Well, the plot could involve Naruto coming across a powerful being from the Dragon Ball universe who decides to teach him the Kamehameha. Naruto, being the eager learner he is, starts practicing it. He might struggle at first because the chakra control required for the Kamehameha is different from his normal jutsu. But as he trains more, he gradually gets better. He could then use this new skill in a big battle against a common enemy, surprising his friends and foes alike.
In this fanfiction, perhaps Naruto is sent to a different dimension where he meets Master Roshi. Roshi sees Naruto's potential and decides to train him in the Kamehameha. Naruto combines his own ninja skills with the Kamehameha. For example, he might use his shadow clone jutsu to create multiple clones that all perform the Kamehameha at once, creating a super - powerful attack. This would make him even more of a formidable opponent in the Naruto universe.
The plot could start with Naruto finding a strange scroll that contains the secrets of the Kamehameha. He tries to decipher it with the help of his friends like Sasuke and Sakura. Sasuke might be skeptical at first, but as Naruto starts to show progress, he becomes more interested. Naruto then has to train his body to withstand the power of the Kamehameha. He might do this by doing intense physical training in addition to his normal ninja training. Eventually, he masters the Kamehameha and uses it to protect his village from a new and powerful threat.
