Oonyuudou

Oonyuudou appeared in 1994 movie called Ninja Sentai Kakuranger: the Movie. Oonyuudou (オオニュウドウ Ōnyūdō) is a giant elephant/kappa Yokai who is the loser son of the Yokai Bank's owner.

Annoyed with being seen as a loser, Oonyuudou uses his wand to shrink objects and create his "dream town" to rule over. He uses his tuba to place people under his illusions until the Kakurangers' "Lightning Wave" negated this effect. He tries to shrink Muteki Shogun, but it ends up being returned to normal size when he is killed by the Shogun's sword, with everything he shrunk returning to normal.

Though unseen, Oonyuudou's spirit presumably emerged within the Seal Door along with all the other defeated Yokai, after their master Daimaou was finally contained there by the Kakurangers. Reeling that they were now powerless in captivity, the Yokai all vowed that they would one day be reborn and regain their power, cursing humanity.
