# List of monsters in Marvel Comics

This article lists monsters in Marvel Comics.

## History

In the earlier parts of Marvel Comics, issues such as Journey into Mystery, Strange Tales, Tales of Suspense, and Tales to Astonish would detail stories of its different monsters. They consist of various monsters from mythologies (e.g., giants, e.g., cyclopes, trolls, ogres, etc., orcs, goblins, imps, undead, e.g., zombies, mummies, and vampires, etc., demons, ghouls, werewolves, werehyenas, werecats, and wererats, etc.), and novels (e.g., Frankenstein's monster and Count Dracula, etc.), giant aliens, kaiju, Deviant Mutates (and even human and animal mutates/mutants), and experiments that went horribly wrong. In later Marvel Comics stories, some of the monsters would later be seen inhabiting Monster Isle.
During the "Monsters Unleashed" storyline, the Inhuman Kei Kawade summons various monsters, identified as Goliathons, to help the superheroes fight the Leviathon Tide.
