Anakin's new order might be a technological - Force hybrid. Given his skills as a pilot and his understanding of technology, the order could incorporate advanced technology in its training and operations. For example, they could use droids to assist in Force - related experiments or develop new weapons that are attuned to the Force, creating a new kind of warrior in the Star Wars universe.
The new order Anakin creates could be centered around family. Since Anakin's love for his family was a strong driving force in his life, the order might place great importance on the bonds between its members. It could also have a more inclusive approach, accepting those who were rejected by the old Jedi Order due to their backgrounds or past mistakes.
Younglings who were disillusioned with the old Jedi ways might be attracted to Anakin's new order. They could see it as a chance for a fresh start and a different approach to using the Force.
The new wand might have a core that is a combination of multiple magical elements. For example, a strand of a unicorn's hair combined with a shard of a powerful magical crystal. This would make the wand extremely versatile, able to channel different types of magic depending on how the wizard holds it and the incantation used.
Well, if Anakin stops Order 66 in the fanfic, it would mean that the Clone Troopers wouldn't turn on the Jedi. Anakin might have a change of heart after realizing the full implications of what Palpatine was asking him to do. He could then warn the Jedi Council. This would completely change the course of the Star Wars saga. The relationship between the Jedi, the clones, and the Republic would be very different, and there would be a whole new set of stories to tell about their future together.
Well, it could have the ability to manipulate time on a small scale. For example, the user could slow down time for a brief moment in battle, giving them an edge to dodge attacks or land precise strikes. This would be a really cool and unique ability compared to the existing bloodlines in the Naruto universe.
Well, in the fanfic, Anakin's skills would be a huge asset or a threat to the First Order. If he decides to join them, his combat abilities and knowledge of the Force could make the First Order even more powerful. However, if he realizes that they are on a wrong path, like the Sith - influenced path he once walked, he might use his skills to undermine the First Order from within. He could start by influencing the stormtroopers, showing them that there are other ways than blind obedience.
Well, he could either try to take over the First Order with his powerful Force abilities. Maybe he would see it as a new tool to gain more power and control in the galaxy.
The Jedi would be the most directly affected. They wouldn't be massacred, and their order could continue to thrive. Also, the clones would be affected as they wouldn't have to carry out the unjust order. And of course, Anakin himself would be on a different path, likely seen as a hero rather than a villain. Padmé might also be affected as she wouldn't have to witness Anakin's fall to the dark side.
It could be about Anakin struggling to connect with his new Padawan at first. Maybe the Padawan has a very different approach to the Force than Anakin does. For example, if the Padawan is more in tune with the peaceful aspects of the Force while Anakin is used to a more aggressive style. This difference could lead to some initial clashes between them. But as they go on adventures together, they gradually learn from each other and form a strong bond.
The Padawan could be a young alien from a species not often seen in the Jedi order. Maybe an amphibious species that has a different way of sensing the Force due to their unique physiology. This would make for an interesting dynamic as Anakin would have to adapt his teaching methods.
Perhaps they are ancient water spirits. These spirits could have the power to manipulate water in ways that normal ninjutsu can't. They could turn water into solid ice sculptures that can be used as shields or weapons. They might also be able to swim through the ground as if it was water, allowing Naruto to surprise his enemies from below.
