Tatoo You!

Tatoo You! (!) is the shared Stand of the Eleven Men, featured in Steel Ball Run.

Appearance
Tatoo You! takes the physical form of black graphics resembling tribal tattoos across the back of each of the Eleven Men's heads. Each member also has a small white mask in the middle of these markings as well, resembling a face with closed eyes and a neutral expression.

Ability
Tatoo You! functions as an ability shared between all of the Eleven Men, greatly enhancing their teamwork and defense. This Stand is largely unique in the scene that it is controlled by eleven individuals, although shared Stands have been seen before such as Tomb of the Boom, it still holds the record for the largest amount of users for the same Stand by a significant amount. The Stand's official description suggests that there is a leader amongst the men who may be the main owner of Tatoo You!, but it is unknown who it could be. After the death of ten of the eleven users, it is likely that Tatoo You! no longer retains any effective uses for the surviving member, this is due to the fact he would have no way to travel between his fellow users without physically bringing their corpses with him everywhere.

Body Slide
Tatoo You! allows the Eleven Men to phase into each other by using the tattoos on their backs as portals, then reappearing through the tattoos at will. The men can exist in the same spot all at once, appearing as if they are merged together.

It allows the men to hide inside each other in order to avoid attacks. Even if a member of the group dies with companions inside, those inside the tattoos are unharmed and can move the bodies to position themselves to attack.

Trivia

 * Tatoo You!'s design may have been inspired from a type of tattoo that Araki saw somewhere once.
