Jo Kujo

Jo Kujo (空条 ジョー) is the hypothetical son of Jotaro Kujo and Shoko Nakagawa, created by Hirohiko Araki during an interview between Araki and Shoko in the $$ in 2006.

Appearance
Jo is a young boy with very short light hair, large ears, and thick eyebrows. He has three vertical dots on both cheeks under his eyes. He wears a t-shirt that says "JO" in the center, along with shorts and sneakers.

Personality
Jo's catchphrase is "Shut your mouth", which he always likes to say. He acts like he's and is prone to causing trouble by making random people get married with each other using his Stand. Him playing around eventually causes people to kill each other when they are forced into an unwanted marriage.

Stand
Jo can write the names of anybody into his Stand named Love Note, forcing them to get married regardless of their feelings. They will not be able to get divorced either.

Trivia

 * According to Araki, Jotaro can only be defeated by Jotaro himself or by the child of Jotaro and Shoko. Araki then changes his mind and says it's impossible to defeat Jotaro's Stand since he can stop time, so the child of Jotaro and Shoko would also have to be capable of manipulating time to stand a chance.
