Sakura could be really interesting. She might be confused at first by Menma's presence, thinking he's some kind of impostor Naruto. But as she gets to know him, she could see his unique qualities and might even develop a friendly rivalry with him. Another interesting character could be Kakashi. He would be observing Naruto and Menma's interactions closely, maybe even giving them some special training to help them work together better.
Well, one possible plot could be that Naruto and Menma initially clash due to their different personalities. Naruto is brash and determined, while Menma might be more laid - back. But as the story progresses, they discover they have a common goal, like protecting their village from a new threat. They then combine their skills, Naruto's Rasengan and Menma's unique jutsu, to defeat the enemy and in the process, become good friends.
One common theme is self - discovery. When Natsu meets another version of himself, he often learns new things about his own capabilities and personality. Another theme is cooperation. Since they are essentially the same person, they have to learn to work together despite their initial differences.
One common theme is self - discovery. Peter often has to re - evaluate who he is when he sees different versions of himself in alternate dimensions. For example, he might see a version of himself that is more ruthless or more vulnerable, which makes him think about his own values.
In these fanfictions, Naruto's character is often based on his canonical self, which is full of energy and a bit of a goofball at times. Menma, on the other hand, may be a bit more mysterious or have a different backstory that shapes his character. But they can both have a strong sense of justice. Naruto has always fought for what he believes is right in the main series, and Menma can be written to have a similar moral compass in fanfiction. They may also both experience growth throughout the story, learning from their mistakes and becoming better ninja.

There's a great piece of 'natsu meets natsu dimension travel fanfiction' where Natsu travels to a parallel dimension and meets another version of himself.

It's really exciting to read how they interact and grow together.
In fanfiction, Naruto might be more openly affectionate compared to the original series. He could be quicker to show his feelings for Menma. Menma, on the other hand, might be more reserved in some fanfictions, adding an interesting dynamic as Naruto tries to break through his shell.
