Doctor Black Beard is a doctor who appeared in Ace's mini-story.

Appearance
Doctor Black Beard is a rotund man with relatively thin limbs. Like Marshall D. Teach, he has fluffy black hair with the top tucked in by a bandana. He also has a goatee. The doctor wears round glasses, a white a-shirt with a cross on the front, striped-patterned pants, white shoes, a doctor's coat with his name "Dr. Black Beard" on the left side, a medical cross on each side of the collar, and carries a pen in the right breast pocket of the coat.

History
Ace mistook him for the real Blackbeard and kicked him to the ground, much to the fury of everyone else around them. When Ace saw his mistake, he was kicked into the river by the angry Doctor Black Beard, an angry cook (whom Ace did not pay for his meal from earlier), and other spectators who were furious at Ace's attack.
