Chapter 5: Mobius Freed
After Sonic, Sonia, and Manic met back with Aleena, most of Mobius was saved except for the main city of Mobotropolis. To save Mobotropolis, Sonic left his family and joined his old freedom fighter friends from back when he fought along with Charles or Uncle Chuck as Sonic called him.
Razor finally found out where the last Chaos Emerald was and tried to get it. Unfortunately Knuckles kept it well guarded and virtually impossible to get to. Razor had almost ran out of ideas when he thought about Chaos Control, but he had left the other emeralds with Aleena. That didn't stop him, he tried over and over a year later when Sonic and his friends finally defeated Robotnik and freed Mobotropolis Razor perfected it. "I've got it!!!" he said. "I've mastered Chaos Control!" Finally he used it to teleport inside and steal the emerald without Knuckles noticing. The emerald had healed and Razor took it out of the jar and ran it to Aleena. When Mobius was free Sonic found a way to temporarily restore Uncle Chuck's freewill who, with the help of an incredibly intelligent young fox named Miles Prower, or Tails because he has two tails, successfully created a functional and safe De-Roboticizer.
Mobius was free and Robotnik was left for dead in the ruble of his doomsday base. The Floating Island was renamed Angel Island. Sonic left his home and toured the world looking for excitement. Manic became a drummer. Sonia accepted the role of next in-line for the throne. Knuckles continues to guard the Master Emerald on Angel Island. Razor stayed with Aleena and Sonia at home.
