Episode Summary

As Tails heads off to retrieve the X-Tornado, E-102 Gamma engages in serious introspection. Recalling Amy's kindness towards him, and the cruel treatment his fellow E-series robots suffered under Eggman, he decides not to obey Eggman any longer and resolves to save his teammates.

Meanwhile, Sonic encounters the spirit of Tikal, who leads him into the Lost World ruins. Sonic sees the carving depicting Perfect Chaos and experiences a flashback to the destruction of the Master Emerald shrine. Once back outside, he sees Eggman fly past and follows him into his Final Egg base. Inside, he encounters Eggman and fights against the Egg Viper. The Viper is destroyed, along with Final Egg, but Eggman escapes.

Amy and Lily set off for the Egg Carrier to free Lily's family. Gamma, having defeated and shut down Delta and Epsilon, also returns to the Egg Carrier, reasoning that his remaining siblings must be there. On the Egg Carrier, Amy runs into Decoe, Bocoe, and ZERO, but runs into a control room and locks the door before they can catch her. Examining the screens there, she sees that Lily's siblings are inside Gamma and Beta. As she fights her way back out, Gamma shuts down Zeta and confronts Beta, who puts up a challenging fight. Amy finds the robots fighting and urges them to stop, but Gamma defeats Beta at that very moment.

Although Beta explodes upon death, the bird at his core is released unharmed. Gamma then considers his mission complete and self-terminates, releasing his own bird. Lily reunites with her family, and Amy thanks Gamma, reflecting that he and his brothers are now together again.

As Eggman fumes over his latest defeat, he encounters Chaos. Chaos' arrival, combined with the gathering thunderstorm in progress, ends the episode on an ominous note.
