Roshi would rule. So would tien. But yamcha would be terrible.. I mean what can he do? Wolf fang fist, kamehameha, and that super controllable ki ball. That's about it :/ he has no significant role throughout the series, he's a total coward and just gets the crap kicked out of him on the rare occasion he puts a shakey foot forward. Krillin's way more courageous than him
And tien even more; Krillin always bravely rushes in, and gets beaten up, and then the evil dude makes some remark about how his head bounces. But we like krillin for the effort. But TIEN, whenever he steps in, he always gets in one good smackdown on the badguy, no matter how weak tien is in comparison. Kills a saibaman and blasts nappa pretty badly in the saiyan saga. Keeps cell at bay in the cell saga. saves gohan in the buu saga. come on
If it weren't for tien, who knows what woulda happened in the saiyan saga. And in the cell saga piccolo would have been killed, and gohan killed in the buu saga! Ok gohan died anyway, and if he wasnt absorbed, goku probobly could have owned buu, but that's beside the point. TIEN ROOLS.
