Slifer the Sky Dragon

 Origin: 

In ancient Egypt, on the planet, Nessa, the Pharaoh Atem resurrected Slifer from the lost spirit of the Skorcher, Osiris. Atem commanded these spirits to serve him, and only those powerful enough to contain their power. Slifer, along with Obelisk, and Ra, were all Atem's powerful spirits. Once Atem was killed by the hand of his father, Trident, the three spirits were separated across the universe, to other temples with powerful magical enchantments. Slifer was sent to the Sandworld and was sealed in the Sorcerer's Circle. The Sorcerer's Circle contained powerful and important knowledge of the Egyptians, and Slifer was to guard the knowledge and prevent any unworthy to enter its realm.
