How do you do a remake of the Naruto anime and manga to make it more in line with the general trend of science fantasy, science fiction, urban fantasy, dungeon crawler, cyberpunk, dark and high fantasy, Bancho and sukeban, action-packed, dark, edgy and gore filled style of seinen and shonen that was popular in both anime and manga until around 2005-2012, when the moe and ecchi trend took over in anime and manga, with Uzumaki Naruto being more true to life to this particular trend of shonen and seinen protagonists and being a more realistic, true to life character in general instead of being a happy go lucky delusional, self-righteous, clueless and selfish idiot with a messiah complex who consistently seeks acknowledgment from the people around him like in canon Naruto.

Naruto in this remake doesn't seek acknowledgement from the people around him, wish to be Hokage, or have the save everyone mentality of his canon self. 

 The World of Naruto is a post-apocalyptic Earth after WW3 and a subsequent nuclear holocaust in which Ōtsutsuki Kaguya was only ever able to defeat the Ten Tails [the Ten Tailed Wolf from Naruto fanon, not the mutated Shinju that was the canon Ten Tails, even though the Shinju still exists in the scenario] and along with her sons, Hamura and Hagoromo, better known as the Sage of Six Paths from Naruto  spread chakra across the globe hundreds, or even thousands of years before the events of the Naruto series in this scenario, due to the apocalypse in this scenario.

Chakra-using fake shinobi still use jutsu like in canon Naruto but use hand to hand combat, knife play and guns in battle like real-life soldiers and SWAT groups. 

Speaking of guns, tanks, aircraft and naval powers, these still exist and are important, Chakra-using fake shinobi just make war easier. 

 Uchiha Madara is the reincarnation of Hagoromo's youngest son, Ōtsutsuki Asura and Senju Hashirama is the reincarnation of Asura's older brother and rival, Ōtsutsuki Indra in this scenario.

 Asura's desire for peace and unity drives Madara's actions unconsciously and Indra's desire for control drives Hashirama's actions unconsciously.

Black Zetsu's schemes to revive Kaguya are more coherent and thought out. 


 In the hidden villages of chakra-using fake shinobi which make up the main backstory, with Konoha being Sacramento and the Hidden Rain Village being NYC, the Kages of these respective villages are simply Mayor's with too many powers and the combined status of a warlord and have to collaborate with the overarching government [Konoha's ANBU is officially under Sacramento SWAT]. 

The massive Kaiju battles and wuxia-style battles seen in later Shippuden especially during the Fourth Shinobi  World War don't exist here, shinobi are like their historical counterparts in feudal Japan under the shogunates and are spread out across SWAT and special forces, there are no child soldiers officially unlike in canon Naruto, talented children are secretly selected from orphanages and/or kidnapped to serve as Chakra-using fake shinobi by Chakra-using fake shinobi, but of course the masses don't know.


People capable of Kaiju battles and wuxia feats exist here, but they're not ninjas in this story, just legends and myths to even the regular Chakra-using fake shinobi. 


Naruto is Asura's latest reincarnation after Madara and Sasuke is Indra's latest reincarnation after Hashirama.
