Regirock

Regirock in the anime

Regirock debuted alongside its fellow guardians in Lucario and the Mystery of Mew as a protector of the Tree of Beginning, initially attacking Ash and his friends as perceived intruders before recognizing they were not a threat. It made its animated series debut in Battling the Enemy Within! under the ownership of Brandon, who used it to defeat Sceptile while Ash was possessed by the King of Pokelantis, and it reappeared in Pace, The Final Frontier! before being brought to Sinnoh in A Pyramiding Rage! and Pillars of Friendship!. Regirock is the first Legendary Pokémon shown as a caught Pokémon in the animated series. Separately, Danika and Quillon confronted a Regirock in Looking Out for Number Two!, and Chasing to the Finish! revealed they had caught it.
