Megatorn was originally an autobot during the Galatic Civil War and was destroyed by Luke Skywalker on Yavin 4. He was the master of the Sith and ruled over the Emperor himself. Later in his life, he met Optimus Prime and the confilct between them began. He died by Luke Skywalker's lightsaber as it drove through his circuts and exploded. He was a great commander and tried to defeat the Jedi scum once and for all, but he failed (loser). he was a fool to think he could defeat him in battle. Luke severed his fingers and his "part" of the machine. (the part that is directly underneath your stomach) he screamed in pain as he withered away, only to be stabbed by Luke.
