|This article is about a/an giant monster in Choudenshi Bioman.|
An jellyfish-themed Mecha Gigan with two bodies: a main physical body and a floating head that can emit electrical energy for attack.
Jellyfish Canth is a Mecha-Gigan set up as part of a major scheme by Gear to set off multiple "black hole bombs" simultaneously using its electrical ability in order to suck Tokyo into a massive, combined black hole and make it vanish. Due to Nanbara investigating the brother of a boy who inadvertently discovered the actions of Gear, he leads Bioman into facing the Mecha-Gigan before it can set off all the bombs. After a tough battle, Bioman defeat the giant body with Super Maser's Dashing Beam, then with the main head with Straight Flash.
