An energy gauge.
Hero Gauge is a game mechanic that appears in  . It is an energy gauge used for the Shadow the Hedgehog Hero Shadow state.
The Dark Gauge is a gray-framed gauge that appears in the upper left corner on the
HUD. Inside it is a blue energy bar and on the left end is a hook.
In gameplay, the Hero Gauge is filled by committing heroic deeds.
Once the Hero Gauge is filled, the player transforms into
Hero Shadow, which grants infinite ammo for weapons, invulnerability and usage of Chaos Control. However, the Hero Gauge will steadily decrease while Hero Shadow is active and using Chaos Control will deplete it completely. Once the Hero Gauge runs out Shadow reverts back to normal.
Due to the nature of certain missions of some stages, destroying
Eggman's factions will only occasionally provide energy for the Hero Gauge.
