Character from One-Punch Man by ONE & Yusuke Murata
S-Class Rank 6 — a weapons developer who sends drones to fight while he sits safely in his laboratory, and whose real agenda has nothing to do with heroism.
Metal Knight (Dr. Bofoi) is the Hero Association's most controversial member. He fights entirely through unmanned drones, never risking himself. His real interest is weapons development — he uses monster attacks as live testing for new military technology. He built the Hero Association's new headquarters (and probably installed backdoors in it). Drive Knight considers him dangerous. The series hasn't confirmed whether he's a secret villain or just an amoral pragmatist.
His combat drone is a large, heavily armed robot. Bofoi himself is rarely seen — an older man in a lab coat. The drone is imposing and militaristic, bristling with weapons.
