Cosmic Reset Button

The Cosmic Reset Button is a mechanism that was incorporated into the Death Egg Mark 2. As its name suggests, its purpose is to reset reality in order to suit the plans of Dr. Eggman, which it does by launching the Genesis Wave.

History
Dr. Eggman first used the Cosmic Reset Button to alter reality on Mobius, creating a far simpler version of the planet. However, Super Sonic was able to undo the effects of this initial Genesis Wave, and the button was rendered inoperable for a time due to the loss of the Chaos Emerald that provided its power source. However, it was later used by Eggman and his new partner, Dr. Wily-who had located the missing Chaos Emerald in his own dimension-to alter both of their realities as part of their alliance against both Sonic and Mega Man.

Background Information

 * The term reset button typically refers to a mechanism on a video game system that allows the player(s) to restart the game. Ironically, the Cosmic Reset Button essentially restarted the conflict between Eggman and the Freedom Fighters in its first use. It also had the effect of making Mobius much closer in nature to the simplicity of the early Sonic the Hedgehog video games as opposed to the more complex comic storyline.
