For Naruto, Tenten's discipline with her weapon training could inspire him to be more focused in his own training. He might start to practice new techniques with more precision.
If Naruto and Madara become friends, it could completely change the power balance. Their combined strength would be a deterrent to any potential invaders. On a more positive note, it could inspire a new generation of ninjas to look beyond past grudges. The younger ninjas would see that even the most bitter enemies can become friends. This could lead to a more unified ninja world where different clans and villages work together more closely. For example, the Uchiha clan might regain more trust within the Leaf village, and other villages might be more open to sharing resources and knowledge.
Their childhood friendship could lead to a stronger alliance in battles. When facing a common enemy, they would be able to anticipate each other's moves better. Tenten would know Naruto's fighting style and be able to back him up effectively, and Naruto would do the same for her. For example, in a war, Naruto could draw the enemy's attention while Tenten launches a surprise attack from the side using her array of weapons.
Their friendship could also lead to a different perspective on the Uchiha clan's situation. Itachi's actions were complex and his friendship with Naruto could have made Naruto more involved in the Uchiha clan's affairs. This might have led to a different solution to the conflict between the Uchiha clan and Konoha, preventing the massacre. In turn, this would have a huge impact on the political situation in the ninja world.
As childhood friends, they know each other's weaknesses and strengths well. This knowledge is crucial in their growth as shinobi. Ino can use her knowledge of Naruto's impulsive nature to keep him in check during joint missions. And Naruto, understanding Ino's sometimes over - confidence, can help her be more cautious. They learn from each other's mistakes and successes, and this continuous learning process is an important part of their development as shinobi.
Kushina's possessiveness could initially slow Naruto's growth. If she's too overprotective, he might not get the full experience of taking risks and learning from his mistakes. For instance, she might prevent him from going on dangerous missions early on.
Well, their friendship could inspire other characters. For instance, the younger ninja in the village might look up to them and see that friendships can cross different ninja styles. If Naruto, known for his unorthodox and powerful ninjutsu, can be friends with Tenten, who is a master of weaponry, it shows that different skills can complement each other.
In terms of their roles, Percy's role in protecting the mortal world and the demigods would be influenced by Artemis. Her skills in archery and tracking could be passed on to him in some way, making him an even more formidable defender. For Artemis, her friendship with Percy might make her more protective of his friends and family. This could expand her role from just being the goddess of the hunt to also being a guardian of those connected to Percy. Their friendship would blur the lines between the demigod and godly worlds a bit more, leading to new dynamics in the mythological realm.
Their presence could greatly enhance Naruto's growth. Just having the connection with his parents in the mindscape could give him a sense of belonging and purpose. His father was a highly skilled ninja, and he could pass on some of his combat knowledge and strategies. His mother, with her kind heart, could help Naruto develop his emotional intelligence, which is important for a ninja in dealing with allies and enemies alike.
Their friendship could change the way Sasuke's character develops. Instead of being so isolated and revenge - focused, with Naruto as a childhood friend, she might be more open to other paths. For example, she could be more willing to stay in the village and help improve it rather than seeking power elsewhere. Naruto, too, would have a different motivation. His drive to bring Sasuke back might be even stronger because of their long - standing friendship, and he would do everything to protect her from the darkness that threatens her.
Naruto's friends from Konoha would likely be very supportive. Kakashi might offer some wise words about the responsibilities of parenthood. Sakura would probably be there to help with any medical concerns Mirajane might have during the pregnancy. As for Mirajane's friends from Fairy Tail, they would be excited. Erza would be making sure Mirajane is well - protected and would probably train Naruto a bit to make sure he can defend his family. Gray might make some jokes to lighten the mood but also be ready to help out.
