If that's not allowed, then Henry Jones Jr, who knows you always have to punch Nazis.
Horza from Iain M. Banks' Consider Phlebas (not sure if that's cheating since his full name is Bora Horza Gobuchul, but I'm not sure if the naming convention of the Changers is ever explained, and he goes by Horza). His morality is rather dubious throughout (we had long discussions about whether he was or was not, in fact, a git). However the idea of someone fighting a society in the thrall of AI overlords has taken on fresh meaning lately.

@ami_angelwings The time travel #FavCharacterAtoZ individual really needs to be Homura Akemi, from Madoka Magica. The other H's I can think of don't warp time nearly so much.
I shall claim I don't make the rules, I just work here. #FavCharacterH
Heath from Lonely Monster and Blind Girl, aka the protagonist of my favorite yuri manga. It's about... well, a lonely monster and a blind girl. Heath is really self-loathing but she learns to accept herself. I highly recommend this manga but make sure you read the whole thing! There is an officially licensed version but it only includes the first chapters. I don't know why they did that... so you'll have to read the fan translation.
@ami_angelwings Han Solo. Played by the second coolest actor of the era (after Carrie Fisher) and he had it all. The coolest rogue in the galaxy, with the coolest ship and the coolest lines.
Only way Han Solo would have been the second coolest guy in the room, was if Freddy Mercury was in there too.
And as everyone knows, he’s in Star Wars IV-VI. But no more.
