Snively continued to operate as Eggman's agent when the Knothole Freedom Fighters rose to oppose, even aiding in his operations on Angel Island later on by piloting an Eggrobo. Among his other accomplishments were the creation of the Chemical Plant Zone. When Eggman's plans with the Death Egg failed, Snively took matters into his own hands by trying to obtain the Master Emerald from its lone guardian with the aid of a Mecha Sonic. But once again, the odds were against him, and he eventually made his way back to G.U.N. claiming that he'd been spying on the doctor in their behalf. He would also claim that he had remained at Eggman's side so long in an effort to keep his armies under supervision. (SSD: #12; SU: #70)
