The Warhogs, under the leadership of Warhog, were a civilization of people who lived underneath Gotham.
The group used poisonous chemicals, manufacturing them in a well-equipped lab they had back at their base.
The Warhogs were longtime enemies of Doctor Phosphorous' group of underground settlers. He attempted to alleviate the tension by bequeathing his daughter Tinderbox to Warhog's son Rake, but the deal went sour, causing a war between them. In a fight between Phosphorous and Warhog, the latter was killed by the cave collapsing. The rest of his settlers were then trapped inside a radiation bunker that wouldn't reopen, thereby dooming the rest.
