Operating in the realm known as Outside, Dr. Recycle is a mysterious surgeon and scientist. He specializes in remodelling disillusioned humans who choose to abandon their humanity, both internally and externally. Through his experiments, he grants these subjects demonic power, transforming them into monstrous entities and facilitating their transition into beings with supernatural abilities.

He possesses multicolored hair and is often depicted wearing gloves, contributing to a distinct, flamboyant appearance. His enigmatic persona offers no revealed personal history, origins, or underlying motivations. His activities consistently focus on recruiting and transforming humans, positioning himself as the conduit for their acquisition of monstrous power.

Dr. Recycle appears as a secondary character in both the 2019 anime "BEM" and the 2020 film "BEM: Become Human", providing demonic transformations. Within the film's setting of Doracho Chemicals, a city-island, his function remains unchanged. Across these appearances, he undergoes no significant evolution, backstory exploration, or personal development. His actions solely revolve around enabling the abandonment of humanity through scientific and surgical means, without elaboration on his own history or any shift in his objectives.
