Roidmude 009 (ロイミュード００９, Roimyūdo Zero Zero Kyū), self-titled the Medic Roidmude (メディックロイミュード, Medikku Roimyūdo), or just Medic (メディック, Medikku) is a healer-based Roidmude who took on the appearance of ballet dancer Misuzu Hatori and appeared to assist Heart after the events of the Global Freeze.

Medic, originally designated as Roidmude 009, was among the Roidmude combatants that made their attack during the Global Freeze. During the event, she found the unconscious body of Misuzu Hatori, a ballet dancer who survived a murder attempt by Kazuya Igarashi. Roidmude 009 assumed her human form and evolved into the Medic Roidmude, granting her ability of healing. As a sign of good gesture, she used her powers on Misuzu and her pet dog Shou.

Medic would use her newfound abilities to restore the defeated Roidmudes, allowing them a chance of victory against Protodrive. While she innocently healed her comrades, her powers also came with the side-effect of absorbing their negative emotions, which eventually corrupted her personality and rendered her comatose for the next several months.

Despite her kind facade and loyalty to Heart, she actually has her own agenda, which Heart and the others are unaware of. She is far more cruel than any of the inner circle Roidmudes in solving things, revealing to Shinnosuke that she never cared for any Roidmudes other than Heart, and finds disposing of defective Roidmudes a more efficient alternative to resetting them, taking her new Grim Reaper role with psychotic zeal.
