Naruto's energetic and enthusiastic personality would make him a fan - favorite in the WWE. He'd be constantly hyping up the crowd, just like he does with his friends in the ninja world. His bright orange jumpsuit would also be a very distinct look in the WWE arena.
Well, Naruto could bring his ninja skills to the WWE ring. He might use his Shadow Clone Jutsu to confuse his opponents. For example, when facing a big wrestler like The Undertaker, he could create multiple clones and surround him, making it hard for The Undertaker to figure out which one is the real Naruto. Then he could quickly strike with a Rasengan - a powerful spinning energy attack in his hands - when the opponent is distracted.
Naruto's ability to create shadow clones would be a great advantage in the WWE ring. He could use them to surround his opponents or perform multiple attacks at once. Sasuke's Chidori could be like a super - powered spear move. Rock Lee's taijutsu skills would make him a formidable wrestler with his fast kicks and punches. Hinata's Gentle Fist style could be used for precise strikes against opponents.
He would probably keep his core values like friendship and determination, but would have to adjust to the different technology and combat styles in Red vs Blue.
His ninja skills would bring a whole new level of excitement. For example, his Rasengan could be adapted into a powerful finishing move. He might create a 'WWE Rasengan' that would stun his opponents. Also, his ability to jump high and far could make for some amazing aerial maneuvers in the ring.
He might be adapted as a sort of foreign nobleman with strange powers. His Iron Man suit could be seen as a magical armor. He'd bring his sense of humor and quick - wittedness to the courtly intrigues of Westeros.
Peter Parker's character would likely retain his sense of justice. In the Hunger Games fanfic, he'd be the underdog using his powers for good. For example, he'd try to protect the weaker tributes.
Naruto would likely become more studious. Instead of just relying on his natural energy and willpower, he'd have to spend time in labs and studying books. His impulsiveness might decrease as he learns the importance of precision in scientific work.
His view of the world would expand greatly. If Naruto is a Xenophage in this fanfic, he would be exposed to different types of entities and powers that are not native to his world. This would make him more open - minded and curious. He would start to question the nature of his own world and the existence of other dimensions. His character would develop from a simple - minded, if brave, ninja to a more complex and philosophical figure, constantly seeking to understand the greater mysteries of the universe while still maintaining his core values of protecting his friends and village.
Naruto's character could develop a sense of pride that he didn't have before. This Super Saiyan 3 form is something extraordinary, and he might start to show it off a bit. But at the same time, he would also have to learn humility. If he becomes too arrogant, his friends might distance themselves from him. So he would be in a constant struggle between showing off his power and being the humble ninja he was raised to be. Also, his leadership skills might improve as he now has a power that others look up to, and he would need to lead by example when it comes to using this power responsibly.
Naruto might become more cautious. Dealing with the 12 - tails, which is likely extremely powerful, would force him to think before acting. He can't just rush in like he sometimes does.
