Lol I was late to the 15th man project

You know, I really like this character! Sounds like a very cool premise, being Leo's rival and having a polar opposite kind of disposition. I dig that very much, it would be a nice addition to the story and would create some nice character interaction between him and Leo, if Leo is still alive when you can get him. Or even some nice flashback events after Leo has died, with him and Leo trying to outdue each other in training, or whatever else.

The only thing I would like different, is this:
Theme Music- Use Boss Battle ie. Atma Weapon Fight music.

I would have him with some sinister imperial death march sounding shit ;p

Nice character conception!
