World Boss Loki

The Demon Realm is the fourth world in Mushroom Kingdom Fusion. This world features horror-themed levels, primarily based on the DOOM, Castlevania, and Ghosts 'n Goblins series, as well as other dark-themed games. The World Boss is Loki.

Description[]

The Demon World is the home of countless monsters and demons of all kinds, but unlike Gehenna, there are also some peaceful demons and living humans, like the heroic Sir Arthur, who protects his kingdom from the forces of evil. This world underwent a fusion effect with many other dark realms, thanks to the Fusion portals. The two demon lords, Astaroth and Loki, are using this opportunity to build a greater hell army, and a member of the Fusionist's Finest, named the Necromancer, came to this world to find a monster called the Behemoth to bring him back to life and control it. Arthur teamed up with the Mushroom Kingdom Coalition to stop their evil plan to take over the realms.

To access this world, the player is required to complete Banshee Boardwalk to unlock the World 4 secret exit.
