Megatron is the main later central antagonist in Transformers: Cyberverse.
Megatron was once a gladiator and miner in the arena back on Cybertron. He was also pretty successful and decides to take power for himself as a politian and using it to improve Cybertron's system of power. How ever he was slowly and slowly becoming more corrupt and he was friends with Optimus Prime before Megatron's lust for power drove them apart. Megatron would lead the Decepticons and go for War against Optimus and the Autobots for the control of the Allspark which caused damage to the planet Cybertron and Optimus to the Allspark and hid it on earth where it was guarded by Cheetoh.
