Synopsis

A Chaos Control triggered by Sonic transports several characters from his universe (Tails, Amy, Knuckles, Cream, Rouge, Shadow...) to an alternate version of Earth. There, they meet Chris Thorndyke, a human teenager who offers them refuge. Together, they confront Dr. Eggman, determined to dominate this new world, while searching for the Chaos Emeralds in hopes of returning home.

Across its 78 episodes, the series adapts several video game arcs while introducing original stories, notably the famous galactic Metarex arc. The series skillfully blends fast-paced action sequences, humorous moments, and deeper emotional passages, especially around Chris's character and the dilemma of friendship between different worlds.
