The first Bakegani sighted attacked people near its saltwater territory at Boso with Hibiki having a hard time fighting a Makamou due as String-instrument Oni are better suited. But Hibiki managed to destroy the Bakegani with his Kaen Renda form. A "freshwater" Bakegani was fought at Nikko in episode 15, lacking barnacles as it grew up on the river. It attempted to kill a weakened Zanki, but ended up being destroyed by Zanki's Raiden Gekishin. A river-type appeared at Kazuno in episode 26, destroyed by Todoroki's Raiden Gekishin.
