Poison

Poison is a young man whose complexion runs dark while his hair stays pale. His everyday black outfit carries his name across it, with skull motifs trimming both the sleeves and the collar.

Direct to a fault, Poison says exactly what he thinks and openly brands Sekingar a liability. Beneath the bluntness sits a real concern for his fellow heroes, and he checks whether anyone has been hurt. He also holds a clear-eyed view of his own ceiling as a C-Class fighter; after watching Brave Giant unleash a massive energy blast, he decides his usefulness has run out and figures he may as well head home.

Poison is among the heroes Sekingar recruits for the support unit tasked with storming the Monster Association hideout. In the thick of the fighting, he steps in as a monster chases Sekingar and slashes the creature with a poisoned blade. Sekingar protests that the cut looks too shallow to be fatal, but Poison notes the wound runs deep enough for his toxin to take hold. The monster soon convulses, foams at the mouth, and gasps for breath as its veins bulge, before Sekingar finishes it with his Executive Beam.

He stays on the surface while the S-Class heroes push into the enemy base. When Brave Giant unleashes the Millennium Emperor Nova, Poison finds himself caught in the shockwave yet keeps his composure, glances at his knife, and concludes that going home is the wiser move. The support team later shields Waganma during their escape, but Nyan tears through the group and defeats Poison along with the others; Sekingar carries him to safety, and he is still drawing breath by the time Drive Knight destroys the monster. Afterward he stands among the crowd of heroes debating the fate of the beaten Garou, until King's arrival cuts the discussion short.

His poisons can kill monsters so long as he lands a cut to deliver them, and he favors a no-frills karambit knife, insisting there is no call for showy technique.
