I'd like to think that it's his ice powers, but there are other people here with ice powers so it's not.
Maybe it's his story, although everyone's fursona's stories are pretty awesome and it's not a trait, just a story.
Maybe it's his ability to speak more languages then there are on Earth (some from other dimensions, some from other planets, it ties into his story though) which reflects how I want to be a polyglot.
That's probably it.
Or maybe it's how I fit my theoriotype into him. He has a spirit-panther dude always with him that guides him and helps him and he can transform into the panther when something insane happens. Also as a completion the panther has fire powers in contrast to the tiger's ice powers.
That reminded me of another interesting trait, he's heavily centered around balance and his life is effectively perfectly balanced, that's a big reflection of my life too -.-
