The Thunder Stone is an evolutionary item in the "Pokemon" games. Players use it to evolve Pikachu into Raichu and Eevee into Jolteon. If evolved at an early level, the Pokemon will be unable to acquire the level-up attacks of their unevolved forms, so it is wise to wait until the Pokemon have learned the desired attacks before you use the stone. Upon evolving into Raichu and Jolteon, Pikachu and Eevee will benefit from increased stats, most notably in Special Attack and Speed.
