Vasco Shot is a large member of the Blackbeard Pirates. Known as “Mighty Drinker” Vasco Shot (大酒のバスコ・ショット, Ōzake no Basuko Shotto), he was one of the legendary criminals who was given a life sentence in Level 6 of Impel Down. Their crimes were so atrocious that they were effectively erased from history itself. He was initially mentioned briefly by Emporio Ivankov.
