No Face Fagin

In Spirited Away, the original Fagin aids most of the Villain League's ghostly agents, including his "son" Shadow Fagin, in trying to take complete control over the Spirit World and release the forces of darkness that are trapped there. In order to further his scheme, Fagin at first allies with Yubaba, Ratcliffe, and Mr. Krabs, hoping to use their greed to summon greed-orientated heartless to overrun the bathhouse. However, he soon changes his mind when Chihiro/Sen ends up letting a No Face, a type of Dark Spawn spirit that feeds on strong emotions to live and grow stronger, into the bathhouse. Realizing that this creature could provide the perfect vessel for his plans, and to prove to his upgraded son that he too can obtain a super mode, Fagin possesses the creature with a large amount of greed emotions, then fuses with the creature after it absorbs the frog worker, hoping to trick the bathhouse workers into feeding him large amounts of food in exchange for false gold, just so that when they ran out, he would find the perfect excuse to start killing off the workers by consuming them one by one to absorb their hearts to make himself stronger. By the time Sen returned to fix her mistake, Fagin had nearly taken full possession of the No Face, hoping to collect her soul to make his transformation complete so that he could use the Noh Face's powers to unlock the seal of the Underworld and release all the dark forces from the Spirit World and make him their master so that he could use them all to overthrow Mirage and become the ultimate master of the Villain League. However, he didn't count on Sen feeding him the rest of the medicine dumpling, enraging the No Face part so much that Fagin was forced to combine his hatred with that of the monster's, fully transforming them into a mutated hybrid between a raven, a shadow blob, a demon, and a ghost. Fagin, in his fit of drunken madness, tried to kill Chihiro and the Shell Lougers once and for all, but the Real Ghostbusters, having been summoned by Riku's shadow magic, managed to arrive in time, using their Proton Blasters to separate Fagin from No Face, containing all the evil No Face energy within Fagin, and then trapping No Face and Fagin within separate Ghost traps, ending Fagin's plans once and for all.
