After Enerjak's destruction of New Megaopolis and all his Badnik forces, Eggman was forced to retreat into the EggDome for cover, but left a short while later in response to Lien-Da who contacted him for an alliance to replace his troops in return for him restoring their cybernetics. Eggman agreed, but Lien-Da was not made Grandmaster as she hoped. That position had already been filled by Dimitri as he proposed an alliance to Eggman first, therefore, winning the rank. Eggman also made sure they didn't rebel against him by placing bombs in the cybernetics he provided them with. (StH: #183, #184, #192)
