Awful Alvin is one of the main antagonists of the animated series LarryBoy: The Cartoon Adventures. He is one of LarryBoy's dangerous enemies. He also appeared in both the episodes and the books of The Angry Eyebrows as the main antagonist, The Yodelnapper as a background villain, and The Good, the Bad, and the Eggly as the secondary antagonist.
Alvin considers himself the "most awful mind of all time" potentially because of his name, and tries to prove it by creating evil schemes, inventions, and minions, which included: The Angry Eyebrows, the Overeasy-Egg-Ray, and his fake and silent sidekick named Lampy. Alvin is known for his signature "Villainous Dance of Villainy" and evil laugh, which he sometime uses randomly. Alvin was being hyperactive when he was being evil (that is to say, all the time).
He was voiced by Larry Whitaker in his first villainous role of LarryBoy: The Cartoon Adventures, Willem Dafoe in Larry-Boy: A VeggieTales Movie, and currently Sean Chiplock in The VeggieTales show and The Universal Studios Show.
