Naruto's ability to create a large number of shadow clones could be a major factor. In the Star Wars universe, the Jedi might see this as a form of over - powering or unethical power use. They could misunderstand his intentions and think he's trying to overpower them, leading to the feeling of betrayal. For example, if Naruto uses clones to scout a Jedi - held area, they might think he's spying on them for an enemy.
His chakra - based powers could be seen as a form of magic in Westeros. This would make him both feared and respected. For example, his ability to jump great heights and move at high speeds would make him a formidable opponent in battles. In the power struggle among the different houses, Naruto could easily tip the scales in favor of the side he chooses to support. He could also use his skills to protect the common people, which would earn him a lot of loyalty and further shift the power dynamics.
Naruto's ability to tap into the Nine - Tails' chakra would be a game - changer. In a betrayal scenario, if he's pushed to his limits, he could unleash the power of the Nine - Tails. This would make him extremely powerful, perhaps even on a level that the League of Legends champions have never faced before. He could use this power to fight against the League, causing massive destruction and upheaval in the League's world.
Perhaps in this fanfic, Naruto is forced to make a choice between his ninja values and the Jedi code. He might choose something that the Jedi don't agree with, like using his chakra in a way that goes against their light - side - only beliefs. The Jedi then shun him, making Naruto feel betrayed. He might then try to find his own path, separate from both the ninja world and the Jedi order.
Naruto's abilities would change the power dynamics. His superhuman strength and speed from being a ninja would make him a formidable ally to Bruce. For example, he could easily take on multiple thugs at once with his taijutsu skills.
Naruto's ability to use chakra could give Goku a new way to power up. Maybe Goku could learn to combine chakra with his ki, creating a whole new level of power. Also, Naruto's shadow clone jutsu could be used by Goku in his training, allowing him to fight multiple opponents at once and improve his skills faster.
Naruto would probably be extremely hurt. He has always considered Hinata a friend and perhaps more. Betrayal from her would be a huge blow to his trusting nature. He might initially be in denial, not wanting to believe that Hinata could do such a thing.
Naruto would be deeply hurt. He would probably feel a mix of anger and sadness. At first, he might try to reason with Tsunade, to find out why she betrayed him.
At first, Naruto would be shocked and confused. His world view would be shattered. But then, he would draw on his inner strength. He has overcome so many hardships before. He might feel a deep sadness, but also a sense of resolve. He would still believe in the power of love and friendship, and use that to face Kushina's betrayal. He could also use this experience to grow even stronger and more determined to prove himself and his beliefs.
His chakra control might be affected by the different magical energies in the DxD world. Maybe his chakra could interact with the devil or angelic powers in unexpected ways. For example, his Rasengan could gain new properties if combined with devilish power. His shadow clones might also be able to do things like sense magical auras, which they couldn't do in the Naruto world.
Naruto's chakra - based abilities could give Shanks' crew an edge. His speed and strength enhancements from chakra could be useful in battles. For example, his Sage Mode could make him a formidable fighter against strong enemies.
