A surprising and laugh-out-loud showdown between two pint-sized super-villains, perfect for young fans of Despicable Me.

Dylan's parents, Mr. and Mrs. Snivels, have always told him that he is the very best and cleverest super-villain in the whole wide world. And Dylan's confident that it's true--until he starts school and meets Addison Van Malice. Sure, Dylan's costume is scary. But Addison Van Malice's is bone-chilling. And yes, Dylan's laugh is crazy. But Addison Van Malice's is bananas. And Dylan's inventions are certainly super-villainous. But Addison Van Malice's are demonic! When their teacher, Ms. Ick, announces a Diabolical Robot Building Contest, Dylan sees his opportunity to prove that he really is the most evil villain of all. But Addison's not giving in without a fight. And so begins a competition of skill and wits that doesn't go the way anyone expected...
