Chemical King

Chemical King is the codename for Condo Arlik, a being born on the planet Phlon who debuted in Adventure Comics #371 (1968) as a Legion Academy student working undercover to infiltrate the Legion of Super‑Villains. Across DC continuities his biography changes with editorial reboots: he was depicted as dying to prevent World War VII in Superboy and the Legion of Super‑Heroes #228 (1977); reappeared as a civilian reporter after the Zero Hour reboot (1994); and is shown among deceased Legionnaires in Final Crisis: Legion of 3 Worlds #1, where his death is treated as restored in some post-Infinite Crisis accounts.

The supplied sources note that Chemical King is an alien from the planet Phlon and was introduced visually in Adventure Comics #371 (1968) with artwork by Curt Swan, but the provided extracts do not give a detailed textual description of his physical features, costume specifics, or coloration. Visual depiction and costume details are primarily available in the comic art of his appearances.

Chemical King's core metahuman ability is to act as a human catalyst, manipulating the speed of chemical reactions. Documented examples include causing iron to rapidly rust or to burst into flames via rapid oxidation, altering chemical reactions in a human to render an opponent unconscious (an effect that takes several seconds and can be focused on a single target at a time), and later displays of affecting rates of energy reactions such as causing batteries to lose power and force fields to decay. Behaviorally, he has served undercover, acted as a Legionnaire, and been depicted as willing to sacrifice himself to prevent large-scale war in several storylines.
