Marukubi Boon

He is one of Tezuka’s most often-used stars, typically playing a thug or gangsters and commonly appearing as a secondary antagonist or supporting character rather than villain. He is a frequent cohort of Tezuka’s other rogues, such as Skunk Kusai, Acetylene Lamp and/or Hamegg, though generally less intelligent and more prone to direct violence – a trait which often leads to him being used by the others. First appearing in Astro Boy (1952-68), Marukubi Boon as appeared in almost every major Tezuka series, including 14 appearances over the course of Black Jack (1973-83) alone. Modelled after French actor, Lino Ventura, Marukubi Boon is easily recognizable by his thick bull neck, thick black eyebrows and the dark semicircles under his large eyes.
