Vitamin C

Vitamin C (ビタミンC) is the Stand belonging to Tamaki Damo, featured in Part VIII: 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, revealing its humanoid figure with several C-markings on it.

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 loose 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 handprints or fingerprints. The strength of the manipulation seems to get stronger as time passes, as Joshu's skin slowly progressed to the point that water from a nearby sink passed through his head while Kyo's entire body was turned to liquid and absorbed by 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 appearance of the Stand itself could be a reference to the dozens of severed hands that drag away Yoshikage Kira at the end of Part 4.
 * The Stand's abilities are similar to Spice Girl, but only applicable to living bodies.
