Plot
An evil being named Dremagen (the master of a thousand dimensions) begins to collect heroes from across different worlds and rule them all. She does so with a clone army she made of the heroes.

In the dimension that Dremagen forced several heroes into, Amy Rose meets Ax Battler and requests his assistance to help their friends. They soon run into a clone of Joe Musashi and manage to defeat him. Afterwards, the duo meet up with AiAi and continue their quest with him. Along the way, they run into villains that are helping Dremagen's cause, such as Mr. X, Death Adder and Dr. Eggman.

Trivia

 * When Amy meets Joe Musashi for the first time, she does not think highly of him as she has a friend who is a ninja as well, referring to Espio the Chameleon.
 * Ax calling Amy a rabbit (despite her appearance) may be a tongue in cheek reference to Sonic the Hedgehog's original design, where he was formerly a rabbit.
