Our best guesses for who's who in Legion comic characters
Last year, FX premiered its X-Men franchise series Legion, about a mental patient who may actually be the most powerful mutant on the planet. Now in its second season, Legion has proven itself to be more than just your typical comic series. It’s beautiful and strange and completely unafraid to take risks. And it doesn’t set itself up to be a comic series, either. Sure, there are mutants. But it isn’t like we’ll ever see Wolverine in all his yellow and blue spandex glory. In fact, Marvel confirmed only two of Legion’s characters are based on X-Men characters.. The rest have only loose inspiration among existing characters. But with our deductive reasoning skills, we’ve managed to narrow down who exactly we think the Legion comic characters line up with on screen.David Haller

Legion

Amahl Farouk

The Shadow King

Lenny Busker

One of Legion

Syd Barrett

Rogue

Ptonomy Wallace

Mesmero

If we’re considering what Ptonomy can do as a sort of mind control, then it’s pretty easy to see the similarity to Mesmero. The Marvel mutant has the ability to control people in a hypnotic state, which isn’t unlike what Ptonomy does when he decides to put someone to sleep with his mind. Analyzing memories is just a short jump from forcing people to do your bidding.
Cary & Kerry Loudermilk

One’s a middle-aged man. The other’s a girl somewhere between her teens and early 20s. They aren’t just best friends; they actually share a single body. Fun fact: when you expect to give birth to a Native girl and actually give birth to a white boy, the mix-up can cause problems at home. It can also cause problems when it comes to figuring out who gets to drive, so to speak.
Evangeline Whedon

Okay, so Evangeline Whedon actually shape shifts into a giant dragon when she comes into contact with blood, but hear us out here. Like Cary, she’s an intelligent, productive member of society. She and the dragon are two parts of the same whole, like Cary and Kerry. And, like Kerry, the dragon is a fighting powerhouse with superhuman strength. They’re basically the exact same character.
Oliver Bird

Aka the current travel vessel for the Shadow King. Oliver is a powerful telepath (not David-level, but still) who not only has mastery over astral projection and manipulation, but he can also read others’ minds and project his own into theirs. He also has a fantastic sense of style, but that’s a different list entirely.
Exodus

Oliver may be a less advanced version of Exodus, an extremely powerful psionic mutant in the X-Men universe. Their similarities lie in their ability to not only read and control other’s minds, but in their mastery of the astral plane as well. Exodus happens to sport some pretty sweet threads, too.
Walter "The Eye"

Walter isn’t just a telepath. He can also change his appearance to look like any other person. As far as powers go, it isn’t a bad one to have. Especially if you’re working for an evil government force and need to figure out a way to thwart the good guys’ plan while also escaping unharmed.
Jason Wyngarde "Mastermind"

Allegiance to an evil organization? Check. Psionic ability to make others see and hear whatever he wants them to? Double Check. Fancy nickname with psychic overtones? Check, check and check. If Walter “The Eye” wasn’t created to be the TV version of Jason Wyngarde “Mastermind,” then we’ll just drop our nerd card at the door.
Admiral Fukuyama & the Vermillion

Admiral Fukuyama is the cyborg leader of Division 3. At this point, it’s still kind of up in the air whether or not he’s actually on the Summerland mutants’ team, but we’d probably put money down that he isn’t. He speaks through the Vermillion, androgynous androids who manage to be both hilarious and creepy AF at the same time.
Donald Pierce & the Stepford Cuckoos

Donald Pierce is the cyborg leader of the Reavers, a very openly anti-mutant organization, but at least we know where exactly his allegiances lie. Although he doesn’t have anything to the Stepford Cuckoos, it is worth noting the loose similarity between them and the Vermillion. But while the Vermillion only share a psychic connection to Admiral Fukuyama, the Stepford Cuckoos are actual psychics (and powerful ones at that).
Rudy

Poor Rudy only managed to last all of four episodes before biting the dust at the hands of a Division 3 agent. But during those four episodes, we got to see him show off a few amazing skills. While the Legion (and X-Men) universe seems to have an overabundance of telepaths, Rudy had the distinction of being a telekinetic. So he couldn’t infiltrate anyone’s mind, but he sure as hell could use his own to throw a giant boulder at them.
Hellion

Like Rudy, Hellion is a powerful telekinetic who can create destructive blasts with his mind. He’s also kind of a minor character as far as the X-Men go, which, again, is right in line with what we know of our Legion buddy Rudy. Apparently, moving things with your mind just isn’t as well-received of a power as actual mind control.
