Lord High Protector

Lord High Protector was a title given to Megatron. It is one of two rulers of the planet Cybertron, the other being the Prime, a title held by his best friend and comrade, Optimus Prime. The Lord High Protector is a military title, and Megatron oversaw the armies of Cybertron while Optimus Prime was the civilian and spiritual leader. Together, both of them stewarded the All Spark. However Megatron's military command led to a dangerous imbalance of power when he came to covet the life-giving artifact and formed the Decepticon.
