The Chaos Rings (カオスリング Kaosu Ringu?) are a set of six multicolored Rings that appear in Knuckles' Chaotix. They are considered mere prizes won in the Special Stages in the English manual, but they are actually a considerate part of the storyline in the Japanese manual. Regardless, only by collecting all six will the player be rewarded with the game's good ending.
In Knuckles' Chaotix, the Chaos Rings are collected in much the same way the Chaos Emeralds are in the original Sonic the Hedgehog. If the player successfully completes a Special Stage, which can be accessed through a Giant Ring at the end of an Act, the player will awarded with a Chaos Ring.
Collecting all six Chaos Rings is the only way to thwart Dr. Eggman's ambitions and attain the "good ending", with cameo appearances from Sonic and Tails. If the player completes the game with fewer than six Chaos Rings however, then any Chaos Rings they have collected will be shattered by the power of Dr. Eggman's giant Dark Ring. The "bad ending" will then play over the credits, with the final boss of Knuckles' Chaotix menacing a burning city.
The Chaos Ring storyline goes completely unmentioned in the United States manual for Knuckles' Chaotix, which features a drastically different plot, revolving around Dr. Robotnik trying to steal the "Power Emerald" from "Carnival Island". The Chaos Rings can still be collected, but are never explained.
- During the Knuckles' Chaotix comic special from Archie Comics, the Chaos Rings were replaced with Power Gems.
- Chaos Rings were originally known as "Holy Rings" during development.
