I'm starting this thread because two posters have recently started claiming that Krillin is the most powerful Human, a belief I disagree with. Sure, I could have argued with them in that other thread, but that would be the wrong place for the debate. Anyway, here are my arguments for why Tien is stronger than Krillin. 1) The power level ratings always list Tien's as being higher than Krillin's. 2) Tien defeated Goku in the tournament in which Tien turned good after Goku had defeated Krillin. 3) In the Namek Saga, the combined efforts of Vegeta, Krillin, and Gohan were no match for Recoome. Tien, on the other hand, was stronger than Jeice and Burter one-on-one. 4) Krillin couldn't even budge Second Form Cell. Tien could at least hold him at bay. 5) Krillin stopped training. Tien didn't.
