Regigigas was awakened and captured by Palmer with the help of Brandon’s Regirock, Regice and Registeel. However, since he could not put it to good use, he released it back to the Snowpoint Temple, where it slumbered and later secretly entered a Pokeball of Platinum’s on its own will. It showed itself during the Spear Pillar incident and helped to fight Dialga and Palkia after choosing Dia as its trainer. After the battle, it refused to come out until Charon attacked the boys with Heatran. It assisted in the battle among the legendary Pokemon in the Distortion World.
