I reckon this could work out fairly well, as long as you keep Oolong himself fairly...well, crap. It could work out better if Oolong didn't get some massive pl after transforming back, but his pl only raises by however much he gained as the other character. Naturally whatever pl he gains as Oolong will be added to the transformed character.
For example(cos I'm bad at explaining things):
Begins with:
- Pl of 100-500,whatever.
- Hp of 30ish.
- Melee capabilities.
Tranforms to whoever:
- That characters pl.
- HALF their Hp, not all.
- All that characters techniques.
And as for dishing out the pl he gains...
Say Oolong transforms into Goku, he gets Goku's starting pl. Whatever amount of pl he gains in the time that he's in Gokus form, be it 20,000 or a million(somehow), he gets that added to his base pl when he transforms back to Oolong.
- Oolong transforms to Goku = 100pl to 700,000pl(I think?).
- Oolong as Goku gets his Pl to 750,000 and tranforms back to Oolong.
- Oolong now has a base Pl of 50,100.
Hopefully now you get the idea. If there's any questions ask, but please don't call it stupid without stating why. Ravendust usually thinks up great ideas, this being no different.
