Death Thirteen

Death Thirteen (死神13（デスサーティーン）) is the Stand of Mannish Boy, an antagonist featured in Part III: Stardust Crusaders.

Appearance/Personality
Death Thirteen appears as a mix between a clown and the Grim Reaper holding a scythe. In place of a skull, it has a clown face with downwards curved eyes and an eerie smile. The face's design takes inspiration from the masks found during the Venetian carnival. Its mouth never moves as it talks, though it can move its mouth and face independently. Outside of its head and arms, Death Thirteen has no physical body, meaning any attacks aimed at its clothing simply passes through the emptiness under its mantle. This gives it immunity to most bodily attacks, even those launched by a Stand. Death Thirteen is also an extremely unique stand in that it is controlled by an 11 month-old User. It represents the Tarot Card Death.

Ability
Master of Dreams: This ability comes in two parts. When anything alive (human or otherwise) falls asleep near Mannish Boy, Death Thirteen's User, they are drawn into Death Thirteen's dream world, which appears as a massive carnival, complete with Ferris wheels and roller coasters. Death Thirteen has full control in this dream world, save for the people drawn into it. It is able to make death machines out of mechanical items, make objects out of nothing, or even trick a person into thinking they have summoned their Stand, though this is actually Death Thirteen, as nothing besides those who are asleep can enter Death Thirteen's world.

Any injuries the person receives in the dream world are transferred to the real world, including fatal ones. The corpse of anyone killed stays where it was killed in the dream, becoming a part of it, and thus under Death Thirteen's control. If, by some miracle, the person manages to survive Death Thirteen's assault, they forget what happened when they wake up, and only remember once they return to Death Thirteen's world. This makes it very hard to attack the relatively weak User. The only way someone may remember what happened in the dream world is if they sleep with their Stand active beforehand. Only that way will the person be able to summon the Stand inside the dream.
