Monster Party - Story

Story

The story centers on a child named Mark who is accosted on his way home from a baseball game by a winged, gargoyle-like alien named Bert who requests his assistance in ridding "evil monsters" from his realm, "Dark World". Mark is reluctant to help, but Bert insists, saying that Mark can use his "weapon" (his baseball bat) to fight enemies. He quickly whisks him away, and on the way to Dark World magically fuses himself to Mark so that they are one being (with Mark able to transform into Bert for a limited time).

This bizarre plot introduction sets up a game that is filled with variations on many traditional horror characters and themes (sometimes with ironic twists), as well as relatively novel characters all its own. Some traditional horror bosses the game features include a mummy, giant spiders, zombies, Medusa, a Dragon, and The Grim Reaper. The game also features several enemies drawn from Japanese folklore and Japanese urban legends, such as Banchō Sarayashiki's well and Jinmenken (human faced dogs). Enemies unique to the game include a large, talking caterpillar; walking pants; a giant cat that hurls kittens as projectiles; and a bouncing piece of fried shrimp.

After making his way through Dark World and ascending into what appears to be some kind of Heavenly realm, Mark fights and defeats the Dark World Master. His realm now free of monsters, Bert returns Mark home and leaves him with a parting gift for his help. When Mark opens the box, a beautiful princess emerges; after a few seconds, though, she transforms into a hideous monster who melts Mark's flesh from his bones.

Mark suddenly awakens in his bed, his body intact. Believing his adventures in the Dark World to have been a bad dream he prepares to leave the house only to find Bert looming before the front door. Bert asks Mark if he is ready to go again, and the game ends.
