Sonic the Hedgehog 4: Episode II
Eventually, Eggman had a showdown with Sonic onboard his E.G.G. Station, only for the hedgehog to destroy his Egg Destroyer Battlesuit, along with the station. With the return of the Little Planet however, Eggman set out to defeat Sonic once and for all by salvaging Metal Sonic.
Eggman later constructed a powerful fleet of spaceships to attack the planet and was confronted by Super Sonic, but revealed that it had all been a trap. He was able to drain Super Sonic's energy and use it to shatter the planet into several large fragments in his bid to release a powerful creature, but ended up transforming Sonic into the Werehog as a result. Terrified, Eggman had him removed from the ship.
In spite of Metal Sonic's past failures, Eggman gave his mechanical minion another chance during the Olympics. After capturing Sonic's various friends using booby-trapped equipment, Orbot and Cubot, and his Caterkiller robots, Eggman challenged Sonic to defeat Metal Sonic in order to save his friends. However, Sonic managed to achieve victory by channeling the spirit of the Olympics, and forced Eggman to flee.
