I know ASB RPG introduced a created pokemon into their set up, but that's going to much into the realm or RPG to be implemented here. As for legendaries, it would be far to powerful and overpowering to give to one person. Chris did have an idea about tournament prizes at one point, that we could theoretically implement into a prize, I'll have to discuss it with him first.

On a side note, I would love to have some kind of mini-tourney where each member is given a random legendary to battle with, just for fun.
