I was thinking about a namekian doctor. Uses his Ki to heal like Dende but can also use his Ki to harm. I saw that you didn't have a restriction on Namekians.

Does he have a personal set of dragonballs?  Sounds a bit op, but they can only be used once per year, so it wouldn't have to be.


Just a thought.
