Karehaan kicks off the Dark Fall's invasion of Earth, tasked with capturing Flappy and Choppy to force them into revealing the Fountain of Sun's location. When the duo refuses to cooperate, he escalates to torture—which finally prompts Saki and Mai to transform for the first time.
Plant-themed through and through, Karehaan can turn wood-based objects into Uzainaa monsters and has a distinctly vegetation-like appearance himself. His name derives from "kareha," the Japanese term for dead leaves, which is fitting given that his true form is literally just a dead leaf.
