During the "Monsters Unleashed" storyline, Fin Fang Foom, Gorgilla, the Green Thing, and Zzutak confront Kei Kawade in the forest outside his house and warned Kei Kawade against the preceding monster summoning. He was later seen falling from the sky alongside the other monsters, because they had been summoned by Kei Kawade to help superheroes fight the Leviathons. He was told by Tim Boo Ba that he and the other monsters are not fighting of their own volition. Kei Kawade later sends Fin Fang Foom to assist the Heroes for Hire against the Leviathons in Hell's Kitchen. When the Leviathon Mother shows up and calls out to Kei Kawade, Fin Fang Foom shows up to challenge her. When Kei Kawade confronts the Leviathon Mother and gets her attention, she spits out Fin Fang Foom. Following the Leviathon Mother's death, Fin Fang Foom and the other Goliathons confront Kei Kawade. Even though Kei Kawade thanks the Goliathons for their help in fending off the Leviathons, Fin Fang Foom warns him about summoning them again before the Goliathons are teleported away.
