for me it's gotta be Deadpool, he's a guy who's just been absolutely FUCKED by EVERYTHING. Fucked by his circumstances, fucked by his friends, fucked by his enemies, fucked by bad writers, fucked by expectations, fucked by his mind, fucked by himself too.
He's not a good person by any stretch of the imagination but he constantly struggles in a way that is not heroic because he has a noble heart or any of that, it's because in a literal sense you cannot kill this guy: He IS the cancer, so might as well keep going even when there's no hope, if all there is to life is suffering, then let's suffer on and try to make light of it, the audience might enjoy it.
He also is a fan of Captain America and so am I so there's that.
>>149124929Is it because he is "strongest there is"?
