Krillin? Lacking in power? Are we conversing about the same character here. He's probably not as weak as you think.

Going by the anime, he ends up very strong. He at least equal to or stronger than Yamcha, who beat up Olibu wiht realtive ease, who put up a good fight against Pikkon, who defeated Frieza with ease. He's stronger than most people give him credit for (in the anime, at least. In the manga, he's extremely weak).
