One idea could be to have characters from 'Game of Thrones' possess Stands like in 'Jojo's Bizarre Adventure'. For example, Jon Snow could have a Stand that gives him enhanced combat skills in the cold, similar to his natural ability in the North. Another could be a story where Daenerys' dragons are somehow related to Stands, perhaps her dragons are manifestations of a powerful Stand she unknowingly has.
It could be Jon Snow. If he has a Stand in the fanfiction, combined with his already proven leadership skills and combat abilities, he would be a force to be reckoned with. His ability to come back from the dead might also be related to his Stand powers in some way, making him even more formidable.
Jojo Siwa's life story is quite remarkable. She became famous for her appearances on reality shows like 'Dance Moms'. From there, she branched out into her own brand. She has her own line of merchandise, from toys to clothing. Her music is also a big part of her story. It's upbeat and often features positive messages, which has endeared her to her fans. She has also been an inspiration for young girls, showing that with hard work and a unique personality, one can achieve great things in the entertainment world.
One main highlight is her rise to fame through dancing. Her skills made her stand out. Another is her merchandise success. Her bows and other products are very popular.
There's no way to really tell if it's common specifically for someone named Jojo. However, in general, reading fanfiction is a popular activity among fans of many different franchises. The Jojo series has a large and dedicated fan base, so it's likely that there are fans named Jojo who partake in reading fanfiction, but we can't say for sure how common it is without more data.
Perhaps this Jojo is interested in exploring different interpretations and stories within the Jojo universe that fans have come up with. Fanfiction often takes the existing characters, settings, etc. from the original Jojo series and creates new and unique storylines. So, this Jojo might be a big fan of the series and wants to see what other fans have imagined.
It could be really wild. Imagine the Stand users from JoJo in the political intrigue of Westeros. Maybe Dio could be a power - hungry lord, using his time - stopping abilities to plot against other houses. And the Starks could have their own hidden Stand powers that help them in the battles for the Iron Throne.
The plot could start with a portal opening between the two worlds. A JoJo character accidentally stumbles into Westeros. Then, they get involved in the power struggles. Maybe they side with a particular house and help them in their battles. For example, if Josuke Higashikata enters, he could use Crazy Diamond to heal the wounded soldiers of the house he supports.
