Mecha Tyranno-Zilla is a mostly-metallic version of the Zilliesey tanterous, nicknamed Tyrannic Zilla. Even after it was revived by the G.D.F., it only trusted Keen, the youngest scientist in the real world (the youngest counting every universe, is Dexter). It's favorite color is yellow. It has energy-generating spikes on it's back, it can also fire atomic blasts, it can think, it breathes in and out of water, has teeth with Godzilla's strength, and has red skin.
MT-Z used to be a preserved Tyrannic Zilla body before being revived by the Global Defence Force, the first face it saw was Keen Lebron's. He thought he was his father, and so that is why he trusts Keen. The Global Defence Force would not allow Keen to take MT-Z, but MT-Z threatened to destroy the place, of course, they tried to destroy/deactivate/obliterate him, and made him angry! Keen convinced the GDF to stop trying to deactivate him, and they let Keen put him in any deserted place in the world, and Keen chose the lake where he was found.
- Tyrannic Zilla was unknown to even exist until MTZ's corpse was discovered.
