An evolution-inducing held item is an item which makes the Pokémon holding it evolve when a certain event happens, such as if the Pokémon is traded or leveled up. The item disappears once the Pokémon has evolved. For evolution-inducing items that are not meant to be held, see the page on evolutionary stones.

In the anime

Many evolution items have appeared in the anime. The first one to appear was the King's Rock which appeared in Ring Masters where Ash won it in the Sumo Conference and Misty's Poliwhirl used it to evolve itself into a Politoed in Outrageous Fortunes. A DeepSeaScale and DeepSeaTooth appeared in The Evolutionary War where the people in the A-B-C Islands where having a argument over which Pokémon was best, Gorebyss or Huntail. In One Big Happiny Family!, Brock carved and made an Oval Stone for his newly born Happiny, which later helped her evolve into a Chansey in The Brockster is In. The most recent appearance is in Fighting Fear with Fear!, Ash got a Razor Fang from Gary Oak and he used it to evolve his Gligar into a Gliscor.
