Loccobarocco oversees Green Dolphin Street Prison, a maximum-security facility, with meticulous authority. His communication hinges on Charlotte, an alligator puppet wielded to engage inmates and staff. Charlotte frequently snaps with irritation during interruptions, mirroring his insistence on disciplined order during interactions.

Physically, he sports a compact, stocky frame, accentuated by bulbous circular mounds encircling his eyes and a sharp, bottle-like protrusion crowning his head. A sparse tuft of hair sits above his forehead, contrasting his otherwise bald scalp. His uniform—a badge-studded collared shirt, tie, and dress pants—is accessorized with practical details like pocket pens. Charlotte, adorned with a bowtie, occasionally channels an antiquated American visual style in certain adaptations.

Tasked with enforcing regulations and mitigating crises, he first appears delivering a vengeful letter from Jolyne Cujoh to her lawyer. When two inmates vanish under mysterious circumstances, he mobilizes a search team, deliberately selecting Jolyne to participate—a choice that inadvertently entangles her in escalating prison conflicts.

A minor trivia note highlights the French Tonkam manga edition’s incongruous gender misidentification of him, underscoring occasional localization inconsistencies without altering his established canon portrayal.

Across official narratives, his role remains anchored to administrative rigor and operational oversight, devoid of personal history. Charlotte’s presence cements his eccentric command, merging rigid enforcement with an unorthodox communicative flair.
