Shark Canth

Samecanth (サメカンス): A Shark-based Mecha Gigan with a built-in molecular amplifier in its eyes that gives Monster, Messerjū, and their Mecha Clones enhanced super strength that makes them invincible against the Bioman before going on a city-wide rampage. However, the effects were temporary and result with Samecanth being deployed by Doctor Man to recharge his forces before Jun destroys the Mecha Gigan's eyes. After Zyuoh saves Monster upon Meezerju's defeat, Samecanth is destroyed in battle by Bio Robo.
