The director of S.H.I.E.L.D. Tasked with forming the super soldier organization called the Ultimates. Tends to be paranoid and has lots of secrets. Notably, Bryan Hitch and Mark Millar asked Samuel Jackson for permission to use his likeness for this version of the character which has led to Jackson playing Fury in multiple recent Marvel movies (with more to come.)
Subverted when dealing with Miles Morales. First meeting him, he talks to the boy. When in danger, he escorts him by hand to what he thought to be safety. After Miles proves himself, he gives him a new costume (oddly the one Miles was hoping to design himself) and and allows him to be Spider-Man.
Everything that has happened in Ultimate Spider-man is partly his fault. After Bruce Banner failed to recreate the super-soldier serum, Fury offers defense contracts to anyone who can create it which led to Osborn becoming obsessed with Oz which in turn created Spider-man. Not to mention a fair amount of super villains that both Spider-Men had to deal with were in someway connected to Fury.
Daughter of General Ross and the on again off again love interest of Bruce Banner. Betty faces the grueling task of marketing the supersoldier project as a superhero team and it only gets harder when the threats they were formed to address fail to emerge right away. Seemingly cold and manipulative, which is not a good match for Bruce. In Ultimate Wolverine vs Hulk, she becomes the Ultimate Marvel version of She-Hulk.
Issue one of volume one opens with Steve Roger's final World War two mission. He is discovered in a glacier just in time to make him a part of the premier line up. Augmented by a unique supersoldier formula that has so far only worked on him, Captain America has peak human physical abilities and fighting skill. Being wrapped in the flag makes him a natural choice for leading the team even if he's 60 years behind the times. A lot of his personal arc in the first two volumes has to do with him adjusting to the realities of 60 years suddenly passing, from culture shock to finding his friends old or dead.
He deliberately tracked Miles Morales down just to tell him that he could no longer be Spider-man in spite of Miles having approval of Nick Fury, Aunt May, Gwen Stacey, and Mary Jane. It took Miles stopping the Rhino and fending off a HYDRA attack for Cap to approve of him.
Took a Level in Kindness: Sort of. Ever since Peter's death, his old-fashioned approach started to whither away. When he eventually came back and met Miles Morales, he started to be more accepting of the kid and eventually became his greatest supporter(he even had Miles fight along side the Ultimates which is something he deliberately banned Peter from doing). He reserves his initial gruff persona for those who wastes his time(the representative of the then defected California) or people who he knows can do better(the Lawyers arguing for and against the incarceration of Bruce Banner). By the end of the Ultimate Comics run, Captain America is just a less tolerant but still heroic version of his 616 counterpart instead of a straight up hero.
Bruce's life's work has been trying to replicate the success of Captain America, the first botched result of which, led to his transformation into the Hulk. In this universe, the Hulk is more of an unleashed id than the angry child of his classic counterpart, using his tremendous physical strength to address all of Banner's insecurities in the most direct ways possible. Having stabilized himself, he chooses to Hulk out in the first half of volume one giving the team something to fight. They choose to cover up the connection between Banner and the Hulk turning their biggest mistake into their biggest media success.
Adaptive Ability: Part of this Hulk's unique power set is the ability to mutate to better survive, no matter the conditions. For example, in about 7 seconds, he changes to be able to survive on the surface ofVenus.
Gone Horribly Right/Gone Horribly Wrong: The Hulk's physical abilities are all what Banner designed them to be, but something went wrong, causing the Hulk to be the bestial Id-driven monstrosity it is; Banner designed the Hulk to be as smart as it is strong.
I'm a Humanitarian: The Hulk persona is quite notoriously a cannibal, which has been explained as it being the ultimate expression of how the Hulk is Banner's darkest emotions and traits made manifest, a living rebellion against all the restraints Banner places on himself.
Super Strength: Officially the strongest thing in his universe, or near enough to it.
The Unfettered: Whereas his mainstream counterpart is ultimately moderated by Banner's desires, the Ultimate Hulk is a living expression of Banner's unrestrained id, meaning he has no moderations at all.
Villain Protagonist: A Psychopathic Man Child with cannibalistic tendencies whose brain basically revolves around his desires for killing, eating and having sex with whatever he chooses, without any form of moral or mental restraints.
A biologist and one of her husband's first successes in engineering superheroes. Or so it seems. In truth, this universe's Wasp actually gets her powers from being a mutant. Her husband Hank is able to reverse engineer what she does to create his own powers. The Wasp is able to self miniaturize, fly with gossamer wings, and fire bioelectric bolts from her hands. While not much of a heavy hitter, her stealth and precision allowed her to take down the Hulk (by flying in his ear and zapping his brain.)
An extraordinary Jerk Ass and the head of R&D for supersoldier research, replacing the unstable Banner. Pym is able to reverse engineer his wife's shrinking powers to allow him to grow to nearly 60 feet tall. His Giant Man formula ends up being the most successfully replicated aspect of the project giving the Ultimates an entire platoon of Giant Men (and his ex wife in volume two). Too bad he can't control his temper leading him to abuse Janet and embarrass the team publicly before getting kicked out.
Not actually an official part of the team. Thor came to Earth in the modern era to warn the world about the conspiracies of the military industrial complex. That said, he is not so distrustful of the military that he would miss the noble qualities some of the Ultimates possess so he works with them when needed. One of the questions of the first two volumes is whether Thor is the actual Norse God of Thunder or a delusional super soldier. This gets resolved in the second volume.
Real After All: During the alien invasion, there was a bomb set to literally destroy the world. Janet and Natasha called for Tony Stark to deactivate it and when he came, they thought he was going to carry the bomb with him to space and pull a Heroic Sacrifice. Not quite. Tony got the bright idea to have Thor teleport the bomb to a separate dimension because he is a god. Hearing of Tony's plan, both Natasha and Janet were delirious about how nuts Tony was to believe a man who was sent to an insane asylum calling himself the God of Thunder. Of course, they stopped doubting it when it worked.
Worf Effect: Originally promoted as one of if not the most powerful beings in the Ultimate Universe only to get his butt kicked or shown up in some way with his only victories against beings far weaker than him.
Tony Stark is a brilliant and enormously wealthy weapons manufacturer who gets brain cancer and decides to spend whatever time he has left saving the world. He's known for being eccentric, a playboy and almost perpetually drunk. Like Giant Man, his "powers" are replicated eventually giving the team multiple armored soldiers.
The Alcoholic: He drinks to numb the pain caused by his brain tumor.
Brain Uploading: He was able to upload his consciousness in his Iron Man suit due to his brain having prolonged exposure to the Infinity Gem in it. So the Infinity Gem gave him mental powers so he can upload his brain into anything with a CPU.
Deadpan Snarker: The resident smart ass on the Ultimates and Future Foundation.
Healing Factor: Because of having undifferentiated neural tissue throughout his body, Tony can heal from injuries and regrow organs and limbs. It's not effective enough to cure his tumor, however.
Ill Guy: He has an inoperable brain tumor, and his messed up neural network leaves him in eternal pain. But he doesn't let it get him down, too much.
It Was with You All Along: It turns out that brain tumor that's caused Tony so much pain was in reality an Infinity Gem that somehow got trapped inside his head. Sadly it leads to him getting killed off shortly afterwards.
Not Quite Dead: After Reed Richards performs brain surgery on Tony to get the Infinity Gem inside his head, he cuts off all medical support thats keeping Tony alive throughout the process. His body is gone, but he survived by Brain Uploading to his suit.
Natasha Romanoff is a former KGB spy/supersoldier turned US Black Ops. Along with Hawkeye, she is brought onto the public team with a fake background. Eventually becomes engaged to Tony Stark. Eventually revealed to be a traitor in Volume 2 using Stark and her Ultimates membership to undermine the team and steal Tony's fortune, though this doesn't work.
Badass Abnormal: Has cybernectic implants that increase her speed and strength
Black Ops soldier turned superhero. Deadly accurate with any ranged projectile. In Volumes One and Two, he mostly uses his bow and thrown weapons. In Volume Three after losing his family he switches to guns.
Badass Normal: Until Jeph Loeb's run, Hawkeye was a normal human who'd reached his ridiculous level of skill and accuracy through training, this is even lampshaded by Hawkeye himself in his first appearance in which he chastises Black Widow for chatting to him during combat because he doesn't have her cybernetic enhancements and so can't do both at once.
Fingore: His infamous escape scene in the Grand Theft America arc, which involved ripping his fingernails out.
Improbable Aiming Skills: To the point where he may as well just be called Bullseye, since he's at least as accurate as the 616 version.
Jerk Ass: As Millar described him "He's a Neo Con", and also a bloodthirsty mass-murderer who self-admittedly used to be much like The Punisher until he was recruited by black ops to kill for the government instead. However, he was also a devoted family man on the side, so there are different sides to him.
There Are No Therapists: It's very clear he's suffering from Post-Traumatic Stress Disorder after his family's murder, and yet nothing's being done about it.
Following the events in Ultimate X-Men, Pietro and Wanda Maximoff, the children of prominent mutant terrorist Magneto, agree to join the Ultimates acting as team members and informants. They tend to be aloof with marked aristocratic and European sensibilities. They also spent enough time together that it was obvious what was going on between them before it was stated explicitly in Volume Three.
De-power: In his first appearance Loki is a reality warper whose powers mysteriously fade during the last battle. Later appeaerences portray him more as a traditional sorcerer instead of a reality warper with no reason given for the loss of power.
The Liberators (Colonel Abdul al-Rahman, The Abomination, the Crimson Dynamo, Perun, Hurricane, Swarm & the Schizoid Man)
A super soldier team put together by nations worried about the escalation of the American super-soldier initiative. They invade the United States in volume 2. The team is run by Loki.
Anti-Villain: Most of them are utter bastards, but the Colonel, at least, seems to be a genuinely good guy who just happens to be fighting for the wrong side. Indeed, his death scene is probably the most respectful send-off anyone's ever gotten in the entire series.
Always Someone Better: Played with. They were certainly trying for this. The Abomination was the Hulk with brains. Swarm summons armies of wasps. Crimson Dynamo has a bigger suit no doubt intended to be higher powered. etc. But the Ultimates counter by revealing upgrades or levels taken in badass. And in the case of the Abomination, being an intellectual isn't very useful when your best assets are your rage and your fists.
Butt Monkey: The majority of them. Perun gets a special mention since he not only was never seen in combat, but was the only Liberator to have willingly surrendered.
Heel-Face Turn: Saw the error of his ways after Cataclysm after witnessing the alternate life he would have had if he stayed with Sue and remained a good person.
It Is All About Me: He views himself as the sole savior of the universe and feels everyone who is against him is wrong.
Knight Templar: He wishes to solve all the problems of the Earth, no matter the cost.
Reed Richards Is Useless: A dark take of the trope. After getting stopped and stalled from every scientific discovery that he ever made, Reed Richards just loses it and starts taking out every scientific hero or foundation who could possibly stop him.
Turned Against Their Masters: Eventually, the computer of the City comes to the conclusion, that Richards' megalomanic and warmonger attitude is obsolete, and only hinders the further development of the City.
