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.
Alexis Rhodes from Yu - Gi - Oh GX and Akiza Izinski from Yu - Gi - Oh 5DS could form an alliance. Alexis is a skilled duelist with a kind heart, and Akiza has her own unique psychic powers in dueling. They could bond over their shared experiences as female duelists in their respective worlds. Their alliance could bring a different dynamic to the story, with Alexis' more traditional dueling skills and Akiza's special powers working together to overcome challenges, especially those related to enemies who underestimate them because of their gender.
A cool plot could be that there is a mysterious tournament that somehow bridges the two worlds. Duelists from Yu - Gi - Oh GX and Yu - Gi - Oh 5DS are invited to participate. However, it's not a normal tournament as there are strange rules and hidden agendas. The GX characters, like Jaden, bring their fun - loving and sometimes unpredictable dueling styles, while the 5DS characters, such as Yusei, bring their more strategic and high - speed dueling approaches. As the tournament progresses, they start to uncover the truth behind it and have to work together to stop those who are misusing the tournament for evil purposes.
I think Yugi and Captain America would be likely to form an alliance first. Yugi is a kind - hearted and brave character, and Captain America is all about justice and leadership. They would recognize these qualities in each other quickly and start to work together to face the challenges in the crossover situation.
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.
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.
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.
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.
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.
When writing the plot, create a conflict that can only be resolved through the combined efforts of the crossover characters. For instance, a new powerful enemy that can only be defeated by the unique skills of both 5ds and the other series' duelists. Also, pay attention to the dueling mechanics. Keep them true to the Yu Gi Oh spirit but add some new twists that come from the crossover. Write in a way that both new and old fans of Yu Gi Oh can enjoy the story.
I really like '5ds and GX: A Crossover of Worlds'. In this fanfiction, the settings of 5ds and GX collide. The characters have to adapt to the new rules and environments. For example, Jaden from GX has to learn about the Synchro Summoning of 5ds. It's full of action - packed duels and some great character interactions that make it a must - read for fans.
In a Yu - Gi - Oh GX crossover fanfic, I think Aster Phoenix would be a great addition. His cool and confident demeanor and his strong connection to his cards could add a lot of depth. Also, the Ojama Trio could be included for some comical relief. They could get into all sorts of wacky situations in the crossover world. Additionally, Atticus Rhodes. His laid - back attitude and his relationship with Alexis could be explored further in a crossover, especially if there are elements of romance or family drama involved in the new world.
