Gargantuan (Totally Spies)

Gargantuan is a tech-armored behemoth featured in the Totally Spiesepisode "Escape From WOOHP Island".

History
Little is known about Gargantuan except that it was taken in by W.O.O.H.P. for trying to destroy the entire planet, only to have escaped thrice causing mondo damage before being caught again and left on an island. Sam, Clover and Alex think that it was a robot at first. While they were looking for Britney on the island, the girls encountered with the giant as it grabbed Alex in the air.

Clover attempted to locate Gargantuan's motherboard, only to find out that its insides are all organic (in other words, Gargantuan wasn't really a robot). Sam and Clover then tied up Gargantuan by its legs, which made it fall directly to the ground. It was not seen again for the remainder of the episode. It is more than likely that Gargantuan was destroyed along with the entire island once it blew up.
