Sonic Mania
In Sonic Mania, after Sonic and Tails had defeated Eggman, the evil scientist detected a strong energy source coming from Angel Island, prompting him to send his five elite Egg-Robos, the "Hard Boiled Heavies", to go and retrieve the source. Soon, Eggman found himself in Green Hill Zone, where he faced Sonic, Tails and Knuckles in his Death Egg Robot. He was soon defeated though, and eventually came across his newly upgraded Hard Boiled Heavies. Seeing as the Heavies would no longer listen to him, Eggman stole the energy source, the "Phantom Ruby", away from them and used its power to send Sonic, Tails and Knuckles, who were eavesdropping on him nearby, away.

Over the next period, Eggman used the ruby to restore Little Planet to its mechanized state. There, he built a robotic fortress known as the Titanic Monarch. Along the way, Eggman made several attempts to stop Sonic and co., but was defeated each time. He would also use the ruby to displace the heroes at different places in space-time.

It was not long until Sonic, Tails and Knuckles chased Eggman down to his base. However, the mad doctor was prepared for them. He fought the trio using his Phantom Egg while sending the heroes to also fight the members of the Phantom Heavies. Unfortunately for Eggman, he was still defeated. Upon his defeat however, the Phantom Ruby sent Eggman and Sonic to an unknown location. There, the Phantom King (the upgraded leader of the Hard Boiled Heavies, the Heavy King), stole the ruby for himself. Eggman was not prepared to give up easily though, and used his Klepto Mobile to combat his traitorous minion. In response, Sonic used the Chaos Emeralds to transform into Super Sonic to fight them both. After the Phantom King was defeated, Eggman was delivered the final blow by Super Sonic, putting his mech and his plans to ruins.
