Kakashi is important too. As an experienced ninja and a mentor figure, he can provide strategic advice and also jump into the fray when needed. His knowledge of different jutsu and his understanding of the enemy can be a great asset in the fanfic's Fourth War.
Obviously Naruto is one of the most important. His strength and his ability to inspire others are crucial in the Fourth War setting. He's the one who can turn the tides with his positive attitude and powerful jutsu.
Obviously, Naruto himself is the most important. But his friends like Sasuke would also play a significant role. Sasuke could be Naruto's right - hand man, helping him with security and intelligence matters in the village.
Obviously Naruto would still be one of the main characters. He played a huge part in the Fourth War and his influence would still be felt strongly in the post - war world. Sasuke would also be a main character as he was a key figure in the war as well. And Sakura, who has grown into a strong kunoichi, would also be important in the story.
Well, Naruto and Sasuke are the obvious ones. They are the main characters in the original series and their power levels and relationships are always a big part of any fanfic. But in Naruto God Tree fanfic, characters like Hagoromo and Hamura, the sons of Kaguya, could also be very important. They have a primordial connection to the God Tree as their mother was closely associated with it. Also, Orochimaru could be a significant character. His thirst for knowledge and his ability to experiment could lead him to be interested in the God Tree, and he could either be a villain or an unexpected ally in fanfics.
Naruto would likely still be one of the most important characters. His role as a main protagonist in the original Naruto series means he'd probably play a crucial part in any fanfic with a 'destined to happen' theme, whether it's about fulfilling a new prophecy or saving the world in a different way.
Naruto is definitely one of the most popular. Since he's the hero of the war, many fanfics will focus on his post - war life, like his family life with Hinata and his role as Hokage. Sasuke is also very popular. His complex character and his journey of redemption in the post - war world are often explored. Sakura is another, especially her growth as a medic - ninja and her relationships post - war.
Well, Gideon Jura is an important character. He is known for his courage and combat skills. He often takes on the role of a front - line fighter. Another important character is Teferi, who has the power over time. His ability to manipulate time is a major factor in the overall strategy of the war and the events that unfold in the novels.
Odysseus is very important. He is known for his cleverness and guile. He comes up with the idea of the Trojan Horse. Agamemnon, the leader of the Greek forces, is another significant character. He has power and authority over the Greek army. And Ajax, a great Greek warrior, is also among the important ones.
Ichigo is definitely one of the most important. His power and his role as a bridge between different spiritual worlds make him central. Also, Yhwach as the main antagonist of the Thousand - Year Blood War in the original series would likely be important in the fanfic too. And Uryu, being a Quincy, would play a crucial part as his story is deeply intertwined with the Quincy - Soul Reaper conflict.
Zatanna also plays a significant role. Her powerful magic skills are essential for combating the dark forces of Apokolips. She can perform spells that can turn the tide of battle, whether it's for defense or offense.
Other important characters could be the enemies they faced during that era. For instance, the ninjas from other villages they fought against in the wars. These enemies could help showcase the Sannin's combat abilities and strategic thinking. Also, some of their comrades from Konoha, like Kakashi's father Sakumo Hatake, could be included to add more depth to the story.
