Kerokero (ケロケロ Kerokero?): A green reptilian Fushigi Beast with a mantis-like torso for a head to help Hessler capture a rebelling teenage girl named Yukari, who is actually the princess of Planet Freyn and sent to Earth during Fuuma's genocide to be safe until she is of proper age to return to her homeworld with the other survivors and rebuilt it. When Dai and Annie uncover the truth, Yukari refused to believe it and was captured by the Fuuma as she runs off when brought to where the earth-bound Freynians are to gather. After saving Yukari, Shaider battles Hesseler's group and Fuuma aircraft before chasing Kerokero into the Fushigi Dimension. After chopping its head off, Shaider destroys Kerokero with the Blue Shaider Flash. Soon after, Yukari finally leaves for Freyn. Its powers include a ringed staff, a human disguise, high jumping, invisibility, telepathic explosions and can survive decapitation.
