The Final Egg is a high-tech-orientated green base. Computer screens and giant light sources decorate the walls. Yellow railing-like patterns and a black wide line with circuit board-like lines inside it stretch across the walls as well. The lower sections of the walls also have computer screens and cylinders with the Eggman Empire's insignia on them attached to them. There are also tube-based work stations.
Battle For Angel Island
After Dr. Eggman had lost his memory and took up a new life as the kindly "Mr. Tinker", Rough the Skunk and Tumble the Skunk kidnapped the doctor from Windmill Village and brought him to the Final Egg. There, Dr. Starline began the process of restoring Eggman's memories. After three sessions however, Starline had failed to make much process with Eggman. This made Rough and Tumble grow impatience with Starline, who had promised that Eggman would make them weapons to use against Sonic. After a damaged Metal Sonic arrived in the Final Egg however, Eggman regained his memories and old personality upon seeing Metal Sonic. Taking control of the assembled group of villains, Eggman was brought up to speed by Starline while repairing Metal Sonic. Introduced to Rough and Tumble as well, Eggman agreed to make them weapons to use against Sonic once he heard that the skunk brothers hated the hedgehog. After hearing about Starline's Warp Topaz as well (which did not interest Eggman), Starline provided Eggman with the seven Chaos Emeralds as his "apprenticeship application". Impressed, Eggman took Starline in as his new lackey.
After reviewing Neo Metal Sonic's past activities in the Final Egg, Eggman went to work on his Metal Virus and assigned Starline to keep Sonic occupied while he got ready. Meanwhile, Eggman sorted out a misunderstanding Rough and Tumble had about their weapon schematics.
While Eggman worked on his Metal Virus, Starline would report that he had baited Sonic and Tails to Windmill Village with a letter, as Eggman had instructed. Although Starline wondered why they had to use such overt means of luring Sonic into a trap when an ambush would suffice, Eggman assured him it would mess with Sonic as Starline wanted. Immediately after, he and Starline began experimenting with the Metal Virus. After a couple of tests, Eggman declared his Metal Virus a succes. This made Starline express happiness over their collaboration, which let Eggman to ask Starline of how he located him in Windmill Village. Explaining that he used the Warp Topaz for that, Starline used it to provide Eggman with a "window" to the site of Sonic and Tails battle with Rough and Tumble. When Rough and Tumble stood to loose though, Eggman began implementing the Metal Virus for the next phase of his plan although Starline thought it was too early. When Rough and Tumble later asked Eggman for another chance to fight Sonic, Metal Sonic stepped in to receive that honor. However, Starline requested to be next to fight Sonic, believing he knew exactly how to hit him.
After noticing his Metal Virus's slow infection rate, Eggman conducted an experiment to see if there was a way to accelerate the infection. Discovering that the infection accelerated the more a victim was exposed to an infected victim, Eggman was satisfied enough with his Metal Virus to properly prepare the next phase of his plan. It was then that Rough and Tumble came and demanded that Eggman gave them a new edge to achieve revenge on Sonic with. In response, Eggman told them his "latest weapon just got out of beta". Later, after trying to kill Sonic with a bomb, Starline made a portal back to the Final Egg, only for Eggman to angrily pull him through the portal and tell him that Sonic was his to kill and that simply destroying him was not unsatisfying to him. After Starline apologized, Eggman let him go and checked the video feed from the bomb site. As Eggman had suspected, Sonic survived the explosion. Eggman then asked Starline why he saved his "obsolete junk" at the bomb site, to which Starline explained that they were collectibles to him. Allowing this, Eggman asked Starline of his impression of Sonic, to which Starline said that the experience had "put a lot of things into a new perspective."
Later on, Dr. Eggman, Orbot and Cubot were preparing special backpacks filled with the Metal Virus when Starline informed Eggman that Sonic and Amy had broken into the base in Echo Mine. Eggman thus had Cubot bring Rough and Tumble to hangar three so he could send them after Sonic and Amy. There, the doctor equipped the skunk brothers with his backpacks, but chose not to reveal the consequences of their usage. He also provided them with a tank. Later, Eggman and Starline watched Sonic and Amy fight Rough and Tumble via surveillance transmitted to the Final Egg. After they saw Sonic get infected with the Metal Virus, they decided to move onto the next phase of Eggman's plan and share the Metal Virus with the world. Soon after, the Badnik work force finished building the Faceship in the Final Egg's hangar. With the Faceship completed, Eggman, Starline, Orbot and Cubot got onboard the vessel and left the Final Egg in it.
