Jill Valentine and Nemesis from Resident Evil 3.
Crappy Jill cosplays such as this one are a dime a dozen because it's so easy, and if you get 90% of the costume wrong (like I managed to) everyone still knows who it is.

So, yeah. There are a bajillion things wrong with this picture, haha. XD
But it makes me giggle. Nemmy looks so happy.

I am Jill and my friend

is the Nemmy.
ha he still thinks we're in the caveman age
...but now we know the truth behind why Nemesis was chasing Jill; it is the classic "Beauty and the Beast" story. He became infatuated with Jill the moment he saw her (who wouldn't?), but because of his grotesque appearance, Jill ran away, thinking he meant her harm. He chased her all over Raccoon City, trying to tell her that he wasn't going to hurt her, and he loves her, but all he could say was "S.T.A.R.S."
