He could go on adventures to find rare medical herbs for Tsunade's research. Since he's her grandson, he might be more involved in her medical - ninjutsu related projects.
In this fanfiction, Naruto could embark on adventures to uncover the secrets of his family's past. With Tsunade's guidance, he might dig deeper into his family tree and find out about any hidden powers or legacies. This could lead him to ancient ninja ruins or face off against enemies who are also interested in his family's secrets. Along the way, he would grow stronger and more experienced as a ninja, while also strengthening his bond with Tsunade.
They could go on a mission to explore an ancient ruin filled with powerful but dangerous ninja artifacts. Naruto's curiosity would lead the way, while Tsunade's experience would keep them from making fatal mistakes. Maybe they encounter traps that only Naruto's unique skills can solve, like using his shadow clones to test the mechanisms.
They could go on medical ninjutsu adventures. Naruto might learn from Tsunade how to heal serious wounds quickly. For example, they could travel to battlefields and save countless lives together. Tsunade could also teach Naruto about chakra control in relation to medical jutsu, which would enhance his skills both in combat and in helping others.
They might have adventures like exploring ancient ruins. Naruto's enthusiasm and Tsunade's wisdom would be a great combination. They could discover long - lost jutsu or artifacts that could change the shinobi world. For example, they might find a scroll that contains a powerful sealing technique that was thought to be lost. Along the way, Naruto could also learn more about medical ninjutsu from Tsunade, which would enhance his skills as a well - rounded shinobi.
He could have adventures in Hera's realm. Maybe he has to face mythical creatures there to prove himself worthy of his new heritage. For example, he might encounter centaurs or minotaurs and have to use his ninja skills combined with any new powers from Hera to defeat them.
An adventure where they have to stop an evil force that is threatening both of their worlds. Naruto could bring his knowledge of sealing jutsu to prevent the evil from spreading, and Noire could use her leadership skills to gather allies.
One idea could be that Naruto inherits Tsunade's incredible strength and medical ninjutsu skills. Maybe in the fanfiction, he uses these skills in a new and unique way during battles, combining his own Rasengan - like techniques with Tsunade - style brute force punches. He could also use the medical ninjutsu to heal his friends more effectively, even in the heat of battle.
If Naruto is Esdeath's brother in fanfiction, they could embark on adventures across different dimensions. Since Naruto has experience with his own world and Esdeath with hers, they could explore new lands together. They might encounter strange creatures and powerful enemies. Along the way, they could learn from each other's fighting styles and abilities, Naruto teaching Esdeath about chakra and she teaching him about her own brand of combat techniques. And they could also be on a quest to reunite their fragmented family or uncover a long - hidden family secret that has the power to change their worlds.
One possible plotline could be Naruto growing up with a different set of skills influenced by Tsunade. Since Tsunade is known for her medical ninjutsu and super strength, Naruto might have an earlier inclination towards medical skills. He could be trained in a more balanced way between combat and healing. For example, in battles, he not only uses his regular jutsu but also heals his comrades instantly on the spot. Another aspect could be the political influence. Tsunade being an important figure in the village, Naruto might have a different standing in the village hierarchy from the start and face different kinds of challenges related to leadership and decision - making.
Naruto could potentially find some ancient ninja artifacts on the deserted island. These artifacts could hold great power or knowledge. He would then have to figure out how to use or protect them. There could also be some sort of mystery on the island, like a hidden cave with strange markings. Naruto, being the curious and adventurous type, would surely try to solve the mystery. This could lead to him learning new jutsu or uncovering secrets about the ninja world's past.
One possible way the storyline could develop is that Naruto would inherit some of Madara's powerful chakra and Sharingan - like abilities. Since Tsunade is known for her medical ninjutsu and superhuman strength, Naruto might also have a natural affinity for healing. This could lead to a new type of combat style for Naruto, where he combines his inherited skills with his own Rasengan - based techniques. He could use his Sharingan - like power to predict his opponents' moves and then counter with his Rasengan, while also being able to heal himself or his comrades in the heat of battle.
