Okay, while he seems fine as-is, I'm just a bit wary of the ability for Saiyans to grow more powerful every time they end up near death.

I'm not very familiar with actual canon DBZ, but I know that's something they can do, and that power levels get to "blow up planets easily" level. I'd like to avoid stuff like that.

In a game with characters from Touhou, Fate, Diebuster, Umineko, etc, I don't see it being a problem.
