Did Krillin have the most potential of any human?

I honestly don't know. If not, who did/does?

That would be oob

Anyways, in terms of the main cast, yes, yes he did

@dbzk1999: Is Uub just a human though?

Even though I believe Krillin was confirmed to be the strongest human (excluding Uub) Tien always seemed superior, or at least in Dragon Ball. Remember how awesome Tien was in the world martial arts tournaments in DB? He was busting out a lot of awesome techniques, including the rival schools Kamehameha wave in one try (iirc), plus he gave Goku the toughest fight he had ever been in up to that point, so I always thought he had the most potential. Lol I wish he stayed awesome :/

Tien did imo, he did the Kamehameha against Master Roshi without even training.

@guru_crack: he's about as human as you can be

He has two human parents, him being a reincarnation doesn't change that (considering nearly everybody in db is a reincarnation)

I would say Tien and I do believe he is the strongest human.... Beside Uub -_-

Yeah I go with tien to he was able to delay cell for a bit with the tri beam
