Rider Gauges

A Rider Gauge is an energy meter on the chest armor plating of a Kamen Rider. Its purpose and function is to act as a way for the user of a Gamer Driver to see how much damage they have taken. If the Gauge energy reaches its lowest point, an alarm klaxon will sound and the Gauge will flash. The Rider in question who is in this predicament must do one of three things:
 * 1) Abort their operation by deactivating the Gamer Driver and retreat to tend to their injuries or to form a new strategy for fighting the enemy.
 * 2) Find a Recover Energy Item to heal or a defense-type energy item to enhance them to evade or negate oncoming attacks.
 * 3) Continue fighting while dodging attacks and avoid getting hit to defeat the Bugster.

If the Rider takes too much heavy damage, the gauge will drop to zero and the Rider will die or as Asuna put it, the Driver powering the suit would go into "Game Over".
