isn't current supergirl said to be stronger than superman? 😑
if yes, he is stopped dead right there. i do't think it would necessarily be easy getting to that point though . . .
and i agree, he might be able to beat grundy, depending on the version. there's a chance he could go nimrod on juggs and get a win, but i think it's a small chance. i couldn't really see him being stupid enough to LOSE, but that doesn't mean he would win, either . . . i'm surprised those 2 have never really squared off in a book -- least not that i know of.
tough gauntlet.
