Well, Naruto is a very empathetic character. He might try to find the good in the Lich King, or at least the reason behind his actions. He could offer the Lich King a chance at redemption, using his own story of how he overcame his inner darkness. On the other hand, the Lich King might see Naruto as a powerful new minion or a threat to his rule.
One idea could be that Naruto is somehow transported to the world of the Lich King. He might use his ninja skills, like shadow clones, to fight against the undead minions of the Lich King. His chakra could be seen as a strange and new form of energy in that world.
Naruto would probably be very excited to meet Samus. He would be constantly asking her about her suit and weapons. Samus might be a bit more reserved at first, but would soon warm up to Naruto's enthusiasm. They could exchange fighting techniques, with Naruto showing Samus some of his ninja moves and Samus demonstrating how to use her arm cannon effectively.
Naruto would probably be very curious about Jinx. He'd be constantly asking her questions about her world and her gadgets. Jinx, on the other hand, might find Naruto's enthusiasm annoying at first. But she'd also be interested in his ninja powers. Eventually, they'd start to bond over their shared sense of adventure and a bit of a rebellious streak.
Naruto might be initially confused by Cheshire's strange appearance and abilities. But being the friendly and curious person he is, he would soon start to ask questions. Cheshire, on the other hand, would probably be amused by Naruto's energy and determination. It could play tricks on Naruto at first, but as they get to know each other, they would form a bond.
Naruto might also have some cultural misunderstandings at first. For instance, he might not understand the concept of queuing and accidentally cut in line, causing some confusion. But as he spends more time in England, he would learn the local customs and adapt, making friends along the way.
Sasuke might initially be suspicious of King Kong. He would see it as a potential threat to the ninja world. Naruto, on the other hand, would be more open - minded. He would probably try to make friends with King Kong right away. Sakura might be a bit scared at first but then be impressed by King Kong's strength and want to study it in a medical - ninja way to see how such a large creature functions.
Naruto would probably be very enthusiastic and curious about Amanda Holliday. He'd be constantly asking her questions about her world and all the cool gadgets she has.

They'd likely bond over their shared sense of adventure and their determination to face any challenges that come their way.
Hera might be very protective of little Naruto. Given her nature as a goddess in her own mythology, she would see Naruto's vulnerability and want to shield him. For example, when Naruto is bullied, Hera could use her powers to scare off the bullies without Naruto even knowing.
Naruto would likely be his energetic and friendly self. He would probably greet Roku Shimai with a big smile and start asking her all kinds of questions. Roku Shimai might be a bit more reserved at first, but Naruto's enthusiasm would gradually draw her out.
