Stimulus

Dark Horse’s Stimulus launched in 2026, a single-issue comic that immediately stakes its claim as a taut, self-contained thriller. The series follows a desperate man who signs up for a mysterious experimental treatment promising to cure his anxiety, only to discover the procedure has terrifying side effects that blur the line between reality and paranoia. Written with a lean, claustrophobic intensity, this debut issue introduces a world where modern mental health solutions come with a sinister price, making it a sharp, unsettling entry in Dark Horse’s tradition of psychological horror.
