LORD FUSE

Fuse is the leader of Planet Fusion and is the main antagonist in the game. He is one of the strongest monsters in the game, surpassed only by the Don Doom, Bad Max, Fusion Kimchi, and the turrets inside Vilgax's ship, all of which posess incredible defensive power for respective reasons as Bad Max and Don Doom are gigantic and take attacks because of their size, Fusion Kimchi because he is basically a walk-through cloud, and Vilgax's turrets for their armor. He is the one responsible for the destruction befalling the world and for creating the Fusions, the evil twins of the Cartoon Network heroes. Fuse has an "avatar" that can be defeated, we will learn that Fuse and his home planet are one and the same. Over the millenia, Fuse has mastered many different forms of science, magic and technology as a result of his world-conquering.

Before Fuse came to Earth to attack, he once invaded the planet Anur Phaetos, the home planet of the Ectonurites, the same race as Ben's alien form Ghostfreak. They reached an agreement and their planet was spared. Only Vilgax seems to know anything about this agreement, as it is from him that the player learns it from. Fuse eventually manifests an avatar of himself to destroy the player and power up his forces from inside Fuse's Lair. The player however, is able to destroy it after a long difficult battle. However, since the Fuse inside the lair was only an inferior clone of Fuse, Fuse is able to continue the invasion and constantly re-manifests the clone to increase his presence. Due the soon-to-be released Alien X nano, it can be inferred that Fuse is planning his next move, since Nanos are created by defeating Fusions, who are Fuse's strongest soldiers.

The Fuse that resides deep within Fuse's Lair is an incomplete manifestation of him, thus his continued presence as a threat after defeating him. Fuse's castle is split into three sections marked by Fusion Lairs: Fuse's Hall, Fuse's Labyrinth, and Fuse's Throne. Fuse's avatar resides in the latter.
