I think Bran Stark could be very interesting too. As the Three - Eyed Raven, he has vast knowledge and powers. In a future fanfic, he could use his powers to foresee and prevent new disasters or to guide the future of Westeros in a more positive direction. However, his new powers might also make him a target for those who fear his influence.
Definitely Tyrion Lannister. In a crossover with 'The Simpsons', he could bring his sharp wit and political acumen to Springfield. He'd probably outwit Mr. Burns in no time. His complex personality and ability to adapt would make for a very engaging character in such a crossover fanfiction.
Definitely Jaime Lannister. His character had a lot of development in the original series. If reincarnated, he could either redeem himself even further or take a completely different path. He might try to make amends for his past actions by becoming a true knight, or he could turn against his family if he realizes the toxicity of their ways. His reincarnation would bring a whole new set of possibilities to the story.
I think Tyrion would still be really interesting. He's so clever and adaptable. In a modern setting, he could be a brilliant strategist in business or politics, using his wits to outmaneuver his opponents just like he did in the show.
Daenerys Targaryen would also be a top candidate. Her quest for the Iron Throne and her connection with her dragons. When she meets the demigods, she might see them as either threats or potential allies. Her experience with magic and her strong will would make for some intense interactions with the Percy Jackson characters, especially when it comes to issues of power and leadership.
Jon Snow would be an interesting character in a 'Game of Thrones' and 'Harry Potter' crossover. He has a strong sense of duty and honor, similar to some of the characters in Harry Potter. He could be introduced to the concept of magic and might be skeptical at first. But as he sees the power of magic, he could use it to better protect the North. He could also learn from the wizards about different ways of leadership. And his relationship with the direwolves could be explored in new ways, especially if there was some sort of magical connection between them and the magical creatures in Harry Potter's world.
Guts would be a very interesting character to crossover. His tough - as - nails attitude and his massive sword would make him stand out in the world of GoT. He has a lot of combat experience and a dark past, which could make for some great interactions with the morally ambiguous characters in GoT.
Well, it could also be argued that Daenerys Targaryen might be very powerful in such a fanfic. She has her dragons, which are extremely powerful weapons. If she were to enter Narnia, she could potentially use her dragons to gain a stronghold. However, she would still be no match for Aslan in terms of pure power and divine essence.
Daenerys Targaryen is quite popular. Her character had a complex arc in the series, especially in the final season, and many fanfic writers like to explore different paths for her. They might write about what could have happened if she had made different choices during her conquest of Westeros.
Definitely Jon Snow. His mysterious parentage and his role as a hero make him a popular choice. Daenerys Targaryen is also very popular. Her journey from an exiled princess to a powerful queen gives a lot of material for fanfic writers. Arya Stark is another favorite. Her badass skills and her quest for revenge are really interesting to explore in fanfic.
Iruka sensei could be a great character. He could use coffee as a way to bond with Naruto and the other students. In the fanfic, he could introduce them to different types of coffee from around the world (in the Naruto universe), and through these coffee - related lessons, teach them important life lessons as well.
