A wonderful reference sheet I got from  xenonnero oh probably my main OC and Fursona that i've been stuck in a workshopping hell for a while now.

Meet Shinra Redgrave; a wolf that enjoys the company of others and has a spring of optimism within him and is always down for having some fun good times with others and always puts up a smile on his face. While he's playful with his fellow bros he likes to spill that into his biggest hobby as a professional fighter, be it MMA, Pro Wrestling, even just a street brawl you'll find him trying to join in on the fun or be up in the front of the sidelines cheering the fight on. It really gets his blood pumping and he lives off the thrill of it so much that he's become tenacious because of it, if you don't put him down then he's just going to keep coming back up again and again till you do. Even then he won't hold it against you, he's somewhat aware of his love for it and how it can really be a bit self destructive, he still wouldn't give it up for anything else.

He's pretty good nature at heart as well which explains his good sportsmanship. Living life to the fullest and sharing that with people is something he believes everyone should get in on and even if they don't see it that way he isn't going to just let someone sit around and muck about because of it, he's going to try and help them have a little bit of fun even if it means getting away from the big crowd. Circling back to good nature and sportsmanship he's also been known to insert himself into situations between people if he thinks things are being unfair in some form or another, intervening with his fists if need be.

Its probably due to him enjoying superheroes as a kid and even into adulthood he still revisits those kind of stories from time to time, tokusatsu shows being a big influence on both his morales and general love of martial arts as well.
