Characters not belonging to any specific titles:
Pluskommander Geneheris HalaSon Marh-VehlAn alien of the Kree Empire, Voidnaught Marh-Vehl was assigned to undercover work on Earth, pretending to be Dr. Phillip Lawson, a slightly ditzy NASA scientist. During his time on Earth, Marh became attached to humans, and decided they were worth protecting for Gah Lak Tus, eventually unveiling himself with his superior officer Yahn-Rgg unleashed a Killform on Cape Canaveral, and sided with SHIELD in fighting the World Destroyer.
- Adapted Out: Marh-Vell's connection to Rick Jones, his rivalry with his superior over Una, his possession of the Nega-Bands... none of those occur for this version.
- Arm Cannon: His armour comes with a "Uniband Totalkannon", which while so small it doesn't even look like a weapon, packs a punch big enough to fry a killform at full power.
- Back for the Dead: After being criminally underused throughout Ultimate Marvel's run, he returned in Hunger. Where he died.
- Body Horror: The surgery required to make him look more human gets undone by Yahn-Rgg remotely. It's not at all pleasant for Marh.
- Commuting on a Bus: Usually made brief cameo appearances after Ultimate Secret, along with a supporting role in Ultimate Doom. But that was about it.
- Deadpan Snarker: Since his creator is Warren Ellis, he's incredibly snarky. Taken even further by Brian Bendis during Ultimate Enemy, to the extent that Wendell Vaughn notes it's seriously annoying.
- Genuis Bruiser: Even by Kree standards, Marh knows his stuff. In fact, as he tells Yahn-Rgg during their confrontation, he knows their ship better than Yahn does. And Yahn's the captain.
- Intrigued by Humanity: He takes a fondness for us. And things like Krispy Kreme donuts and Lost. So he decides to try and prevent that whole "destroyed by Gah Lak Tus" thing.
- It Is Pronounced Tropay: Nick Fury winds up calling him "Marvel" because that is what his name sounds like. Only a few, like Thor, take the effort to actually try and pronounce it properly.
- Obfuscating Stupidity: As Dr. Phillip Lawson, he pretends to be a slightly ditzy human scientist, who makes a comment about admiring "her" (meaning a NASA ship he designed) rather than Carol Danvers, who's standing in front of him. Plus, pretending to be a human means having to dumb down a little anyway.
- Race Lift: Goes from being a pink-skinned Kree to blue.
- Starfish Aliens: The Ultimate Kree look less human than their Earth-616 counterparts. Marh had to undergo extensive surgery to even look remotely human
- Still Wearing The Old Team Colours: Even after defecting, he remains in his Kree uniform. It helps that it looks like a superhero uniform.
- What Measure Is a Non-Human?: Hawkeye for his part doesn't consider Marh, or the Kree in general, to be people. Even after siding with Earth, they still don't trust the man, and when it looks like he's turned on them thanks to Reed Richards, Nick Fury drags him to a basement to interrogate him.
Carol DanversInitially the head of security for Cape Canaveral, Carol Danvers was the one who questioned Marh-Vehl after his defection. Some time later, when Nick Fury was ousted from SHIELD, she was made Director in his place. Somehow. For no adequately explained reason. She didn't do terrifically well, and was eventually removed and replaced with a restored Nick Fury after the death of Spider-Man.
- Badass Normal: Despite her string of bad decisions, Carol is at least capable of surviving around Norman Osborn, and unlike her regular Marvel counterpart she never gains any superpowers.
- Deadpan Snarker: When written by Warren Ellis, at least. Not so much when written by Bendis or Loeb.Nick Fury: Isn't [preparing to fight the Kree] fun?Danvers: I'll be outside shooting myself in the head, general.
- Most Common Superpower: Not at first, when she had normal human proportions, and not when in Ultimate Spider-Man, but played ludicrously straight during Ultimatum.
- Nice Job Breaking It, Hero!: During Ultimate Spider-Man. Over and over and over. For example: Attacking and antagonising Spider-Man when Norman Osborn escapes his cell, rather than just asking for help, futzing with his webs-shooter so that Peter runs out of web fluid at a critical moment (and would have become street pizza if not for Shadowcat), and when Norman gets better from being killed, she... just locks him back up in the same cell he previously escaped from, allowing him to, surprise surprise, escape again. In the exact same way.
- Power Hair: Her initial look in Ultimate Galactus. She grows it out on joining SHIELD.
- Properly Paranoid: Carol never trusted Phillip Lawson because she thought he was a flake. Turning out to be an alien spy sent to watch humanity die did not improve her opinion of him at all.
- Reality Ensues: Carol Danvers is an air-force colonel, with no apparent background in spy-works, intelligence or dealing with the superpowered community. When she's made head of SHIELD, she's terrible at it.
- Slasher Smile: She looks... way too enthusiastic about the idea of handing Marh over to SHIELD's hands for interrogation and dissection.
- Took a Level in Dumbass: On being put in charge of SHIELD.
