Tournament of Champions

The Tournament of Champions was an illegal arena circuit below Kaon in the days before the great war. Megatronus fought many of his gladiatorial victories there.

In fact, Megatronus won so many victories in the Tournament that the rules of combat had to be changed just for him. His opponents were allowed to enter the arena first, then scan and assume any altmode they wished. Megatronus allowed this cowardly way of fighting only because it increased his appearance of invincibility when he inevitably won.
