The In-Betweener

A cosmic entity created by the Masters of the Universe (Lord Chaos and Master Order) to embody duality itself, the In-Betweener exists as the living balance between all opposites—life and death, logic and emotion, reality and illusion—serving as an agent of universal equilibrium.

Few cosmic entities in the Marvel Universe embody a concept as deliciously strange as The In-Betweener — a being born of pure philosophical opposition, conjured from the Bronze Age imagination of Roger Stern and Tom Sutton in the pages of Doctor Strange #27 (1978). Existing at the boundary between all things — life and death, order and chaos, reality and illusion — this enigmatic figure has haunted Marvel's cosmic corners for nearly five decades, surfacing across Silver Surfer, Doctor Strange, and Avengers Assemble. The company he keeps speaks volumes: his path has crossed those of Thanos, Thor, Captain America, and Tony Stark, placing him squarely in the grandest, most universe-shaking stories Marvel has to tell. For readers who love their comics to wrestle with the truly cosmic and the philosophically unnerving, The In-Betweener is one of the Bronze Age's most rewarding deep cuts.
