The Chaos Rings
The Chaos Rings are a group of six powerful multi-colored rings that appear in Knuckles' Chaotix. They were accidentally created when Dr. Robotnik came in contact with the Special Ring, a Super Ring-like artifact once used by Knuckles' people. They can be collected by accessing Special Stages, and only by collecting all six will the player be rewarded with the game's good ending.
Dr. Robotnik discovered the Special Ring once a mysterious island appeared out of the ocean, and witnessed a phenomenon in which it interacted with the Floating Island's Pillar to create six similar rings. He converted the island to his Newtrogic High Zone base to continue his research and synthesize Dark Rings. Dark Rings appear in badniks and during Robotnik's boss battles, but upon defeat the Dark Ring falls out and disintegrates. After Metal Sonic loses to the player character and his partner, he appears before Robotnik and the two leave off-screen with the Special Ring; the game is unclear whether or not they merely escaped or if Metal Sonic transformed into Metal Sonic Kai (the final boss) with its power.
- Chaos Rings do not trigger a Super transformation once collected.
- During the Knuckles' Chaotix special from Archie Comics, the Chaos Rings were replaced with Power Gems.
- Chaos Rings were originally known as Holy Rings during development.
- The Chaos Rings are similar to the Seven World Rings minus a white Chaos Ring.
