Nightmare Klonoa is the dark doppelganger of Klonoa in Klonoa: Dream Traveller of Noctis Sol. He captured Lolo in a dream world, posing as the real Klonoa to taunt her and lie to her that he (the real Klonoa) won't return for her. Nightmare Klonoa was then confronted by his real counterpart, and after a battle with them shooting their respective Wind Bullets at one another, Klonoa successfully inflated his evil alter ego, temporarily immobolizing him. In the comic's sudden conclusion, Nightmare Klonoa was summoned alongside Guntz and Chipple by Tenebrae Hue to destroy Klonoa.
