Naruto's personality is all about believing in himself and his friends. When put into the Once Upon a Time world, he'd probably try to befriend everyone right away. This would be a shock to some of the more cautious characters like Regina. She's used to power plays and manipulation. Naruto's straightforward and friendly approach could either make her see a new way of doing things or she could see him as a threat to her control. And then there's Sakura. Her strong - willed nature could clash with the more submissive female characters in Once Upon a Time, but also inspire them to be more assertive.
Elsa's reserved and powerful nature would contrast with some of the more outgoing characters in Once Upon a Time. For example, she might initially be a bit intimidated by Regina's boldness, but then they could find common ground in their experiences of being misunderstood. Anna's bubbly and adventurous personality would likely make her fit right in with the more adventurous characters like Hook, and they could go on quests together.
Naruto is very optimistic and believes in the good in people. Devilman characters often face a much darker reality. So Naruto might clash with some Devilman characters who are more cynical. But at the same time, his positive attitude could start to influence them. For example, if he meets Akira, Naruto's cheerfulness might make Akira question his own dark view of the world.
In a Frozen - Once Upon a Time crossover, Elsa's cautious and self - isolating personality would be really interesting when combined with the world of Once Upon a Time. She might initially be wary of the new characters, but as she realizes they also face struggles, she could open up. Anna's eagerness to make friends and her loyalty would blend well with characters like Belle, who also values friendship. Kristoff would probably get along with the more down - to - earth characters. His no - nonsense attitude could be refreshing in the often - magical and complex world of Once Upon a Time.
HK 47's matter - of - fact and sometimes brutal nature would contrast sharply with Naruto's more emotional and idealistic self. However, they could blend in a way that Naruto could use HK 47's no - nonsense approach in battle. HK 47 might also be influenced by Naruto's loyalty to his friends and comrades, and start to show a form of loyalty in his own way. For instance, in a battle, HK 47 could protect Naruto's friends because he has come to respect Naruto's values.
Naruto is extremely determined and has a strong sense of justice. Peridot is goal - oriented in her own way, focused on her tasks related to the gems. Their personalities might blend in that they both strive towards achieving something. However, Naruto's more emotional and loud nature could be a bit much for Peridot at first. But over time, she could come to appreciate his passion and he could learn to value her calm and collected approach.
Naruto is known for his big heart and his desire to be recognized. Anna may have her own insecurities or goals. Their personalities would blend in that they both have a strong sense of justice. Naruto wants to protect his village and friends, and Anna might want to protect her own people or ideals. However, Naruto's loud and boisterous nature might initially annoy Anna who is used to a more subdued environment.
For example, Naruto's positive and determined personality would contrast with some of the more cynical Hetalia characters. Naruto is always looking for the good in people and striving for his goals no matter what. Some Hetalia characters, like Prussia, are more self - centered and prideful. But they could also blend as Naruto's enthusiasm might inspire Prussia to be a bit more altruistic. On the other hand, a character like Italy's laid - back nature could either annoy Naruto at first or make him relax more. Italy might also be in awe of Naruto's strength and determination.
Naruto is very outgoing and friendly, while Esdeath is cold and calculating. Their personalities would clash in many ways. Naruto would probably try to befriend Esdeath right away, but she might see his friendliness as a weakness. However, over time, Naruto's positive attitude could start to wear down Esdeath's cold exterior. His unwavering belief in people might make Esdeath question her own views on loyalty and power.
Naruto is very outgoing and hot - headed at times. Percy can also be impulsive. So, at first, they might clash because they both want to do things their own way. For example, when Naruto tries to teach Percy a new technique, Percy might be too eager and not listen properly. However, as they train together, they could start to blend. Naruto's determination could inspire Percy to be more focused, and Percy's loyalty to his friends could make Naruto appreciate the value of strong friendships more.
Naruto's naivete in some ways could be both a point of clash and blend with Harley Quinn. She might see his innocence as something to take advantage of at first, but as she gets to know him, it could remind her of a part of herself she lost. Her jaded view of the world could make Naruto more aware of the darker aspects of life outside of his ninja world. Overall, their personalities would create a complex dynamic that could be explored in many different ways in fanfiction.
