One possible plot could be that the twin brother has a very different personality from Naruto. Maybe he is more reserved and studious while Naruto is brash and energetic. The twin could secretly be training in a different type of jutsu, perhaps more focused on genjutsu while Naruto is into rasengan and other offensive ninjutsu. Their relationship might start off rocky as they compete for recognition in the village, but eventually they come to realize they are stronger together and support each other in battles against powerful enemies.
The twin brother could have been born with a special power that the village elders feared. So they sent him away secretly. Naruto, oblivious to this, continues his life. However, as Naruto faces more and more challenges, the twin brother, who has been living in isolation and honing his skills, decides to return to the village. He initially disguises himself to observe Naruto. Eventually, he reveals himself and together they face a great threat to the village. They combine their unique abilities, Naruto's strength and determination with the twin's special power, to save the village.
