Kagayaku is Winx's Haos Omega Leonidas.
Omega Leonidas, being Leonidas in its evolved state, now has two large horns protruding from its muzzle, one smaller than the other, while two horns just off its eyebrows, giving it an appearance similar to Neo Dragonoid. Spikes run along his back and tail. Large claws on its three-fingered hands and two-toed feet make even Leonidas's body a valuable weapon. Kagayaku is a very strong Bakugan. When it comes to battle, he uses quick but powerful blows to defeat his opponents.
Kagayaku is a very humble Bakugan. He likes to brawl but hate to lose. He is also a ladies man. He often hits on Suraizero even though he knows that she's married.
At first, Surai and Kagayaku were dating. But then, he cheated on her. He still loves her but Surai could care less for him.
Kagayaku and Blackout were really good friends.
Kagayaku and Gaia were allies until Kagayaku found out Gaia was using him until he didn't need him anymore.
