Korrigan, it appears, was once a Meloetta, but she turned over to the dark side because human beings turned her arts and inspiration into tools of manipulation and war and greed. Which is when...she started to embrace arts not to inspire, but to seduce and manipulate and cause human beings to attack and kill each. She was so dangerous that Meloetta had to defeat her, which happened, but then...Team ISIS broke into the ruin site where Korrigan had her lair within the Ingland Region and stole a hair of hers from the Cursed Well and cloned her, with the intention of using her powers in an attempt to destroy their enemies.
