Joseph Joestar's grandfather Jonathan, turned into a vampire decades ago.
- Big Brother Instinct: As his final scene proves, he still cares for his adopted brother Dio - enough that he's willing to spend eternity in the afterlife shielding him from his vengeful victims.
- Failure Gambit: What his attempt to carry out the Zero Requiem actually is in a rare heroic variant: to ensure that the canon version of that plan can't be carried out again.
- Hero of Another Story: Went on several adventures in the years between meeting Zeppeli and being turned into a vampire, mainly facing vampires alongside Tonpetty and C.C. or thwarting Dio's assassins.
- Tragic Monster: He absolutely hates being a vampire, especially having to constantly keep an extremely tight lid on his monstrous blood-sucking urges.
- Well-Intentioned Extremist: Wants to save the world, but is willing to use his own version of the Zero Requiem plan to do it.
The Consuls
Rudolph von Stroheim
A German man with cybernetic enhancements.
- Cyborg: As in canon, he has been modified to battle Pillar Men. Naturally, he ends up dueling Jeremiah.
Gyro Zeppelli
A Spin-using man from Naples.
- Sole Survivor: Of JOJO's Consuls. He's last mentioned in the final chapter (having actually survived the whole series) as having started up the Steel Ball Run.
Enrico Pucci
A priest obsessed with gravity, and Dio's right-hand man in another life. In reality, or not; he's actually the same Pucci from canon, having ended up in the current world after his universal reset was interrupted by a strange Traveler.
- Dragon with an Agenda: Initially one of JOJO's Co-Dragons, Pucci secretly has his own scheme to regain Made in Heaven and perform his universal reset on this new world.
- Walking Spoiler: He's an integral part of why the story has even occurred.
The Paladins
Takako Matsuzawa
An elderly Japanese woman with a mysterious deck of cards.
- Misplaced Retribution: Takako blames the Japanese government for getting her family killed during the war with Britannia. She views the resistance as little different, attacking Britannia with little hope of success and inviting retribution upon innocent bystanders, so she tries to kill them first.
- Villainous Breakdown: Goes into a nervous spiral after realizing Lelouch might've switched decks in their duel.
- Warm-Up Boss: Serves as the Kozuki Cell's first experience with Stand users.
Bruford
A Scottish knight who stands against Britannia.
- Adaptational Badass: Didn't possess a Stand in canon.
Tarkus
A towering warrior from Scotland's past.
- Adaptational Badass: Didn't possess a Stand in canon.
- The Brute: A giant fighter who's biggest advantage is combat.
Others
Robert E.O. Speedwagon
A former thug from Ogre Street, he went on to become one of Jonathan's closest friends.
- Adaptational Badass: Unlike in canon, he actually makes use of the bladed hat again, when Dio sends the assassin Render to hill Jonathan. Sadly, it's destroyed after Render becomes a vampire.
- Character Death: By the time the story begins, he's already dead from old age. Or rather, from Rolo assassinating him.
- The Founder: Of the Speedwagon Foundation, one of the biggest organizations in the world.
- Self-Made Man: He and Johnathan discovered an untapped Sakuradite vein in Australia, and laid claim to it (the land ending up in Speedwagon's name). The end result was the beginnings of the Speedwagon Foundation.
- Undying Loyalty: To Johnathan. He was even willing to move to Australia (then little better than a penal colony) just to remain at his side.
Lelouch vi Britannia
Not to be confused with the main Lelouch, this version also started a rebellion against his home nation, but with the power of Geass... only to ascend to its throne as the 99th Emperor. Upon his death, he was shunted into this timeline, where he recruited JOJO to help him to fix the damage he'd inadvertently done to it.
- The Atoner: Basically his only reason for starting up the JOJO faction.
- The Chessmaster: He's ultimately responsible for much of the deviations in the fic, starting from arranging for this timeline's Lelouch to obtain a Stand rather than a Geass, all for the sake of averting the Zero Requiem. This timeline's Lelouch even figures out that he exists solely because JOJO's strategy was exactly what he would've done (and that Nunnally would only lie to him if he told her to).
- Red Baron: The Lemony Narrator refers to this version as the Demon Emperor for simplicity's sake.
- Walking Spoiler: Just knowing about the mere existence of this Lelouch spoils much of the context behind what happens in the fic.
