Powers/Abilities: Monstrom had superhuman size, strength (class 100?), and durability.

History: (Tales To Astonish I#11) - Monstrom was an alien explorer whose vessel crashed on earth 1,000 years ago. Unable to make repairs, he hid beneath the Bayous, hoping that one day humans would become advanced enough to assist him in repairing the vessel.

At one time in recent years, he emerged from the swamp, but was immediately set upon by the local humans, who feared him. Finding that he was afraid of fire, they drove him back into the Bayous with torches, and he returned to his spaceship to wait.


(Monsters Unleashed II#2) - The Inhuman Kid Kaiju summoned Monstrom along with numerous other monsters to an area outside San Diego, California in defense against the Leviathons.

(Monsters Unleashed II#3) - Monstrom joined the fight against the Leviathons. Earth's heroes watched the monsters summoned by Kid Kaiju defeat the Leviathons. After the battle Monstrom and the other monsters were teleported back from where they came.

(Monsters Unleashed II#4) - Monstrom aided S.H.I.E.L.D. fighting a Leviathon in Shanghai, China. Kid Kaiju later teleported Monstrom to New Orleans, Louisiana where Monstrom aided Old Man Logan against a Leviathon.
