Craniac is an alien who teams up with Verminator-X in the Dreamland storyline of Eastman and Laird's Teenage Mutant Ninja Turtles Adventures. As there are certain alien species incapable of dreaming, they will pay to have memories of individuals who have lived interesting lives used as their dreams, and will pay a higher price for the more unique or exciting ones. This process involves harvesting an individual's brain, and Craniac proposes that he and Verminator acquire a very specific brain - that of Austrian-German dictator Adolf Hitler. After the Future Mutant Ninja Turtles retrieve Hitler's brain, Craniac and Verminator take it from them. They then later confront the Turtles and Craniac decides to take their brains, hoping they'd get a reasonable sum for them, when Verminator turns on him, as the agreement was to only harvest the brains of those that were already deceased. Craniac flies off in his spaceship and leaves Verminator to die when the impending comet hits the Earth.
