The Shadowmaniac is an evil version of the Infomaniac. The Shadowmaniac was created when Happy-Go-Lucky Business Man attempted to control the Infomaniac's mind after capturing him. Although the Infomaniac held his own against Happy's mind control bear Teddy Bear, the stuffed bear altered the Infomaniac's mind, giving him super strength and an evil personality. The Shadowmaniac was introduced when Pepper Roni had defeated every other mindwiped minifig.
