Flash could also be a likely candidate. He's quick - tempered at times. If he sees Naruto doing something that he thinks is wrong or dangerous, like using his ninjutsu in a populated area, he might immediately confront Naruto and this could spark a conflict. Also, Naruto's headstrong nature means he won't back down easily if he feels he's being wrongly accused, so it could escalate quickly.
Batman and Superman are likely candidates. Their different ideologies often put them at odds. Batman is more of a cautious and sometimes cynical character, while Superman is an idealist. In a fanfiction, Batman might suspect Superman of becoming too powerful and a potential threat to humanity, which could start a conflict that divides the Justice League.
Well, I think Green Lantern and Rock Lee would be an interesting pair. Green Lantern's power of creating constructs with his ring could be used in creative ways along with Rock Lee's taijutsu. Also, Wonder Woman and Hinata could be paired. Wonder Woman's combat skills and Hinata's Byakugan - enhanced fighting style would make for a great combination. And Flash and Kiba with his dog Akamaru could be a fun pair, with Flash's speed and Kiba's speed - based ninja techniques.
Another possibility is Flash and Naruto. Flash, with his super - speed, would be one of the first to reach Naruto if he suddenly appears in the DC world. Flash's friendly and curious nature would lead him to start a conversation with Naruto right away. Naruto would be amazed by Flash's speed and might try to compete with him in some way, which could be the start of their interaction.
Naruto and Superman would be a likely pair. Naruto has his unwavering willpower and his powerful ninjutsu skills, while Superman has his super strength, flight, and various other powers. They could both inspire each other. Superman could be amazed by Naruto's ability to keep fighting no matter the odds, and Naruto could look up to Superman as a powerful hero. Another good combination could be Batman and Kakashi. Batman is the world's greatest detective, and Kakashi is a highly intelligent and skilled ninja. They could share strategies and techniques in dealing with threats.
Hermione Granger could have an interesting interaction with Batman. Both are highly intelligent and strategic. Hermione could share her knowledge of magic and ancient texts, while Batman could teach her some detective skills and how to use technology in combat situations.
Definitely Superman. He has the strength and the moral compass to try and understand the Hulk. He can also withstand the Hulk's attacks to a certain extent, so he could be the first to approach the Hulk and attempt to form an alliance. He might see the good in the Hulk, similar to how he sees the potential for good in Lex Luthor at times.
It could be Cyborg. Since Cyborg is part machine, he and Iron Man could bond over their technological aspects. They could share knowledge about their cybernetic enhancements and work together to develop new tech or combat strategies against a common enemy.
Captain America and Wonder Woman could potentially be rivals. Captain America has his strong sense of patriotism and old - fashioned values from the 1940s, while Wonder Woman comes from an ancient, mythical island with her own set of values. They might clash over different ideas of leadership and how to handle certain situations, like when to use force or diplomacy.
Tim Drake from the Batfamily might be likely. He's highly intelligent and sometimes over - thinks situations. If he discovers some unusual activity related to Young Justice that he misinterprets, he could be the one to start the ball rolling on a conflict. For example, if he sees some new Young Justice members using untested tech that he thinks could be dangerous, he might take preemptive action against them.
Definitely Superman and Captain America. Superman is a near - all - powerful alien with a strong moral compass, while Captain America is a super - soldier representing the best of humanity. They could have some great conversations about power, responsibility, and what it means to be a hero. Their leadership styles are also different, which could lead to some interesting clashes and compromises within the combined team.
