Episode Title:
Robotnik`s Pyramid Scheme.
Episode Description:
Robotnik then heads to ancient Egypt to get the Emerald of Immortality and to ensure Sonic's ancestors never meet so that he'd never be born. Sonic and Tails go after him, prevent Robotnik from interfering with his ancestors' meeting, and then race to the crypt of Robotnik's ancestor Robotnikhotep, where the Emerald is kept. Robotnik successfully obtains the Emerald, but, with help from his ancestors, Sonic steals it back and sends him, Scratch, and Grounder forward in time to a dogfight during World War II.
