He's technically not a bear since his species is not part of the Ursidae family. They just happen to look like them, if I look exactly like Michael Jordan that doesn't mean I'm him or a professional basketball player.

When has technicalities ever stopped anyone from making jokes? :P

Anyways you'll need to review the rules for a missing detail in your notes section. While I realize that a higher gravity on a home planet is a very comic book excuse for a character being stronger on Earth, you do realize that he would get weaker as time went on? If his muscles are used to exercising under the gravity that allows him to lift 50 tonnes, there would be very few things on Earth that would actively allow him to maintain that strength level thus causing his muscles to deteriorate the same way an astronaut's do after spending so much time in zero gravity. A hundred and fifty feet is a little high for jumping but I suppose it's alright since we have people who fly. 

Also while normally I'd knock you marks for explaining your backstory in your sample, it makes sense in this case as otherwise I don't think I'd accept the character. I do have quite a few qualms with the backstory however as Urxas thinks in terms of Earth politics, notable by his use of 'left wing' and what not. Furthermore, isn't the idea of the Ursas kind of stepping on the Green Lantern's toes?  

I have to say I'm very torn on this character. The idea is unique and all, but I almost would have preferred a Were-Bear than this execution. It strikes me as very contrived and unnecessary. To conclude I don't believe that Urxas as he's currently designed is a good fit for this particular RP.
