Arena is a boxing ring
Fight to the death
Verdict: I'm siding with the T-1000 on this one. With liquid metal, he could possibly take any physical attack that Robby uses. And since he has great strength himself, he could hold him off for awhile. Of course, Robby could try and make something to destroy him, but the T-1000 could take being frozen into ice, so he could outlast him.
