Vitamin C

Vitamin C (ビタミンC) is the Stand belonging to Tamaki Damo, featured in JoJolion.

Appearance
Vitamin C first appears as several watery hands which leave fingerprints on whatever Damo touches and can spread to others like bacteria. When confronting Norisuke IV and Josuke on his own, Tamaki Damo reveals more of Vitamin C.

It has a vaguely humanoid head with drooping jester horns similar to King Nothing, with a hand-shaped marking on its face. the rest of the body below its shoulders consists of a trailing mass of hand-shaped tentacles, akin to a jellyfish. It is covered with nut shaped objects, some of them chipped in order to resemble the letter C.

Ability
Softening: Vitamin C's main ability is that of "softening" living organisms' tissues. In particular, it can control the elasticity and viscosity of an organism's body to where it can be molded like putty, or the person can lose all control of their body and practically dissolve away and liquefy. For the Vitamin C's abilities to work, the target must come in contact with one of Damo or Vitamin C's hand- or fingerprints.

The strength of the manipulation seems to get stronger as time passes, as Joshu's skin slowly progressed to the point that running water from a sink passed through his head, while Kyo's entire body was turned to liquid and absorbed into the wall by the fingerprints at the time Josuke found her. The power itself doesn't seem to apply to the victim's own Stand, should they have one. Instead, it appears that the Stand becomes immobilized in the same way as its user without losing the respective body part.

Trivia

 * The hand symbol on the Stand's face is Hirohiko Araki's "Hand of the Mangaka".
