|Season:||Uchuu Keiji Shaider|
Meromero (メロメロ Meromero?): A purple skull-faced Fushigi Beast with a ram-headed staff, Meromero disguised herself as a witch to lure children with delusions of magic they can be switched with the Beasts posing as them in animal form so that the real children can be turned into loyal animal-human hybrids to manipulate their parents into submission. When Dai gets involved, he manages to find the lab at an amusement park with the aid of Yohko's dog. With Annie providing cover, Shaider manages to restore the mutated children and destroy the lab. As Annie takes the captive children and Yohko to safety, Shaider pursue Meromero into the Fushigi Dimension where she gained the ability to disappear and attack him out of nowhere. But Shaider uses his Shaider Scope to counter before destroying with Shaider Blue Flash. Its powers include a witch and butterfly disguise, a staff with teleportation properties and can emit explosions, retracting into her levitation cloak, invisibility, and telekinesis.
