogers and Skull, in Captain America's second arc, it is revealed that the stone teleported Wanda into other limits of space, where Wanda was slowly transformed into a cosmological entity with infinite knowledge.

In the Earth-2 version, Liz is given with the surname Danvers-Rogers, and was re-imagined as the daughter of Steve Rogers / Captain America and Carol Danvers / Captain Marvel.
 * Also, Firestar (who is Angelica Jones like her main counterpart) is re-imagined as a Inhuman, Jessica Jones' twin sister and one of the two halves of the Phoenix.
 * In the original story, Janet Van Dyne was a Mutant of Asian descend who frequently suffered from physical and verbal abuse by Hank Pym, with whom she had a rather complicated relationship. In the Earth-2 version, her looks and origins are far more loyal to her appearance in The Avengers: Earth's Mightiest Heroes!, although her costume still has details from the first suit worn in The Ultimates.
 * In the original story, Black Cat was a lawless vigilante who at one point expressed romantic interest on Spider-Man until she learned of how young he was. In the reboot, Black Cat is re-imagined as a more moralized superheroine while she as Felicia is also re-imagined as Peter's cousin, daughter of his Aunt May, and a young Lesbian girl.
 * In the original story, Natasha Romanoff was the assassin and spy code-named Black Widow who was sent to infiltrate S.H.I.E.L.D. and the Ultimates to tear them apart and played a part in killing Hawkeye's family. In the reboot, Natasha is re-imagined as a normal, yet sympathetic citizen and Russian immigrant to the U.S.A. who happens to be a ballet instructor and one of Mary Jane's teachers.
 * The Black Widow in this reality is Yelena Belova, who is a major antagonist to the Avengers.
 * In the original comics, Hulk had a more antagonistic role, depicted as not only being incredibly destructive and violent but also downright sadistic (as Hulk even displayed cannibalistic traits), and rarely acted in a heroic manner like when he fought alongside the Avengers. In the reboot, Hulk / Bruce Banner is more similar to Mark Ruffalo's character in the Marvel Cinematic Universe, with his present day form displaying the same looks and behavior as in Avengers: Endgame.
 * In the original comics, Carol Danvers was a non-powered soldier and S.H.I.E.L.D. Captain who at one point took the role of director until Gregory Stark's death. In the reboot, Danvers is still Captain Marvel as in the ongoing comics and in other media including the same name MCU film and Avengers: Endgame, and she is Steve Rogers' wife, Liz's mother and a founding member of the Avengers, replacing the Black Widow in the comics.
 * As in Avengers Unleashed, Bruce Banner's lover Betty is re-imagined as General Ross' adopted daughter instead of biological.
 * In the original Ultimate series, Kitty Pryde was one of the love interests of Spider-Man, and her relationship with him brought some conflict with Mary Jane Watson. In the Earth-2 version, however, she remains just friends with him and is re-imagined as Mary Jane's younger cousin, and a growing Lesbian girl.
 * In the original Ultimate comics, Venom was the second stage of a genetically created "suit" designed by Richard Parker (Peter's father) and Eddie Brock Sr. (Eddie's father) as a cure for cancer meant to bond to the user and protect them from internal and external harm. In the reboot, Venom is still an alien organism as its Earth-616 counterpart, although this version found a suitable host on Jack Thompson (Flash Thompson's uncle) and never bonded with either Peter Parker or Eddie Brock, although the Symbiote did duplicate Spider-Man's powers by devouring the lab spiders of Oscorp.
 * In the original Ultimate comics, Carnage was a self-regenerating vampiric organism created from DNA samples of both Spider-Man (Peter Parker) and the Lizard, and combined with samples from Richard Parker's symbiotic suit research. In the reboot, Carnage is re-imagined as an alien spawn of the Symbiote invasion force led by Riot. Also, unlike other incarnations where Carnage's host was Cletus Kasady, this version of Carnage is bonded to Eddie Brock.
 * In the original story, Norman Osborn / Green Goblin knew Spider-Man's identity since he saw him being bitten by a radioactive spider. In the reboot, however, Osborn was distracted witnessing the crossfire between Crossbones' and Punisher's gangs, and did not notice Peter getting bitten by the spider. So, Osborn never got to know Peter's connection to Spider-Man.

Adaptations

 * Mary Jane Watson as Tigra and Cassie Lang as Ant-Girl appear in Iago PUC's version of Marvel's Spider-Man and Marvel's Spider-Man: Webbed Champion as main characters.
 * Marvel: All New, All Different Chronicles incorporates several versions of the characters in Ultimate Marvel: Earth-2, such as Starforce and the Guardians of the Galaxy. Events from the comic book series (such as Spider-Man's origins, the foundation of the Avengers and Captain America and Captain Marvel's marriage) are also adapted.
