Suicune 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 Raikou. Later, Yellow freed them and the three started roaming the land in search of worthy trainers to battle along with. Suicune challenged the most number of trainers, and eventually partnered with Misty to fight Lugia and Ho-oh at the Pokémon League. It then assisted Crystal in chasing Mask of Ice into the voids of time. It disappeared into the lands afterwards.
