Raikou was resurrected from Ho-oh’s powers 150 years ago after it perished in a fire at the Burnt Tower. It became Ho-oh’s follower since then, and while trying to protect its master, it was once sealed into the ice mirrors of Mask of Ice along with Entei and Suicune. Later, Yellow freed them and the three started roaming the land in search of worthy trainers to battle along with. Raikou partnered with Lt. Surge, and fought Lugia and Ho-oh at the Pokémon League. It then assisted Gold in chasing Mask of Ice into the voids of time. Sometime prior to the opening of the Hoenn Battle Frontier, it was captured by Anabel and became her team’s major powerhouse.
