This is a quick list of things I have changed in my FanFiction. More details are after the list.
1. Fillers.
2. Basic Chakra Nature.
3. Clans.
Extension & Explanation—
1. Fillers:
In my fictional world, every filler event and character is real and is part of the world. This means somethings are different; for example there exists a Dōjutsu that is legit a combination of Byakugan and Sharingan, surpassing even the sharingan (Excluding the Mangekyō and other Variants Of course).
2. Basic Chakra Natures:
In the entire Naruto series, canonically, NOBODY died from fire, not a single civillian let alone a Ninja!! The strongest wind user other than Naruto is Temari, whose strongest attack is a giant gust of wind!! And that's just the tip of the iceberg!
It fraustrates me to no end how every basic element that isn't lightning release is so weak that they are just for visual effects. Anyways, I have changed that, and now Fire burns, Water drowns, Wind Cuts, Earth crushes and lighting does what it did in the Canon.
3. Clans:
I think it goes without saying that every clan that wasn't directly related to Naruto got close to no exposure to the world in canon, and is generally thought to be weak, but that isn't actually the case, and I am simply letting you, the reader, know this beforehand as to not confuse you when I introduce clans in my fic.
In case you think, Clans are pretty weak then let me give you a quick rundown on what the few clans from Konoha can do:
Hyūga—Gentle Fist can cut through any Chakra Based Substance (Including Ninjutsu, because it's literally chakra in a physical form). Twin Lion fist, drains it's oponents Chakra.
Akimichi—These guys can do Titan Shifts, has power to use hundred times their regular strength for a short while and more.
Aburame—Dont even get me started on these guys, they can control things from microscopic bugs to bugs that can eat ten tails clones that absorb chakra on contact, they can track people down from countries away as long as one of their female bugs are stuck to their target. They were Danzo's favourite clan for his root recruitment, need I say more?
That's all, for this chapter.
