Under the tutorship of Sentinel Prime, two brothers were chosen. The two siblings, ruled together and created harmony for all the land. The eldest, Megatron, commanded the defense force to protect all his subjects. The younger, Optimus, was their social and spiritual leader, heading the science division to relearn the secrets of his kingdom’s past. But as time went on, Megatron became resentful, learning of their tutor’s favour for Optimus. One fateful day, Optimus found a mysterious object of immense power. Megatron, sensing a chance to outshine his brother, took possession of the artifact. But the artifact would one day consume and possess him, using his jealousy to corrupt him, transforming Megatron into a vicious stallion bent on destruction. Optimus, confused and hurt from his brother’s seeming betrayal tried to reason with Megatron, but the power of his new master was too much for the young Prime.
