Abigor is a demonic entity with goat-like features and having black wings who only appears in the Club Nintendo comics. He is an ally of Wario and claims to be the "middleman of Hell." During the events of the comic, Mario and many other Nintendo characters live in a skyscraper in Brooklyn, and Abigor has chosen this building to become the domicile for his demonic partners. Wario, being the caretaker of said skyscraper, signs a contract with Abigor that would make him hand over all the keys to the building. In return, Abigor would manipulate Princess Peach's brain, which would make her forget Mario and fall in love with Wario. However, he instead turns her into a zombie.
Once Wario hands over the keys to Abigor, the monsters invade the Nintendo characters' rooms. Mario, Link and Kirby succeed in fighting them back, but when they find that Toadstool has turned into a zombie, they decide to look into the incident. Finally, they find Abigor in his own temple called Infernum. After the monsters are defeated once again, Abigor retreats, announcing he would return (but never actually comes back).
- Abigor bears a surprising resemblance to Baphomet.
