Sonic Fighting Heroes: King of The Ring

Dr. Eggman invades the G.U.N Agency Headquarters, in search of any uncovered information surrounding his grandfather, Dr. Gerald Robotnik. In the process of this invasion, he successfully locates The Space Colony ARK’s case files, in which he finds written documents by Gerald, stating that he’d discovered a method to siphon chaos energy, & use it on himself, & hopefully Maria. It stated that the Chaos Emeralds could heal the user if use correctly, a method of which he planned to use as a cure for Maria’s sickness.

There is also a section in the document which states that he had found out how to use chaos energy in the same way Shadow & the “Ancient Hedgehog Hero” from the paintings in Hidden Palace could. Bestowing himself with a great power unlike anything he’d ever seen. It was part of what allowed him to create such powerful beings with such little time as he had been using the emeralds to grant himself enhanced speed & strength.

With this newfound discovery, Dr. Eggman vows to find a way to use the emeralds in the same way his father did, and exact revenge on Sonic & Friends on equal terms. In order to distract Sonic & Friends from catching onto his plan, he creates a tournament with the Master Emerald as the grand prize, something which was easily stolen from Knuckles. After word of the tournament is spread through an interrupted TV broadcast, Sonic & Friends all enter the tournament in hopes of ensuring that the heroes will take the Emerald back to Angel Island in the end.
