The O-Sensei

The O-Sensei is an elderly martial arts master in the DC Universe who trained both Richard Dragon and Benjamin Turner, shaping them into world-class fighters. His profound wisdom and combat expertise made him a foundational figure in DC's martial-arts community.

Steeped in the wisdom of the Bronze Age, The O-Sensei made their mark on DC Comics with a debut in Richard Dragon, Kung-Fu Fighter #1 in 1975 — a landmark launch that itself carries key-issue weight among collectors. This enigmatic figure moves through a compelling corner of the DC Universe, sharing pages with Richard Dragon, Benjamin Turner, and even Robin across a run that stretched into the mid-1980s. Significant enough to earn a place in Who's Who: The Definitive Directory of the DC Universe, The O-Sensei is the kind of foundational presence whose influence ripples outward far beyond a modest appearance count. For fans who love the martial arts–flavored storytelling that made Bronze Age DC so distinctive, this is a character well worth seeking out.
