Thanks for asking! I’ve only seen the X-Men movies, I haven’t read the comics, so this isn’t as informed as it might be…
Favorite Female: Eesh… probably Raven a.k.a. Mystique, in both the older and the newer movies, but they don’t manage to make the female characters very likable… Unless the Deadpool movies count, in which case Domino. Or maybe Laura from Logan.
Favorite Male: Erik Lehnsherr a.k.a. Magneto
3 Other Favorite Characters: Charles Xavier~Professor X, Peter Maximoff~Quicksilver, Logan~Wolverine (not very original, I know)
3 OTPs: Cherik (Charles/Erik) is #1, obviously. (Isn’t it a contradiction in terms to have more than one OTP, since it stands for “One True Pairing”?) Erik/Raven is also good as a temporary ship (I imagine that Erik regards her as simultaneously a stand-in for, the opposite of, and a fuck-you to Charles). But Hank/Raven is cute, too. And rebound Charles/Hank (again, temporary). Uh oh, that’s 4.
Notp: I don’t totally hate Charles/Moira in principle, but the way it was handled in the movies was just appalling. Moira’s presence in Apocalypse felt like a massive “no homo” sign.
Funniest character: Quicksilver, in DoFP. In the Deadpool movies, probably Blind Al. In the older movies… no one was funny.
Prettiest character: James McAvoy as Charles Xavier (I hesitate to call Michael Fassbender “pretty”)
Most Annoying Character: I’m not a fan of either Summers brother. Or Sophie Turner as Jean Grey in Apocalypse. (I’m not a fan of that movie in general.)
Most badass character: Probably Storm. She controls the weather, FFS.
Character I’d like as my BFF: Can I say Domino? Yeah, Deadpool has X-Men in it. Or Negasonic Teenage Warhead, what a name.
Female Character I’d Marry: Domino
Male Character I’d Marry: Oh jeez, they’re all so dysfunctional… I guess Bobby (Iceman) isn’t terrible.
Character I hate/dislike/least like: I don’t know if I really hated any characters (though see “most annoying” answer), but I definitely feel like there were a lot of wasted opportunities, especially with female characters in the new movies. Moira McTaggart was kind of a cipher/shoehorned-in het love interest; Emma Frost could have been way cooler; we could have spent more time exploring Angel and her decision to join the bad guys in First Class; Psylocke and Storm could have been characters, period. And then there’s Darwin, who should not have died. WTF, killing the token Black character.
