Henry Jacobs/Mr. Hyde is the main antagonist of the Thunderstorm series created by Sote Tariah. Henry Jacobs is a brilliant but corrupt biochemist who built his empire by creating illegal performance‑enhancement drugs for the criminal underworld. When his lab was raided, he drank an unstable prototype serum in a desperate act of ego and defiance. Instead of dying, he mutated into a powerful, green‑skinned monster with immense strength, near‑zero pain response, and a warped, theatrical personality. To hide his inhuman form, Henry wears a waxy, uncanny replica of his old face — a mask he treats like a prop rather than an identity. Personality: Bombastic, dramatic, and dangerously charismatic. He speaks in declarations, fights like a spectacle, and treats chaos as performance art. Beneath the theatrics lies a ruthless, cunning mind. Motivation: Henry sees Thunderstorm’s restraint and morality as a personal insult. He wants to break him — physically and philosophically — to prove that chaos is the true nature of humanity.
