Squirrel Girl (http://en.wikipedia.org/wiki/Squirrel_Girl)oh god squirrel girl. i almost forgot about her
She's defeated people such as Deadpool (http://en.wikipedia.org/wiki/Deadpool) (Immortal and utterly insane psychopath with ridiculous healing), Wolverine (http://en.wikipedia.org/wiki/Wolverine_(comics)) (Pretty much indestructible with ridiculous healing), Thanos (http://en.wikipedia.org/wiki/Thanos) (That dude who it took like, pretty much everyone in the Marvel universe to defeat, he's pretty much a god).
Squirrel girl gives no fucks.
Other than that, I like the representation of Iron Man and all his tech in the recent movies.
Only hero I actively dislike is Superman, he's so boring.
nightwing for sure
some of my friends actually call me that, im not sure why
hes also my strongest character in Injustice for those who know what im talking about
Honestly I hate Injustice :/ I never did like fighting games with the "hold back to block" system because I feel it just doesn't work. Also, like claw said, pay to win. Grab scorpion and abuse the block system with his teleport. I just feel like they did a better job with mk9.never said it was my favorite game :P
