Jonathan Joestar: zodiac sign and birth chart

Jonathan Joestar is an Aries, born on April 4, 1868. That fits the gentleman who stays polite right up until someone hurts the people he loves. Moon in Virgo keeps the manners tidy, and Pisces Mercury and Mars make him the kind of fighter who would rather win a person over than win a fight.

NEBO's take

Canon says Aries. Our model says Scorpio.

We ran Jonathan through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as water first: slow to anger, deep in feeling, and loyal long after it stops being easy.

NEBO's take

Scorpio SunRead from his personality
  • Sun CanonAriesNEBO's takeScorpio

    Canon gives him Aries: the polite boy who drops the manners and swings when Dio goes after Erina. Scorpio is what lasts after the punch, the loyalty to Erina and Danny that never fades.

  • Moon CanonVirgoNEBO's takeScorpio

    Canon's Virgo Moon is a gentleman in training who copes by being proper and useful. Scorpio feels all of it and says little, so Dio gets away with a lot before Jonathan finally stands up to him.

  • Rising CanonNo birth timeNEBO's takeScorpio

    No birth time in canon. First impression: tall, well-mannered and steady, polite even to the guy picking a fight with him.

  • Mercury CanonPiscesNEBO's takeScorpio

    Canon's Pisces Mercury talks from the heart. Speedwagon starts as the gang boss who jumps him in the slums and ends up one of the most loyal friends he has. Scorpio Mercury sees through people just as fast.

  • Venus CanonTaurusNEBO's takeSagittarius

    Taurus loves slowly and stays. Erina is his first friend and Danny the dog his oldest, and he is loyal to both. Our Sagittarius Venus is the open-handed side, honest about what he feels.

  • Mars CanonPiscesNEBO's takeScorpio

    Canon's Pisces Mars fights for other people, not for himself. Our Scorpio Mars goes all the way once he has decided, and he does not stop until Dio does.

Where we agree: both charts are loyal to the bone. Canon's Aries acts first, our Scorpio holds on far longer, and Jonathan has both.
