In the anime

A Thunder Stone in the anime

The Thunder Stone made its anime debut in Electric Shock Showdown, when Nurse Joy gave Ash a Thunder Stone so that he could evolve his Pikachu in order to defeat Lt. Surge's Raichu. Pikachu, however, refused the offer. Ash kept the Thunder Stone in case Pikachu ever wanted to evolve; however, in Pika and Goliath!, a similar scenario occurred and Pikachu still refused to evolve. Seeing his determination to not evolve, Team Rocket stole the stone, planning to sell it.

In The Battling Eevee Brothers, the Thunder Stone appeared as part of a collection held by the Eevee brothers. Two of the Eevee brothers offered a Fire Stone and Thunder Stone to Brock and Ash to evolve their respective Vulpix and Pikachu, though both refused.

Ash had to find a Thunder Stone in a scavenger hunt as part of the Wishing Bell Festival contest in Climbing the Tower of Success!. He came across a young man in possession of one who tried to toss it to him from a long distance. The Thunder Stone nearly came in contact with Pikachu but he jumped out of the way just in time, leaving Ash to catch it.

Mystery on a Deserted Island! featured the Thunder Stone along with all of the other Evolution stones available as of Generation V.

A Thunder Stone appeared in To Catch a Pokémon Smuggler! as a part of Clemont's explanation of how Pokémon Evolution works, Pikachu's evolution into Raichu working as an example of stone-induced Evolution.

A full set of Evolution stones was seen on display in a stone shop in Geosenge Town in The Cave of Trials!.

In the manga

In The Electric Tale of Pikachu manga

Evolution stones in The Electric Tale of Pikachu

The focus of the chapter To Evolve or Not to Evolve, That Is the Question! was Evolution stones, including the Thunder Stone.

In the Pokémon Adventures manga

A Thunder Stone in Pokémon Adventures

In The Kindest Tentacruel, the Pokémon Fan Club Chairman told Yellow about a legend of an underwater dome at the bottom of Vermilion Harbor, housing a set of Evolution stones which, unlike normal stones, did not disappear after making a Pokémon evolve, allowing them to be used repeatedly. The cause of Red's Poliwhirl's evolution had been one of these said stones, proving the legend to be true. Yellow was later led to the dome by a wild Tentacruel, finding a Leaf Stone in it, but the Fire, Thunder, and Water Stones were missing. Later, it was revealed that Giovanni had given them to Red so he could freely evolve and devolve his Eevee.

In the Pokémon Zensho manga

A Thunder Stone in Pokémon Zensho

In Indigo Plateau, Satoshi's Pikachu used a Thunder Stone to evolve itself into a Raichu before Satoshi left to challenge the Elite Four.


  • Through a glitch in the Generation I games, Pokémon that would normally require an Evolution stone to evolve can be evolved without it, provided that the Pokémon levels up in the battle and the player has sent out a specific Pokémon in the same battle. In the case of the Thunderstone, this Pokémon is Growlithe.
