Regi (Pokémon)

Regirock (レジロック, Rejirokku), Regice (レジアイス, Rejiaisu), Registeel (レジスチル, Rejisuchiru), Regigigas (レジギガス, Rejigigasu), Regieleki (レジエレキ, Rejiereki), and Regidrago (レジドラゴ, Rejidorago), alternatively referred to as the Regis, the Legendary Giants, and the Legendary Titans, are Pokémon species in Nintendo and Game Freak's Pokémon franchise. Regirock, Regice, and Registeel were first introduced in the 2002 video games Pokémon Ruby and Sapphire, Regigigas was first introduced in the 2006 games Pokémon Diamond and Pearl, and Regieleki and Regidrago were first introduced in the 2020 Pokémon Sword and Shield downloadable content expansion pack The Crown Tundra. In Pokémon lore, Regigigas towed continents into place and created the five inorganic Regis. All Regis are sealed away, left to be discovered by players.

During development of Pokémon Ruby and Sapphire, designer Ken Sugimori and his team decided to create more complex humanoid designs, in contrast with the more "babyish" designs of the prior games. The Regis have been met with a mixed response from critics, having been criticized for their inorganic appearance. Regigigas has received commentary for its in-battle weakness due to its ability Slow Start. The Regis have been the subject of urban legends and various Internet memes.
