A Revive is a type of item from the Pokémon games. They can be used during or out of battle to restore a Pokémon which has fainted. They can be found on the ground, whether readily visible or hidden from sight and requiring an Itemfinder to locate. Standard Revives can be bought at some Poké Marts. In Generation IV, Revives and Max Revives can be found while digging in the Underground.
A standard Revive is an octahedron. A Max Revive is normally portrayed as a 24-faced polyhedron, but in the Sinnoh Underground it appears as a 32-faced polyhedron.
