Boba Fett, General Grevious, and Durge battle royal

Falling into a star killed him and the explosion from a thermal detonator is the same process. It vaproizes ANYTHING caught in the blast radius. I'd say that could take him down.

Yeah, at least render him unable to fight, thus winning. If Durge were to fight Greivous, then Boba could vaporize them. The problem is, Durge hates Mandalorians, so he'd probably attack Boba first, and if he used a thermal detonator, they would all die.

I'm still not calling a winner, though.
