Well, from Naruto, Kakashi is a popular character to feature. His laid - back yet highly skilled nature can be a great contrast in a Yu - Gi - Oh GX crossover. He could teach the Yu - Gi - Oh GX characters some ninja tactics. In Yu - Gi - Oh GX, Bastion is often a favorite. His intellectual approach to dueling can be an interesting element when combined with the more action - based Naruto world. And among the Naruto characters, Sakura can also be a great addition to fanfiction. Her growth from a weakling to a strong kunoichi can be an inspiring sub - plot when interacting with Yu - Gi - Oh GX characters.
Jaden Yuki as a vampire is often popular. His energetic and fearless nature can take on a new dimension as a vampire. He could use his vampire powers to become an even more formidable duelist.
I like Syrus Truesdale. He's the underdog type of character. He struggles with self - confidence at first but as the series progresses, he grows and becomes a more capable duelist. His relationship with Jaden is also really endearing.
Jaden from Yu - Gi - Oh GX and Yusei from Yu - Gi - Oh 5DS are very likely to form an alliance. Jaden is known for his enthusiastic and adaptable dueling style, and he is always up for a challenge. Yusei, on the other hand, is a strategic and determined duelist. Their combination would be great as Jaden's out - of - the - box thinking could complement Yusei's well - planned strategies. They could face any enemy that comes their way with confidence.
Jaden Yuki is very memorable as the main protagonist. Also, Chazz Princeton with his complex personality.
One idea could be that Naruto somehow gets transported to the world of Yu - Gi - Oh GX. He could befriend Jaden and learn about Duel Monsters. Naruto's skills in combat and his determination could be applied in the Duel Monsters duels in an interesting way. For example, he might use his shadow clone technique to confuse his opponents during a duel.
The stories in Yu - Gi - Oh GX are not just about dueling. There are also tales of friendship and rivalry. Characters like Alexis Rhodes have their own storylines that involve their relationships with other students, as well as their pursuit of becoming better duelists. The story also explores the history and secrets of Duel Academy itself.
If Fairy Tail characters were in Yu - Gi - Oh GX fanfiction, they would likely change the dueling landscape. Their strong bonds of friendship would also play a role. Just like in Fairy Tail, they would support each other during duels. For instance, Happy could be a sidekick that gives Natsu some sort of boost during crucial moments in a duel. Their presence would add a more magical and adventurous feel to the Yu - Gi - Oh GX dueling world.
Maybe in this fanfiction, there's a new tournament that combines the skills from both Naruto's ninja world and Yu - Gi - Oh GX's dueling world. Characters from both universes participate. A character like Sasuke could also be part of the story. In the process of competing, some of the female characters from Yu - Gi - Oh GX are attracted to Sasuke's cool and mysterious demeanor, while Naruto forms his own group of admirers through his friendly and determined nature.
In Pokemon, Ash would be a likely candidate. He's the main character and is always up for new adventures. In Yu - Gi - Oh GX, Jaden is the obvious choice. He's brave and loves to duel. Imagine Ash and Jaden meeting. Ash could show Jaden how to catch Pokemon, and Jaden could introduce Ash to Duel Monsters. Another possibility is Misty from Pokemon. She could be interested in the magical aspects of Yu - Gi - Oh GX. And from Yu - Gi - Oh GX, Alexis could cross over. She might be intrigued by the cute Pokemon and how they are trained.
Ash from Pokemon and Yugi from Yu - Gi - Oh would be really interesting. Ash is a fearless and determined Pokemon trainer, while Yugi is a strategic and kind - hearted duelist. Their different personalities and skills would create a great dynamic. They could learn from each other, like Ash teaching Yugi about the bond between a trainer and a Pokemon, and Yugi showing Ash the intricacies of dueling.
