At one such restaurant he attempts to hypnotize Shigeru Jo and force him to kill Yuriko Misaki. He can swing his giant metallic tail and severe limbs or chomp through walls with his iron jaw as well as swim. He was destroyed by Stronger's Stronger Electro Kick.
Waniida's husk was later discovered by Shigeru and Yuriko as part of a Kikkaijin graveyard in a Black Satan base.
