Pedant, commanding the Star of Darkness, emerges as a multidimensional antagonist whose schemes span manga and anime continuities. In the manga, he orchestrates global chaos by hijacking communication networks, fabricating a drug-induced mass hysteria to destabilize societies. After exposing his own deception as proof of humanity’s inadequacy, he escalates hostilities by unleashing foot soldiers and summoning the Golden Fortress—a colossal invasion weapon later obliterated by Moroboshi. Facing defeat, Pedant ingests a lethal enhancer drug, mutating into a hyper-durable entity capable of firing destructive mouth beams. Though resilient against Ultraman reinforcements, a coordinated strike by Shinjiro, Shin, and Bemular shatters his enhanced form. A surviving fragment defiantly proclaims victory for "justice" before disintegrating. The anime iteration casts Pedant as the architect of the Mass Disappearance Incident, threatening Earth with annihilation unless half its territory or population is surrendered. He wields the Golden Fortress as both command center and doomsday weapon, augmenting his tactical prowess with energy barriers, duplication, and an impervious forcefield breached only by synchronized Spacium Beams. His combat adaptability surfaces through electrical aura assaults and endurance against multiple Ultra suits, culminating in defeat during a united offensive by upgraded Ultras. Across all portrayals, Pedant embodies ruthless pragmatism: exploiting fear, prioritizing technological dominion, and rationalizing conquest through nihilistic ideology. The Golden Fortress persists as an emblem of impending doom, while his willingness to sacrifice his body through drug-augmented metamorphoses underscores a fanatical commitment to destruction. Media iterations remain tightly focused on these core arcs, with no expanded backstory or divergent developments beyond manga and anime narratives.
