Character

Mannish Boy

マニッシュ・ボーイ

Mannish Boy is a minor antagonist featured in the 3rd part of JoJo's Bizarre Adventure, Stardust Crusaders, specifically the "Death Thirteen" story arc. Mannish Boy is an evil genius baby and Stand user in DIO's service. He tries to murder the Joestar Group inside the nightmare-world of his Death Thirteen. Mannish Boy is an impossible genius; able to, although a baby, think like an adult. He is able to defend himself from a scorpion and is even seen smoking. When close to people, he tends to act like a normal baby in order to avoid attention. He only shows his true personality when his victims fall asleep close to him; allowing him to use his Stand, Death Thirteen. Through the Stand, disturbingly, Mannish Boy speaks easily, swearing and mocking; while still acting childish. He is also rather sadistic in killing his targets, prone to fits of maniacal laughter (written as a childish "hehehe") and boasting, though his overconfidence can betray him. Mannish Boy may be one of the most sadistic and disturbing characters in the series, showing no respect for human life, and enjoying torturing its victims instead of killing them outright, despite being only a baby.
