The City Volcano is a resort inside a volcano within New York City.
In June of 2020, a duel between Sebiscuits Cardarphen and Baby Intelligence would also take place in the volcano. Cardarphen suffered grievous injuries, including the loss of his limbs, and the searing of his lungs, when he attempted to jump to higher ground from a piece of stone on the lava river, only to be immobilized by Baby Intelligence. He was later rescued by the latter, who brought him back to the MBH, where he was rebuilt into the popular cyborg of the S.M.S.B. at the MBH Medical Center.
