An unarmoured Space Marine (40K) replaces Obi-Wan, Anakin and Padme (Star Wars) in the Geonosian coliseum in Attack of the Clones. Can he survive?

He's tied half-naked to a stone column using a steel chain, and three monstrous beasts -- the Reek, the Acklay and the Nexu -- are introduced to the arena to tear him apart in front of the baying crowd.

He receives no outside assistance.

What happens next?
