One big challenge for Benhypno in human form would be dealing with his memories and instincts from his alien self. He might have flashbacks or urges to act in an alien way when he's in a tense situation. For example, if he's in a fight, his first instinct might be to use his full alien powers, which he can't do without revealing himself. Also, he may face the challenge of making friends. Since he has a different background, he may find it hard to relate to normal human teenagers and their interests.
The plot could involve Benhypno trying to adapt to human society. Maybe he has to go to school and deal with normal teenage problems while hiding his true identity. He could struggle with making friends at first because of his unique background, but then gradually learn to fit in and use his powers in secret to help those in need.
One possibility could be that Benhypno in human form tries to blend into normal human society. He might struggle with understanding basic human emotions at first. For example, he could be confused by the concept of friendship and loyalty among humans. He might also have to deal with the fact that he has powers that he has to keep hidden from others, which could lead to some comical situations where he almost reveals himself accidentally.

For Naruto, he could develop more understanding of the darker side of the ninja world through his interactions with Tayuya.

Their relationship could also lead to a mutual growth in their spiritual powers as they support and learn from each other.
In a fanfiction, Sakura could develop her leadership skills. If she and Kushina are in a situation where they need to lead a group, Sakura could learn from Kushina's natural charisma.
