Biyo is a young boy who was imprisoned in the Biscuits Room on Punk Hazard. He's best known for being one of the kids caught up in the island's dark experiments—held captive alongside other children in what became a major plot point during the Straw Hat crew's arc there. The Biscuits Room itself was basically a prison within the larger facility, where he and the other captives were kept under brutal conditions.
