Dr. Recycle is a recurring antagonist appearing across multiple franchise installments. He operates as a surgeon and scientist in the district called Outside, surgically remodelling humans who abandon their humanity and granting them demonic powers through augmentation.

In the 2019 television series, he continues performing transformations on humans, serving the schemes of larger antagonistic forces within Libra city. His experiments create monstrous entities threatening the populace.

He reappears in the film *BEM: Become Human*, set after the 2019 series events. Here, he operates under primary antagonist Manstoll at Doracho Chemicals. His activities persist in forcibly transforming humans into monstrous forms and conducting research on the main protagonist. While his methods align with his established role as a scientist obsessed with creating humanoid monsters, he undergoes no significant personal development or backstory expansion. His role remains consistent as a secondary antagonist advancing the central conflict through experimentation.

Visually, he is characterized by distinctive multicolored hair, a lab coat, gloves, and frequent syringe use, reinforcing his identity as an experimenter. His flamboyant appearance complements his portrayal as a scientist fixated on his work. His presence across the series and film establishes a pattern of recurring antagonism through unethical experimentation, without substantial evolution in his character arc or exploration of his background, origins, motivations beyond scientific pursuits, or ultimate fate.
