Ultra Magnus!
Fiction
Marvel The Transformers comics
The Jekka Amphitheatre was located in the Decepticon stronghold of Tyrest. It was once used as a venue for the prestigious State Games but following the outbreak of war it fell into vorns of disuse until it was reopened by an alliance between the alien Zabra and the Firecons. The ongoing war allowed the Decepticons to provide Zabra with a ready supply of prisoners (including the hapless Chameleon) to pit against his champion Hooligan, while Zabra's offworld audience offered the Decepticons a stream of commerce and income.
When Ultra Magnus and the Sparkler Mini-Bots ventured into Tyrest to investigate Chameleon's disappearance, they stumbled upon this operation (along with Chameleon's arm). They were quickly captured by Zabra, who held the Sparkabots hostage while forcing Magnus to fight Hooligan in the arena. Filled with righteous fury, Magnus made short work of both Hooligan and Zabra, exhorting the audience to turn away from this kind of violent entertainment and to live better lives. His words seemingly had little impact. Deadly Games!
