There could be a plot where Naruto absorbs the memories of all the villagers who once hated him. By doing so, he understands their fears and prejudices better. This could lead to him working towards a more united village in a new way. Another idea is that he absorbs the memories of different Kages throughout history. This gives him a unique perspective on leadership and how to handle different threats to the village. He could then use this knowledge to reform the shinobi world and make it a more peaceful place.
Well, it could make him more empathetic. If he absorbs memories of others' hardships, for example, he might be more understanding towards those who have suffered. He could also become wiser as he gains knowledge from the memories. Maybe he'll be more cautious in certain situations because he has seen the consequences in the absorbed memories.
One interesting plotline could be how Harry's character develops in a different way after absorbing the Hallows. Maybe he becomes more powerful than in the original series and uses this power to reshape the wizarding world. For example, he could use the combined power of the Hallows to end the discrimination between pure - bloods and half - bloods once and for all.
One potential risk is losing control. The Kyuubi's power is wild and Naruto might find it difficult to keep his sanity while using it.
One interesting plotline could be how Harry's character develops in a different way after absorbing the stone. Maybe he gains new magical abilities that are not in the original story, which could lead to unique adventures. For example, he might be able to communicate with magical creatures on a deeper level or have a stronger connection to the magic within Hogwarts itself.
One interesting aspect could be how Naruto's character might change with Sasuke's abilities absorbed. Maybe he becomes more brooding like Sasuke was at times, or perhaps he uses Sasuke's Sharingan - like skills in unique ways during battles.
One consequence could be an increase in Naruto's power. Since Dark Naruto represents his repressed negative emotions and power, absorbing it might give him a boost in strength and abilities. He could gain new jutsu or have enhanced versions of his existing ones.
One possible plotline could be that Naruto gets trapped in Minato's memories and has to find a way out. While inside, he relives important moments from Minato's life and gains new powers or knowledge.
Naruto could potentially gain the power of infinite chakra. Since the Ten - Tails is a source of massive chakra, absorbing it may give Naruto an unending supply, allowing him to use high - level jutsu continuously without getting tired.
He might gain the power of omnipotence. Just imagine, he could be able to control all the elements at will, not just the ones he already knew like fire, water, etc. He could also have the power to teleport anywhere in an instant, which would make him an even more formidable opponent in battles.
One interesting 'Naruto Memories Fanfiction' could be about Naruto's early memories of being alone in the village. It might explore how those experiences shaped his determination to be recognized. Another could focus on his memories of training with Iruka - that warm and guiding relationship.
