The Monterrangutan is a beast of unknown origin. It was discovered following the Monterrey earthquake caused by Doctor Apocalypse.
The beast is a 25’ tall simian creature. It was discovered by the Valkyrie in a previously undiscovered subterranean chamber underneath Monterrey. When found, the Monterrangutan was in the fetal position encased in a layer of calcified stone.
While archaeologists were excavating the creature believing it to be a mummified artifact, the Monterrangutan burst free of the encasing stone and went on a rampage.
The heroes of the Eclipse battled the creature, unfotunately causing the beasts death during the fight.
The corpse has been taken to the Pacifico Zoo for examination.
