Dblade, your character looks fine so far. I'm in the process of creating a CS for Pariah, this Universe's premier Batman-type but Strix is actually much different. Super-intelligence would probably be reserved for full-on Scientific heroes and muscle mimicry seems like it could be abused to easily solve problems. If you wish you could choose to have enhanced agility or reflexes or some-such but it is not required. 

In your full sheet, you'll have to explain why he trained in martial arts and how he attained his aptitude for criminology and inventing along with his motivations for learning any of those. 

Shanks, your basic character sheet has a few surface flaws that aren't much by themselves but taken together aren't quite up to snuff. First off I don't know why a native in Canada would have a japanese name, that just seems like you put that there to have a 'cool' name. If you want to have a native character, use a name that an aboriginal of Canada would have. Also Wahaya is the Cherokee name for a wolf so that doesn't really make sense. If you want to have a native character you gotta specify what tribe that character is from and be consistent with it. He also probably wouldn't be blond. 

The idea that the US comes to him to train their soldiers seems like that's shoehorned in and doesn't make any sense. That detail can be omitted and nothing would really change. Keep in mind that he'll be fighting pretty formidable enemies and he probably shouldn't survive any one of those enemies since very few rely on only melee weapons. If he's supposed to be a fusion of the old ways and the modern world, equip him with more modern equipment so that he could plausibly survive. You'll have to more fully explain tactical insight and what that lets him do. And it seems like if he has some kind of "spirit" powers, you could get a lot more traction from those but that's just a suggestion. A spiritual bound to a wolf would also count as a power. 

Also keep in mind that almost no Native tribes live the same way they did hundreds of years ago. They all are pretty much modernized so the idea in your bio that these Natives were entrenched in the 'old ways' comes off as stereotypical. You also have to plausibly describe how he met and befriended a wolf. Just fix those issues in your final sheet and you'll be fine. 

Mat, I assume she's some kind of Spider-Man like hero and so far I am pleased with this haha.

EDIT: Ninja'd by Shanks, but hopefully this answers your question haha. I plan to give feedback on all characters.
