Hyper Mode

Hyper Mode is a special mode that all fighters can activate in any fight in Sonic the Fighters to increase the speed of their moves and unlock access to special Hyper Moves in the game. However, the fighters lose some of their shields in the process of doing so. For the final fight against Eggman, the characters toss the Chaos Emeralds into the air right before fighting him. They then activate it in order to beat Eggman in less the fifteen seconds, so that they may escape the destruction of the Death Egg 2. Due to this event, Hyper Mode might be a weaker type of Super mode; a similar thing happens in Mario & Sonic at the Olympic Winter Games during the Sonic figure-skating contest but looks slightly different and is used to take down a smaller, frozen Perfect Chaos.

Trivia

 * This is the only enhancement mode that Amy has ever been shown to take in the games.
