~ Mannish Boy

Mannish Boy is a minor antagonist from JoJo's Bizarre Adventure: Stardust Crusaders. Mannish Boy is a eleven-month old baby, who controls the Stand known as Death Thirteen, which attacks people on their dreams.

In Japanese, he was voiced by Miki Nagasawa in JoJo's Bizarre Adventure: Heritage for the Future and Ikue Ohtani in the anime. In the latter's English dub, he was voiced by Tara Sands.


Originally, Mannish Boy is found near a well by a woman, who takes him near Jotaro and his group, apparently subconsciously guided by the baby. He first attacks Kakyoin while he sleeps, as well as a dog. Kakyoin finds himself on a ferris wheel in an amusement park along with the dog, where Death Thirteen attacks him and kills the dog, after which Kakyoin is awakened by Polnareff. Upon awakening, Kakyoin forgets about the dream, only remembering a baby cry.

Kakyoin leaves the hotel the group stayed, after which he and Polnareff see a dead dog, just like the one in the dream. The group rent a airplane to cross the Arabian Desert, but they are forced to take the baby with them, which has a high fever. Inside the airplane, both Polnareff and Kakyoin fall asleep, so they are immediately transported inside Death Thirteen's nightmare. Death Thirteen attacks the two, who are unable to call their own stands, and when he is about to kill Polnareff he is awakened by Joseph, who tells him to change the baby's diaper. Kakyoin, still trapped in the nightmare, is attacked by Death Thirteen, but he starts debating himself, causing Joseph to lose control over the plane, which plummets down. During their conversation, Kakyoin finds out the baby is the stand user, but he is trapped by Death Thirteen, so he draws his pocket knife and stabs his own arm in an attempt to wake up, which fails. As the plane crashes on a palm tree, Kakyoin wakes up, disoriented.

While the group mounts a camp for the night, Kakyoin notices his arm is bleeding. He sees the word "BABY STAND" written on his wounds, and starts getting suspicious of the baby. He he looks at him, the baby turns his head away, so Kakyoin grabs the baby, but Joseph stops him. A scorpion gets near the baby, but he uses the nails on his diaper to kill it, which Kakyoin sees. Kakyoin attempts to alert the group about the baby, but he is knocked down by Polnareff before attempting to hurt the baby, as they believed Kakyoin was hallucinating.

The group goes to sleep, so they are all transported into Death Thirteen's nightmare. He starts messing around with them, even creating a fake Star Platinum when Jotaro attempts to call his Stand. Just then, Death Thirteen is attacked by Hierophant Green. Kakyoin shows up in the dream, revealing he kept his Stand activated before fainting, and as such he was able to call it inside the dream. He attempts to strangle Death Thirteen, who uses the clouds to grab his scythe and attack itself an an attempt to strike Hierophant Green, revealing that it has near no body. However, Hierophant Green unravels itself and enters Death Thirteen's head through its ear, who is left defenseless.

When the group wakes up, they see Kakyoin, apparently recovered, taking care of the baby while still remembering the dream (and the only member of Joestar group to remember the dream). Kakyoin, although he wouldn't maim or kill Mannish only because he is still a baby, nevertheless warns the kid to return to his mother and to never get near them again, after which he gets the baby's poop and mix it on his food, which Joseph forcefully feeds him.

Powers and Abilities

Death Thirteen

Lali Ho! It's romantic, wouldn't you agree? Being able to die in a dream?
~ Death Thirteen

Whenever someone sleeps near Mannish Boy, they are immediately transported into Death Thirteen's dream world. Death Thirteen has complete control over everything inside the dream, and as such it's victims are left defenseless. If the victim somehow wakes up, it will forget completely about the nightmare. Since Death Thirteen keeps the victim's spirit on the same state as when they go to sleep, Stand Users are unable to call their Stands inside the dream, unless they keep it activated before sleeping, since Stands are manifestation of one's spiritual power.

Death Thirteen appears as a Grim Reaper-like figure wearing a clown mask and holding a huge scythe. Beneath his cloak is completely hollow, as Death Thirteen is composed of only a head and floating arms.



  • In the Super Famicom video game adaptation of JoJo's Bizarre Adventure: Stardust Crusaders, Mannish Boy instead attacks the Stardust Crusaders on a plane heading to India.
  • Mannish Boy originally had no name, and was only given one in the art book JOJO A-GO!GO!.
  • Oddly, despite not being related to the Stone Mask Vampires, Mannish Boy noticeably has large fangs.
  • Death Thirteen's abilities to drag people inside and kill them in dreams might be a reference to Freddy Kruger's abilities, which are a near-exact replica of.
  • Death Thirteen's signature phrase, "Lali Ho!", is a reference to the Dragon Quest spell of the same name.
  • Unlike the other Stands with names hailing from the major tarot arcana, Death Thirteen resembles its design on the card perfectly.
