“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."

- Spider-Man introducing himself to the readers Spider-Man's arc is set in the series' present day period, on which Peter Parker has been Spider-Man for one year since he received his powers from a radioactive spider bite and witnessed his uncle Ben getting killed during a crossfire between Frank Castle's mercenaries and Brock Rumlow's Hydra Ops. The arc focuses on Peter's duties and responsibilities as a normal citizen and as Spider-Man, including his search for answers about his family's past and his battles against several super villains including Green Goblin and Doctor Octopus as well as against criminal and violent activities, such as Homophobia and Genocide of non human beings (including Mutants and Inhumans).

“Ultimate Captain America”
"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."

- Captain America introducing himself to the readers The first arc of Captain America's story happens in the period of World War II until the moment he was frozen in the Arctic sea. The second arc, which happens sixteen years before the events of Spider-Man's story, happens one week after waking up at the modern world until he meets and marries Carol Danvers / Captain Marvel.

“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 crimminals' 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."

- Mary Jane Watson narrating in the introduction Tigra's arc happens one year before Spider-Man's arc does, and focuses on Mary Jane Watson's search for answers about her origins and her father's true identity, which leads up to her encounter with her older half-sister Ava Khan and her transformation into Tigra.

“Ultimate Captain Marvel”
"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 travelled 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 five years, but I was infected by it. Now everytime 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! Becuase, like daddy said, this is what heroes do."

 * Stan - A Comic Book shop owner and friend of New York's superheroes (most closely Spider-Man, Captain America and Iron Man).
 * Appearance: Based on Stan Lee.
 * Harry Osborn - Osborn's son. 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 advices 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 Jameson / 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". Though she also had major support from her mother Marla, Joana was neither less killed by her own father, who had a disgust and genocidal hatred for LGBT people. 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 .
 * Marla Madison - Jameson's ex-wife who, unlike her ex-husband, views Spider-Man as a hero and does not treat him like a menace. 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 hightech 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 Venom X) cooperated with Ultron and Green Goblin in incriminating and exposing Jameson, despite failing to kill him.
 * Appearance: Based on Bryce Dallas Howard's interpretation of Gwen Stacy in Sam Raimi's Spider-Man trilogy.
 * Eugene "Flash" Thompson - Peter's rival and classmate and a ambitious, self-centered jock in Midtown High. While he is considered popular to other students, he also heavily dislikes being called by his true name Eugene (which he feels embarrassment of) instead of his nickname Flash. While he also lives in his deceased parents' mansion, he also happens to be a rather rebellious, spoiled delinquent who takes little responsibility of his actions and always puts his life at risk because of the mass of fortune he interited from his father, as he usually rides at night with his Mazda RX-7 secretly participating in illegal against dangerous thugs. He is indirectly responsible for Scorpion's transformation into a scorpion monster.
 * Appearance: Based on Tony Revolori's character in the Marvel Cinematic Universe.

Differences Between the Reboot and the Original Franchise
Since this new series is a reboot to the original Ultimate Marvel storylines, there are a series of changes and differences done in the story.
 * Gwen Stacy (who was a rebellious teenager close to Peter's age before her death by the hands of the Carnage symbiote in the original franchise) is reimagined in the reboot as an twelve-year-old pre-teenager and more loving girl who is soon bitten by a new Super Soldier spider which leads to her transformation into Ghost Spider.
 * While she is still Mary Jane's best friend, Liz was surnamed Allan, she was the daughter of the mutant cannibal Blob and a mutant under the codename Firestar. In the Earth-2 version, Liz is given with the surname Danvers-Rogers, and was reimagined as the daughter of Steve Rogers / Captain America and Carol Danvers / Captain Marvel.
 * 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 reimagined as a more moralized superheroine while she as Felicia is also reimagined as Peter's cousin, daughter of his Aunt May.
 * In the original story, Natasha Romanoff was the assassin and spy codenamed 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 reimagined 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.
 * As in Avengers Unleashed, Bruce Banner's lover Betty is reimagined 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 reimagined as Mary Jane's younger cousin.
