I'd still say he's iffy... Surviving from geting hit by Cyborg isn't anywhere near the caps either way. For tourney purposes, he can't use hard light constructs. One could make a case that he could based on that one scan, but that's all that side would have. And if Khell chooses to argue that way, TOAA will find some painful way for Dr. Light to die and be permenantly removed from the tournament. Pirating energy isn't banned either. Wondergirl's actually IN this tourney, and Light didn't do anything like physically overpowering Superboy. Again, he's never teleported anyone, and he didn't use it in battle. For tourney purposes, the tactic wouldn't be possible.
I think he's borderline, but still acceptable. If Khell hypes him up too much, he gets squished. God damn, I love TOAA...
