Rubber Soul (ラバーソール, Rabā Sōru) appears in Stardust Crusaders as the central antagonist of the arc Yellow Temperance.
Impersonating Kakyoin, Rubber Soul isolates and attacks Jotaro and Anne in Singapore.
Rubber Soul has dark, curly hair and a muscular build. His Stand grants him the ability to grow larger and to change appearance at will.
Rubber Soul was hired by DIO with the promise of earning 100 million dollars as a reward for killing Jotaro.
He has a rather disturbing personality: he is extremely rude and impolite, showing no respect or mercy for people and animals, as they are beings that he only sees as food for his Yellow Temperance. He does not seem to be particularly intelligent. He is easily angered. He wanted to ambush Jotaro with Kakyoin's appearance, but his unusual behavior blew his cover. He is also narcissistic and arrogant, referring to himself as handsome and believing his Yellow Temperance has no weaknesses, taunting Jotaro and bragging about his abilities while underestimating Jotaro's abilities.
Rubber Soul is also very violent; he attempts to kill a pickpocket by breaking his back and remorselessly eats a dog under the eyes of its master with his Stand. In order to grow bigger, he did not hesitate to eat even bugs.
In spite of this, he is very cowardly, giving away the names of his allies in order to escape Jotaro's wrath and having a strong fear of being hit or hurt in general.
Rubber Soul's Stand is Yellow Temperance; a sticky, rubbery mass bound to and encasing his body. It defends him from all brute attacks, and allows him to effectively impersonate others.
While the Joestar Group are in Singapore looking for tickets to travel to India, Joseph and Avdol decide to anticipate DIO's next move. Joseph uses Hermit Purple on a television, trying to get any information he can. Before being able to locate DIO, his Stand warns its master about the coming danger: by joining voice segments from different TV programs together, Hermit Purple informs the two about Kakyoin being a traitor.
However, Joseph's stand actually presages Rubber Soul's presence and modus operandi, since he secretly uses his Stand to take Kakyoin's appearance and ambush Jotaro while he is alone with Anne. Jotaro begins to be suspicious about "Kakyoin"'s strange behavior. When Rubber Soul tries to push him from a balcony, Jotaro believes Kakyoin to be possessed and punches his face.
After hitting him, Rubber Soul's real power is revealed. Being unable to destroy Yellow Temperance by burning and freezing it, Jotaro drags Rubber Soul underwater, taking advantage of the wielder's human frailties to defeat his Stand. Jotaro punches a now defenseless opponent, forcing him to reveal the power of J. Geil's Stand.
Rubber Soul tries to finish Jotaro with a last surprise attack, but Jotaro manages to counter it by exploiting water pressure. The now defeated Rubber Soul tries to save himself by saying that he was just kidding, but Jotaro replies by saying "Kidding? Then let's laugh together" and proceeds to attack him with countless punches by Star Platinum. It is unknown if Rubber Soul was actually killed in the process.
In the game, Rubber Soul instead briefly imitates Devo and battles the player's group on a hotel rooftop.
Rubber Soul is one of several characters added in the arcade update. Looks-wise, he is a palette swap of Kakyoin with a taller build and a different face, and his Stand is a yellow-coloured Hierophant Green. He is not encountered in the Story Mode by any of the main characters (arcade version), but retains his own storyline as a secret character.
In his own story, Rubber Soul is hired by DIO to assassinate Jotaro and his companions. His story lacks any notable cutscenes aside from the ending after the player defeats all of the heroes. He claims that he is the luckiest man in the world, and that no one else could earn one hundred million dollars by fighting for only a few minutes.
He is also encountered as a normal enemy in the PSX port's Super Story Mode. The Player will receive a Secret Factor bonus if they allow him to perform his "Rero rero rero" taunt.
Rubber Soul might essentially be a palette swap of Kakyoin, but his playstyle differs greatly. He lacks an active Stand, and instead elects to call Yellow Temperance to the battlefield temporarily for his special attacks. His moves tend to be slow and clumsy, as he cannot block or perform any follow-up attacks (aside from his light punch) while Yellow Temperance is still visible on the screen.
His special attacks involve Yellow Temperance (in the form of a yellow-colored Hierophant Green) shooting yellow acid balls at the opponent in short range. Within that same range, he can grab the opponent and break their back over his shoulders. He can also throw Yellow Temperance along the ground to ensnare the opponent's legs.
His special Stand technique allows Rubber Soul to counter an oncoming attack by forming a rubbery shield around his torso and knocking the opponent airborne. This is commonly followed up by his first super technique.
Rubber Soul's intro mimics a scene from his initial appearance, during which he eats several beetles and grows in size, making the sprite different from Kakyoin's. Also, if Alessi uses his Stand power on him, Rubber Soul does not turn into a child, but rather reverts to the fat woman he took the appearance of in the cable car.
Rubber Soul appears as one of the several PART III characters who possesses a Metal Striker. His FINISH MOVE makes the enemy get enveloped by Yellow Temperance, which melts and causes damage.
