Stubb was a treacherous pirate who helped Captain Jack Sparrow retrieve the Skull of Teoxuacata from Fort Alvo Grande in Panama. After discovering the location of the skull, Stubb and his associate knocked out Jack and his companion, William Turner, and absconded with the skull themselves. After Jack escaped from the fortress, he returned to Tortuga, finding Stubb and his associates as rotting corpses. Jack attempted to retrieve the skull, but Stubb awoke and attacked him. It is not known what happened next.
