One Piece Odyssee

Impel Down is the world’s most infamous prison, located deep within the Calm Belt and designed to house the most dangerous criminals in existence. The prison is a complex of underwater levels, each more secure than the last, with terrifying guards and deadly traps. It is managed by the World Government and is the last stop for many pirates and criminals before facing execution or being thrown into marine hell. The prison is known for holding some of the most notorious figures in the world, including dangerous pirates, revolutionary leaders, and traitors. Impel Down plays a critical role in maintaining the power of the World Government, as it serves as both a deterrent and a storage facility for those deemed too dangerous to roam free. The very structure and isolation of the prison make it a fortress of security that is nearly impossible to escape from.
