Jonathan Joestar (Original Universe)

Background

Jonathan Joestar has a minor role in the light novel JORGE JOESTAR. After Erina enters Dio 's coffin to escape the explosion of the ship on their honeymoon trip, she looks back wondering if she could somehow get Jonathan inside as well. However, Jonathan is using the last of his strength to hold Dio in his arms and Erina would not be able to move him in time. As the explosion hits, Dio escapes from Jonathan's grip and decapitates him before barely attaching his head to Jonathan's body.↗

While on his voyage with Erina, Dio would often use Jonathan's name to torture her, claiming things like Jonathan died because of Erina. A day later, Erina realizes that Dio must have brought Jonathan's head with him. After Dio throws Erina underwater while torturing her, she sees Jonathan's head bobbing up and down under the debris of the ship near the coffin. Erina swims to Jonathan's head assuming he would look like a zombie but his flesh miraculously hadn't decayed and he still looked alive.↗↗

When Dio gets his Stand, Jonathan's body also awakens a Stand named The Passion. It can see the futures of any of his descendants.↗↗

Eventually, Jonathan's head moves with Erina and George Joestar II to their basement in England.↗↗

Tonpetty tells George II that Jonathan was barely a man at all. He was a spoiled boy, weak-willed, not very smart, and prone to taking the easy way out. However, Jonathan always had a glimmer of courage.↗↗

In the final battle against Dio Brando, Jorge Joestar (Universe 37) A singularity from the 37th universe. Does not exist in the other universes. cuts off the supplementary head from the Saint's Corpse and places Jonathan's head on the stump. Jonathan's head fits on the body perfectly, as it was actually his body originally.↗

Erina wraps her shawl around Jonathan's waist so he wouldn't be naked. For a moment, Jorge could see Jonathan's Stand The Passion around his head. Jonathan revives and suddenly starts laughing, claiming that he is actually Dio since Dio had given him his blood after cutting off Jonathan's head on the boat. Everybody is shocked aside from Erina who could tell that he is joking. She scolds him by saying he should at least thank everyone for their help instead of joking like that.↗

Jonathan states that he couldn't remember anything after he passed out on the ship but he felt like he was watching a very long dream and what he just did was an inside joke between him and Dio, referencing what Joseph Joestar does in the future. When Dio was using The Passion to watch the futures of Jonathan's descendants, Jonathan had also been seeing them. Erina and Jonathan have a tearful reunion. Erina hesitates mentioning what happened to their son, George II, and Jonathan looks confused.↗↗
