Emperor Nogo manifests as the core antagonist, born from humanity’s collective negative emotions, hatred, and sorrow, endowing him with near-limitless power. He relentlessly pursues the obliteration of all happiness and hope throughout the universe, seeking to impose eternal despair and hopelessness. Initially, Nogo takes the form of a towering clown, featuring a stark white-painted face, piercing red eyes, and an oversized red nose. His black harlequin hat bears five multicolored balls and a purple flame-like aura. He dons a ruffled white collar, a predominantly black suit accented with pink sleeves, and diamond patterns across his torso, an appearance linked to his early revival stages. Sealed by Queen Euphoria of Jubiland after an invasion, Nogo relies on his minions—Ulric, Brute, Brooha, and Rascal—to harvest human negativity. This energy powers the Wheel of Doom, a device critical to his resurrection. His first revival proves fleeting; he is swiftly defeated and imprisoned within an egg-like cocoon. Rascal later sacrifices himself to complete Nogo’s second revival, triggering a metamorphosis. In this evolved state, Nogo grows slender and sprouts bat-like wings. The diamonds on his suit reconfigure into a central column, while his lower attire shifts to light purple with triangular motifs. His sleeves gain prominent white bands and floating purple spiked armbands. This form wields amplified powers, enabling him to summon regenerating Buffoon monsters and the colossal Shadow Giants, entities previously deployed to ravage Jubiland. Nogo’s ultimate form emerges after absorbing the Shadow Giants, transforming into a planet-sized black hole encircled by crimson gaseous tails, featuring a central red maw and eyes. This incarnation unleashes cataclysmic capabilities, such as devouring Earth and emitting gravitational waves that nullify the Glitter Force’s transformations. His assaults include energy cannons capable of annihilating planets and reality-distorting techniques like the "paint of darkness," which traps foes in dimensions of despair. Nogo embodies ruthless cruelty, speaking minimally and favoring direct onslaughts to inflict universal suffering. He displays no loyalty, absorbing Rascal without hesitation to augment his strength. The final confrontation culminates when the Glitter Force, empowered by the Miracle Jewel’s full energy, executes the "Miracle Rainbow Burst," disintegrating his black hole form permanently.
