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

A King's Rock first appeared in Ring Masters, where Ash received it as a prize for winning the Sumo Conference. Misty's Poliwhirl later used it to evolve itself into a Politoed in Outrageous Fortunes.

Another King's Rock appeared in A Crowning Achievement, where it was found on a rock after the water level in the local river dropped dramatically; Alice's Slowpoke used it to evolve into a Slowking.

A Deep Sea Scale and Deep Sea Tooth appeared in The Evolutionary War, where the people in the A-B-C Islands were having an argument over which Pokémon was best, Gorebyss or Huntail.

A King's Rock, two Deep Sea Teeth, and two Deep Sea Scales appeared in Showdown At Linoone as some of the items Tokin picked up.

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.

In Fighting Fear with Fear!, Ash received a Razor Fang from Gary. Later in the episode, he used it to evolve his Gligar into a Gliscor.

History

Gold, Silver & Crystal arc

In Quilava Quandary, Gold was given a King's Rock by the Day-Care Couple after training with them, which he gave to his Poliwag to hold. In Ampharos Amore, Gold's newly evolved Poliwhirl and Silver's Seadra evolved into a Politoed and a Kingdra, respectively, while holding their respective evolutionary items, King's Rock and Dragon Scale.

Diamond & Pearl arc

In Yikes, Yanmega! II, Diamond's Lickilicky, Kit, used a Protector to protect itself from Mars's Yanmega swarm's soundwaves. Roseanne later revealed that the Protector was one of the items she used in her research of Pokémon Evolution, the other seen items being a Reaper Cloth, Dragon Scale, Magmarizer, and King's Rock.

HeartGold & SoulSilver arc

In Dealing With A Koffing Fit, Silver's Sneasel evolved into a Weavile due to having gained experience while holding a Razor Claw, which had been given to Silver by Green.

In Raising the Stakes with Rhyperior, it was revealed that Silver had given Blue a Protector to be held by his Rhydon, allowing it to evolve into a Rhyperior when it was traded between the two Trainers. Afterwards, Blue had let Silver keep Rhyperior as a replacement for his lost Ursaring.

Trivia

• In Pokémon Black and White, the Prism Scale was incorrectly categorized in the Bag as a general item and not as an evolution-inducing held item. This was later fixed in Black 2 and White 2, but starting from Pokémon X and Y it is now again incorrectly categorized, this time as a valuable item.
• Along with being listed amongst the evolutionary stones, the Oval Stone has the "Use" option when selected in the Bag, but if the player tries to use it, it won't say "Able" under any Pokémon.
  • This makes it the only evolutionary item with "Stone" in its English name which is not an evolutionary stone.
