And that version of Red She-Hulk does not have much more besides her strenght which was strong enough to destroy a planet, when she collided with World Breaker Hulk.
Strenght alone is not enough in such fights. That's the reason why Hulk loses most of his fights to Superman, since he simply lacks the versatility.
It probably would be out of character for Supergirl to use her Heat Vision to cut through Red She-Hulk, but I actually see it being possible, if she is really forced to and even if she simply manages to cut Red's legs off, it should be more then enough to immobilize her even more and render her useless.
And I'm sure there are more then enough DC fanboys outthere, who would even try to argue that Supergirl is physically strong enough to take Red's punches and also destroy a planet while punching someone too :-7
I don't even want to imagine this fight on Comicvine. That would be a pure, ridiculous DC fanwank fest.
"Kara wins, eheheh"
"Kara solos, ehehe"
"Kara easily, ehehehehe"
"I call the characters by their real names, because I think I'm one of their friends, ehehe"
And Wonder Girl went toe on toe with Superboy-Prime and had the upperhand. Does that mean that Wonder Girl now can do what Superboy-Prime did in the past? I don't think so.
Comic writers are stupid. They may have good, or hell maybe even very good ideas from time to time, but most of the time they come up with bullshit ... and in my opinion DC is on the top of it.
And to this fight. Yeah, I think team 1 wins, because they have the versatility on their side, mainly because of the flight. Additionally to that they have the speed advantage.
Never said she was. Just that the writers sometimes come up with weird fights and Wonder Girl beating the crap out of Superboy-Prime is in my opinion less believable than Supergirl going toe on toe with Ultraman.
