I never read much of anything Ultimate, or much at all with Quicksilver in it, but in 80s and 90s comics I don't really remember him being a hipster faggot. He was a bit of a whiny bitch, that's for sure, but hipster? Maybe I'm just not familiar with what they've done with him the past two decades, because he looked nothing like that from what I remember.
This picture below is how I always pictured him. However, given that I had to wade through hundreds of more current pictures of him where he did indeed look like a douche, I guess you guys are right, and I'm just old. He was never a great character, but why would they make him even more annoying?
