 The Mad Thinker used Gargantua as a field agent, hoping that he would be publicly defeated by Wasp and Wonder Man (who were engaged at the time in high-profile protests against the government's first proposed legislation regarding superhero registration/regulation).As planned, they defeated Gargantua, and Mad Thinker helped sway the public opinion against the legislation.While in the Vault, Gargantua joined the Wizard and the Force of Nature in a riot against the Guardsmen, who would not allow Terraformer access to plant life.
