Pokemon Sword & Shield: Every Pokemon That Evolves With The Thunder Stone (& Where To Catch Them)

"Thunder Stones have been a part of the Pokemon world since the first generation of games. At that time, it could only evolve two Pokemon. Eight generations later, a Thunder Stone can evolve as many as five Pokemon. Five is very little in comparison to the over 800 Pokemon that now exist in the Pokedex since Sword and Shield came out. True to the stone's name though, it is only usable on Pokemon that can evolve into Electric-types." - click image for article
