Mantis Kikkaijin (カマキリ奇械人 Kamakiri Kikkaijin?, 9, 17, 26): A mantis monster. He possesses the conductor of a travelling band troupe, using his nature as a praying mantis to interfere with the music's frequency with a chirp. This creates a cacophonic sound that either causes death or makes adults attain a desire to kill children. He then possesses a church cleric onwards to trap Tobei and Yuriko. He can turn both his normal hands into a scythe and ball-chain mace respectively. The scythe in his arm can be thrown as a boomerang. Destroyed by a combination of Stronger's Stronger Electro Kick and Stronger's Electro Water Fall.
