Mea is called as "Mea the Red Hair" by Tacolas.

But he forsakes the plan because Mea accompanies with Yami, and switches to destroy the Earth with his spacecraft in order to kill Mea.

He tries to flee Mea and Yami with the Space Plant, but Momo aids Yami to defeat Tacolas together. He is pummeled by Yami and transferred to the Galactic Police.
