02Appearance
03Personality
Above all else, Jack the Ripper detests women who are enjoying themselves. As such, he takes immense pleasure in his murders of unarmed victims, cutting out their organs with a scalpel and hanging them on nearby walls. However, Jack is also meticulous in his actions, using a gentlemanly facade to seduce his victims until he can safely perform the deed. Unexpected hinderances have been shown to unsettle the killer, and his murderous tendencies can easily be turned toward witnesses to his heinous actions if need be, as seen when he attempts to kill Dio Brando.↗↗
As a zombie, Jack's already-disturbed personality becomes even crueler. Rather than murder itself, the zombified Jack now takes pride in his victims' fear and despair, to the extent that he is willing to harm himself without hesitation to invoke it. Jack's instrument of choice remains the scalpel, though he is quick to improvise with other sharp weapons. He also retains his former cunning, and is capable of using his surroundings to isolate and terrify his victims. Even after being seriously injured by Will Anthonio Zeppeli 's Ripple energy, his outburst of anger does not prevent him from devising a plan to further separate his victims.↗↗↗↗
04Abilities
After being turned into a zombie, Jack becomes even more brutal than he was as a human. The zombified Jack is not only unable to feel pain, but also has incredible speed: he is shown to be able to kill a man, decapitate two horses, and hide inside the body of one horse in a matter of seconds.↗
05Story
SPOILERS
Phantom Blood
After killing his final victim as a human, Jack was approached by a then-incapacitated Dio Brando who saw the evil in the man's heart and decides to make him one of his zombie minions. Refusing at first, Jack accepted after a failed attempt to kill Dio. (In the anime, Dio instead hypnotizes Jack to come forward so that the former could suck his blood to turn him into a loyal zombie servant.)↗↗
Later, he corners Jonathan Joestar, Robert E. O. Speedwagon and Will Anthonio Zeppeli in a tunnel on their way to Windknight's Lot, decapitating their coachman along with the horses as he hid in one of them. Once revealing himself, Jack proceeded to throw the coach wagon into the mouth of the tunnel to prevent Jonathan and his companions from escaping.↗↗↗
