20th Century Boy is a stand obtained by using a Holy Corpse on standless. You have a 40% chance of getting this stand from the Holy Corpse.


20th Century Boy appears generally like a hollow piece of armor, composed of a headpiece, two large shoulder pads from which hang two long, branching straps, and a shell at its back from which grow two more comparatively plain straps. Blank-eyed, its head bears two long, vertical antennae; a bolt runs through it from shoulder to shoulder; and it is marked by a motif resembling a small hand of three simple fingers, both on its head and at every end of its branching straps.

20th Century Boy is purple and cyan in the colored manga.
