Pesky Dust is a unique Ben 10 alien from the Nemuina species of Nemunimos IV, a magical world filled with giant mushrooms and glowing landscapes. Unlike powerful fighters, Pesky Dust uses sleeping dust and dream manipulation to defeat enemies by entering their subconscious minds. His abilities are so terrifying that even Khyber fears him, making Pesky Dust one of the most underrated yet dangerous aliens in the entire Ben 10 universe.
