I sincerely hate to mention this, even though I kinda like the character conceptually, but that reminds me of someone else a little bit more than Super Saiyans.
Diana the Hedgehog probably exists out there too, now that I regrettably think about it.
Uru's special and all, but it's not unstoppable and it's not unbreakable. Though hell if I'm doing the math to see what kind of force you need to break something compacted by the gravity of a dying star, I don't feel that's a game changer in of itself. The axe Jarmborn is a good bonus for Thor, though. Which brings me back to some of Diana's more ludicrous weaknesses that come from breaking her toys. I mean, it took Superman to break the lasso, but if this axe can cut through anything, it's a safe bet it'll do the job as well. So now I'm a little conflicted on how much use Thor can make out of that axe.
Eh. I'm still voting Wonder Woman.
