Monsteroso

History

Origin

Monsteroso is a microscopic being who’s entire world was small enough to fit on a single slide of a microscope in the laboratory of an unnamed professor. Monsteroso was hatched from an egg and continued to grow within his microscopic land until it began to flood with water around him. Unknown to Monstero an assistant by the name of Smith had taken the slide and placed it in the sink to wash unintentionally damning Monsteroso and his entire world.

Monsters Unleashed

Monsteroso was later seen during the invasion of the monstrous leviathans who were falling to Earth from outer space. How Monsteroso survived his watery death is unknown but he along with other Marvel Monsters appeared to combat these new threats that were dead set on destroying life on Earth.
