Nemo

Nemo is the primary and titular protagonist of the Japanese/American animated film, Little Nemo: Adventures in Slumberland, based on animator/cartoonist Winsor McCay's famed 1905 comic strip. A young boy who has vivid dreams, he was chosen by the playful King Morpheus of Slumberland to be his successor and the playmate of Morpheus' daughter Princess Camille. However, at the urging of the imp Flip, Nemo accidentally released the demonic Nightmare King, who tried to take over Slumberland before Nemo and his companions stopped him. When the King returned and joined the forces of Maleficent and the Horned King in Heroes vs. Villains War, Nemo once again joins the fight to protect both the waking and dreaming worlds.
