Simon the Monster Hunter

Simon the Monster Hunter is arguably the main antagonist of the Aaahh!!! Real Monsters cartoon series, rivalled only by the Gromble in terms of his frequent antagonism towards the group: however unlike the bullying Gromble Simon is driven by obsession and a geniune desire to capture the monsters so as to prove to the world that monsters are real.

Simon is one of only a very small number of human adults who knows of the existence of monsters and is considered completely insane by both human and monster alike - which he most likely is, considering the extreme lengths he goes to in his fanatical crusade.
