OVA
Description
John "Sleepy" Estes patrols New York City as an officer in the NYPD's 34th Precinct. Associates call him "Sleepy," while criminals dread him as "Mad Bull." He commands attention with his towering, muscular frame and sharp chevron mustache.

At fourteen, gangsters murdered Estes' family, igniting his lifelong crusade against New York's organized crime, especially gang leaders. He enforces justice through extreme violence—summarily executing thieves and rapists with close-range shotgun blasts—and routinely flouts police protocols.

Despite his brutality, Estes reveals layered motives. He controls prostitution in his precinct, soliciting workers and seizing their earnings to fund charitable clinics for sexually transmitted diseases and shelters for abused women. Unexpectedly, he shows tenderness toward animals and protects the vulnerable, erupting in rage when criminals abuse creatures like attaching guns to cats. He also hesitates to harm children, even under threat.

Functioning as an anti-hero, Estes blends corruption with flashes of nobility. His partnership with the more by-the-book officer Daizaburo "Eddie" Ban creates friction; Ban initially questions Estes' methods but grows to respect their effectiveness against entrenched crime. Estes demonstrates cunning through meticulous traps and hidden weapons, like converting apartment pipes into shotguns or taping grenades to his pubic hair for emergencies.

His resilience nears superhuman, surviving point-blank shotgun wounds and improvised bombs that would kill others. This durability fuels his fearsome reputation, making him a constant target for criminal assassins. Within the police hierarchy, Estes clashes with superiors over his tactics yet retains protection due to his success against high-level threats. Lieutenant Perrine Valley occasionally aids him and Ban during complex organized crime probes.

Estes' persona persists unchanged across the original manga (1986-1990), the OVA adaptation (1990-1992), and the sequel *Mad Bull 2000* (1999-2002), where he employs identical brutal methods against new adversaries.
