Grotes Canth

Grotescanth (グロテスカンス): A self-assembling Mecha Gigan created by Prince, incorporating Mason's Power Coils into its design while taking the general's scheme as his own. Eventually, Prince summons Grotescanth from underground and pilots the Mecha Gigan to overpower Bio Robo before it loses its Power Coils before forced to return them when Prince goes on a killing spree. When Prince pilots Grotescanth in a later battle, the Mecha Gigan is destroyed when Bio Robo targets the command module.
