[@Kitsune]I don't think making him physically weak would balance the character. The character is balanced by having psionics in the first place to supplement him not ever going to use energy attacks.

Hm...I guess since humans even have a frail ki signature like the farmer when Raditz first went to earth, then I see how there would be one even if it is weak. But I said "None" for the Aura business beecause he won't have one. Because he doesn't expel ki.

Also, he isn't a walking ki battery. If he's using ki empowerment, then he's using it. If not, then he's not using it. Much like how the body eats food, uses the energy, and then requires more to sustain. Energy cycle.
