Would the Ultimate version of Dazzler count?

I'm going with Gambit becuase he's a rogue, but he's an honorable one. I think that his hard upbringing makes me think of a street punk type. Think of a an hornorable thief that always has his friend's backs. I'm really hoping that he shows up in the next movie.

In looks and attitude....you could include Storm.
she sported an Mohawk and leather duds after she lost her mutant powers and began hanging out with Yuriko.

She adopted a "Devil may Care" attitude and lived on the edge.
She came back to the Xmen and challenged Scott (Cyclops) to duel over leadership of the Xmen.

With no powers of her own, she single handedly kicks his ass. (even thought he was allowed to use his).

Don't forget Cannonball of the New Mutants and his girlfriend, Lila Cheney!

rock on...
boom~!

Early Boom-Boom from Secret Wars II up until she joined the New Mutants was kind of street punk.

Rictor from X-Factor until the end of New Mutants had a punk style going on (mohawk, leather vest, gloves).

Storm in the 80's was sporting the mohawk and leather as previously mentioned.

Callisto also had a thing for leather and chains..and knife fights and gutter filth....

Chamber in Generation X comes close but his look was more goth than punk.

I was never clear on what genre of music Lila Cheney played, but her look in most of her 80's and early 90's appearances was glam punk.

That's about all I can think of right now.
