Normally I would point out that Dazzler could easily overpower Jubilee, but a simple fact makes that totally untrue. You pick a fight with Jubilee, especially if you hurt her, you picked a fight with Wolvie. And he would lay a smack down on Dazzler so fast. So you can't take her on with out taking on half the X-men. From what I read Dazzler didn't bond half as well with them so..... XD
Jubes was a bit of a snot to people she didn't like, but hey, she got that from living on the street for a time. But in Gen X is where she really got to shine. Of course that is where the real snot showed up....M is a REAL bitch. Last thing I saw of Dazzler is that she was all over Longshot. But looking at X Factor Investigations, I guess that ship has sailed.
what we talking? in a fight? looks? or better character? well in a fight jube's dont even have her powers no more and even if she did dazzler is more powerfull, so dazzler. looks, hands down dazzler.character wise jubes may take that one for the fact that i have read better stories with her..
