A video game item (or spell) which activates automatically upon your death to revive your character from KO, giving you a second chance. It may heal you partially or fully, but either way it is invariably depleted, lost, or destroyed in the process of reviving you. Expect Artificial Stupidity to really hit your partners if Auto Revives work on them as well, as they'll easily burn through your whole supply when it only really matters if you die or not. Subtrope of Death-Activated Superpower. Compare One Up.
