@supernova7005: He was useless because he was drained from practicing the Ma Fu Ba technique and getting his butt kicked by Drum. When he saved Goku from the first big blast that Piccolo sent he collapsed from exhaustion. Also, yeah being drained quite a bit would reduce their power down quite a bit. One more thing: while I know you're fighting about Muten Roshi being a moon buster acting like 23rd Tenkaichi Goku isn't one is pushing too far. Piccolo was only a little stronger without the weighted clothes when he blew up the moon than he was at this time. However he only used a basic blast to do it and with his weighted clothes on. If he used a special powerful technique to do it that would be one thing but acting like Piccolo with his power suppressed has more power with a basic blast than a super kamehameha from Goku during this tournament is a shaky argument to say the least.
