Opaque is the main antagonist of Super Smash Bros. Zero, first introduced as Drabuu's loyal servant, and later betraying him for his own purposes. He is one Extermi, meaning he feels the opposite to the humans. He's cynic and sarcastical, mostly because of all his pain. He has a pretty defined personality and appearance, and a great dark aura covering him. He returned as a boss in Fantendo Smash Bros. Uproar, transported with a spell from The Ringmaster, as the penultimate boss.
