I mean, the whole "no weapons" thing is kinda bullshit - you´d have to exclude the robot guy per se, because his body definitely has been modified due to his existential nature lol.
And Piccolo just gave his worst fight ever. Seriously, you can only do this dumb focus move?! Since he was able to block all of Freezer´s close-combat attacks with only one hand, surely Piccolo would have had other means to incorporate in this battle.
Oh well, looking forward to Vegeta. This tournament seems to be a set up to let him shine for once. He should easily win against Freezer. Also win against the robot, because there HAS to be a confrontation between Vegeta and the 6th universe saiyajin boy. Don´t see how Vegeta could lose to a saiyajin who doesn´t know about super saiyajin transformations, which means Vegeta will probably lose to Cooler, who then is finished of by nipple-guy.
