I think Bigger Brother and Firestorm will have no trouble in melee 2 (they have lower ground clearances and the other two have self-righting trouble) so expect it to be over quickly, but in melee 1 anyone could go through - as King B and Pussycat are very slippery and difficult to finish off, Behemoth is good but has self-righting trouble and Dantomkias ground clearance on the sides leaves it open to attack from anything. Expect all 4 robots to survive and the judges to decide.

I still think Firestorm will win though. (unless Chriss Firestorm will not win comments are a spoiler in disguise)
