Dark Vegan is an alien from the planet Vegandon on Johnny Test. He is the location's leader. Dark Vegan wants to deplete Earth of all its resources. He absolutely loves toast (which Vegandon does not have) to a point of obsession, and would do anything for it. Dark Vegan has a rebellious daughter, Jillian, who wants to go back to Vegandon, and a wife, Mrs. Vegan, who likes it on Earth. He is an antagonist in the series, and because of this, he was defeated by Johnny himself many times. Dark Vegan is a parody of Darth Vadar.
