Jonathan Joestar

Jonathan Joestar is the protagonist of Phantom Blood and the first JoJo of the JoJo's Bizarre Adventure series.

He is characterized as being kind, honest, and loyal, as a direct counterpart to his adopted brother, the evil Dio. He sacrifices himself at the end of Part 1 in order to defeat Dio, but his sacrifice was in vein, as Dio was able to survive and attach his severed head onto Jonathan's post-mortem.

Jonathan fathered one child with his wife Erina before his death, George Joestar II, and through DIO using his body to procreate, is technically the father of Giorno Giovanna, Rykiel, Ungalo, and Donatello Versus.

Physical Appearance
Jonathan is a large physically fit man. He has blue longish hair and blue eyes. His usual outfit consists of him wearing a large blue short-sleeve crop top. He wears a backpack and grey jeans with brown boots.

Occasional Appearances
In Dio the Invader, as a 12 year old boy, he has well kept blue hair and wears a fancy suit over a white undershirt.

In Dio the Invader, as an adult playing rugby he wears a large long sleeved jersey with white and aquamarine stripes.

In A Letter From the Past, when confronting Dio about poisoning their father, he wears a formal suit with a white ascot.

In Overdrive, on his walk with Erina when he first meets Will A. Zeppeli he wears a similar outfit to that of when he was young but it is brown and he wears a pink scarf.

In Overdrive, following his father's death, he wears some weird ass sweater over a brown long-sleeved shirt and wears a baseball cap backwards on his head.

In The Final Ripple! he wears a black tuxedo during his wedding with Erina.

In Who Will be the Judge? Jonathan appears in a flashback in the Part 3 art style.

In the JoJo's Bizarre Adventure: The Animation Season 1 official reveal, Jonathan wears an outfit similar to that which appears in the Volume 4 illustration.

History
TBA

I'll update this with info I didn't steal lawl

Age
In the first episode Jonathan is 12 years old, and then in the rest of Part 1 he is 20 years old.

Personality
Jonathan is described, mostly by himself and by other people, as a true gentleman. He never acts out of his own self-interest, which directly mirrors his arch rival Dio.

Hamon
Having been taught this ancient technique by Will A. Zeppeli, Jonathan harnesses the sun in order to defeat vampires and zombies such as Dio and his minions.

Some of his attacks:

 * Zoom Punch- Allows him to dislocate his arm and stretch it a few feet in order to hit an opponent.
 * Sunlight Yellow Overdrive- Sends Hamon through his body directly.

The Passion (non-canon)
In Part 3, using Jonathan's body, DIO is able to use a Hermit Purple-like Stand to spy on the Stardust Crusaders. This is intended to be Jonathan's latent Stand ability (named "The Passion" in the non-canon light novel Jorge Joestar,) which has the basic powers of Hermit Purple, those being clairvoyance and Hamon transmission.

Trivia

 * Jonathan's birthmark, which is a staple among members of the Joestar Family, is never shown in the manga, but in the anime, it is retconned into the Tarkus and Bruford fight.
 * The animators for the Part 4 OP "Great Days" intended for Jonathan to be added somewhere in the OP, but the writers stopped them, and included the rising sun at the beginning to be a representation of him.
 * It is a misconception that Jonathan was named after a restaurant that Araki went to called "Jonathan's" as he was actually called Jonathan Joestar because Araki wanted to have a protagonist who's name had alliteration, like the name Steven Spielberg.
