JoJo no Kimyou na Bouken Part 3: Stardust Crusaders

Synopsis

Jotaro and Anne suspect something is wrong with Kakyoin after observing some odd characteristics, such as brutally beating up a thief, eating beetles, and licking a cherry in a disgusting manner. After nearly being pushed off a balcony at the cable car station, Jotaro, believing Kakyoin to be possessed, punches him, revealing him to be an impostor. Rubber Soul, one of Dio's assassins, reveals he has disguised himself using his Stand Yellow Temperance, a Stand that consumes flesh and can take on any form. As the two take their fight onto the cable cars, Anne reports the situation to Joseph and Avdol, who are shortly joined by the real Kakyoin. Rubber Soul reveals that a piece of Yellow Temperance's slime has come off onto Jotaro's hand when he punched him, stating it will slowly consume his flesh. Failing to remove the slime with both fire and ice and after being ambushed by Rubber Soul again who claims his Stand is invincible, Jotaro instead decides to drag him down into the sea below, forcing Rubber Soul to lower Yellow Temperance's guard to breathe and leaving him open to a direct attack. Upon being interrogated by Jotaro, Rubber Soul reveals the Stands of Dio's next assassins are Death, the Empress, the Emperor, and the Hanged Man; the last of which is J. Geil, the man with two right hands who killed Polnareff's sister. In a last ditch attack, Rubber Soul uses a nearby drainage pipe to deliver one last attack against Jotaro, only for him to use the very same pipe to have Star Platinum deliver a high pressure water blast right back at him. After deeming Rubber Soul of no further use and pummeling him, Jotaro rejoins the group as they continue their journey to India, becoming surprised when Kakyoin licks a cherry in an identical fashion to his imposter. Unbeknownst to the Joestar group, Anne is following them in the next train car.
