Fiction

Marvel Comics UK continuity

Trannis seized control of the Decepticon army after Megatron's crew became lost on Earth. He conquered most of Cybertron, but the Autobots held their fortified capital of Iacon for hundreds of thousands of years until Trannis decided it wasn't worth taking, so he razed it instead. At that point, all of the Council of Autobot Elders except Emirate Xaaron surrendered to him. Trannis immediately had them killed. Emirate Xaaron escaped to form an underground resistance.

Trannis eventually became complacent in his rule and fell out of favor among some of the Decepticons. The Decepticon high command made plans to get rid of him, but the Wreckers beat them to the punch when they assassinated him.

He was succeeded by Straxus. Cybertron: The Middle Years!
