One possible new power could be the power to absorb and use any chakra, regardless of its origin. This would make him extremely powerful as he could draw from the chakra of his enemies or even from natural sources like the sun or the earth. He could also gain the power of telepathy on a large scale, being able to communicate with anyone in the world or even across different dimensions. Additionally, he might obtain the power of instant teleportation to any place he desires, which would give him a huge advantage in battles and travels.
She might start by using her knowledge of Naruto's past. Since she is his mother, she knows things about his early life that no one else does. She could use these memories to create an emotional connection with him. Maybe she'll show up in his dreams first, like a hazy memory, and then gradually reveal herself in the real world.
One benefit is that it can expand his story in different ways. Fanfiction can explore alternate timelines or relationships that the original series might not have delved into deeply. For example, a fanfiction could explore what would happen if Naruto had a different mentor, which could give new insights into his character development.
There are several places where Naruto can get fanfiction. One of the most popular is FanFiction.net. It has a vast collection of Naruto - related fan - created stories. Another option is Archive of Our Own (AO3), which also has a large number of Naruto fanfictions with different themes and styles.

Well, often in Naruto fanfic, Naruto can get power from the Kyuubi when he manages to break through the mental barriers that were set in the original series. He might be able to communicate better with the Kyuubi and convince it to lend him more power. It could also be that some external force or event in the fanfic world allows him to access the Kyuubi's power in a new way, like a magical artifact or a new type of jutsu.
One reason could be betrayal. If someone he trusted, like a fellow ninja or an old acquaintance, turned out to be working for his enemies, that would surely make him pissed. It's a huge blow to his trust, which is a big part of his character.
Yes, he can. Fanfiction allows for a lot of creative liberties. Writers might imagine a scenario where Naruto somehow inherits or gains access to the Sharingan and then progresses to unlock Susanoo. For example, through some magical or chakra - related accident that fuses Uchiha genetics or power with Naruto's own. But it's important to note this is purely a fan - created concept and not part of the official Naruto lore.
