For a fanfic multiverse I'm working on, one world is home to Gen 13.  With each world, I try to match its inhabitants to others (e.g., Roger Smith from Big O is his world's Bruce Wayne). I was wondering (in your humble opinions) which DC/Marvel characters would be counterparts to the members of Gen 13. I already have the obvious ones: 
Fairchild-She-Hulk 
Burnout-Firestorm or the Human Torch 
Rainmaker-Storm  
Lynch-King Faraday
 
Grunge and Roxy are the two that confuse me the most. Little help with them?

Roxy- Jubilee
Grunge- Mondo

or maybe Absorbing Man for Grunge to keep from using 2 Generation X kids but I think that Mondo's personality is a closer match to Grunge's

@danhimself: 
Anybody of the DC side?
