Boruto's character development could be a complex journey. At first, he may feel overshadowed by his parents' fame and power. This could lead to him acting out or trying to prove himself in the wrong ways. However, as he experiences more of the ninja world and faces challenges, he starts to understand the true meaning of his parents' actions. He might develop a more empathetic side, seeing things from the perspective of others, especially those affected by Naruto and Sasuke's past actions. He also grows in terms of his combat skills, learning from both his father's brute force and Sasuke's finesse. His character arc could be about finding his own identity within the context of his parents' great reputations.
One idea could be Naruto taking Boruto on a special mission to an old, forgotten land. There, they discover a hidden power that was lost in the past. Boruto struggles to control it at first, but with Naruto's guidance, he learns to master it. This would show their bond and Naruto's experience guiding his son.
Well, a cool plotline could be Boruto having to deal with the combined enemies of his father and Sasuke. Enemies from Naruto's past might target Boruto to get revenge on Naruto, and at the same time, there could be remnants of Sasuke's old foes as well. Also, in the fanfic, it would be interesting to see how Boruto's training is different. Maybe he has both Naruto and Sasuke as his mentors, and they constantly bicker about the best training methods, which adds a bit of humor to the story.
Physically, Naruto can use his Rasengan or other powerful jutsus to fend off enemies attacking Boruto. His combat skills are top - notch, and he won't hesitate to engage in battle to keep Boruto safe.
Imagine a scenario where Boruto loses his memory. Naruto has to help him regain it. He shows Boruto all the important places in the village, tells him stories of their family. As Boruto slowly remembers, he realizes how much his father means to him and Naruto is relieved to have his son back. This would show the deep connection between them.
In the 'boruto kills naruto fanfiction', a motive could be a power struggle. Boruto might believe that Naruto's power is holding back the village's growth or his own potential. He could think that by eliminating Naruto, he can bring about a new era of power in the Hidden Leaf. Also, it could be out of desperation. If Boruto is in a situation where he believes that killing Naruto is the only way to save someone he loves, like his mother or a friend, he might take such a drastic step.
Maybe it's the high expectations that Naruto has for Boruto. Naruto is a hero, and he might unknowingly put a lot of pressure on Boruto to follow in his footsteps. Boruto could be scared of not being able to meet those expectations.
They could start by having an honest conversation. Naruto could sit down with Boruto and just listen to his fears without judgment. This would be a first step in building a better relationship.
