Viktor Licht, a 23-year-old male scientist, stands precisely 187.236 cm tall and weighs 72.358 kg under specific conditions. Born March 14 (Pisces) with blood type AO Rh+, he graduated top of his class in record time from the Imperial University of Tokyo, specializing in Spontaneous Human Combustion and authoring a thesis on the subject. He joined Haijima Industries, becoming head of incendiary research and publishing further work while living in relative isolation. Contacted by Joker, who shared his goal of uncovering hidden societal truths, they formed a clandestine partnership. Affiliated first with Haijima Industries and later assigned to Special Fire Force Company 8, Viktor possesses a distinctive physical appearance: a large, dark-brown curly afro and drowsy eyes lacking visible pupils. He typically wears a long white lab coat over a red-and-white striped vest, dark-green trousers, and red-and-blue sneakers. After joining Company 8, he adopts standard bunker gear but frequently forgoes the helmet. Viktor openly describes himself as a "weirdo," exhibiting mad scientist traits driven by intense curiosity and a relentless pursuit of knowledge. He prioritizes scientific discovery over personal loyalty or ethics, admitting he will switch allegiances if it aids uncovering truths. His fascination with phenomena like the Adolla Burst leads to socially inappropriate behavior, such as crawling to examine Shinra Kusakabe's feet. Despite eccentricities, he demonstrates meticulous planning, analytical thinking, and excitable enthusiasm when observing rare events. Initially distrusted by Company 8 due to suspicious motives and his Joker connection, he gradually integrates into the team while remaining morally flexible, willing to withhold vital information to witness events unfold naturally. Lacking pyrokinetic abilities, Viktor's value lies in his genius-level intellect, chemistry expertise, and tactical acumen. He created explosives from Infernal remains, provided strategic escape routes, analyzed combat dynamics and pyrokinetic abilities in real-time, assessed fire scenes, devised suppression strategies, and supported field operations with scientific expertise. He first appeared indirectly supplying explosives to Joker, disrupting Company 8's operations, and later attended the Rookie Fire Soldier Games as a spectator. Following a government mandate for Haijima scientists to join fire brigades, he infiltrated Company 8 ostensibly to strengthen their chemistry division. His true mission involved spying on Shinra Kusakabe and investigating the Adolla Burst for Haijima, though he personally sought broader truths about the world's mysteries. During the Vulcan's Workshop arc, Viktor intervened in a battle against the White-Clad by igniting explosives and rescuing allies via truck. His timely assistance, followed by Joker's appearance to fend off attackers, heightened suspicions about his loyalties; he deflected Hibana's inquiries about his connection to Joker. In the Nether arc, Viktor identified the White-Clad's hideout through forensic analysis of Infernal outbreaks. He accompanied Company 8 into the Nether wearing full uniform for the first time. Captured by White-Clad operatives, he urged Shinra to use "The Rapid" to escape. He later observed Shinra's battle against Sho, analyzing their Adolla Burst abilities and recognizing Shinra's faster-than-light movement. After Shinra was critically injured by Haumea, Viktor administered first aid and insisted on immediate hospitalization. Viktor's actions show a shift from detached observer to active participant in Company 8's missions. While openly declaring he will side with whoever furthers his pursuit of truth, his actions increasingly align with the team's objectives. He aided Shinra's combat training by conceptualizing flame-condensation techniques and supported investigations into the White-Clad's activities, maintaining his partnership with Joker for shared goals.
