Isn't the multiple shadow doppelganger in Naruto forbidden? Why does everyone feel like everyone after Naruto? In fact, the setting of the multiple shadow doppelganger is not very friendly for most ordinary ninjas, and the threshold for use is relatively high, resulting in the fact that there are only a few characters in Naruto who can use the multi-shadow doppelganger, as explained below.
Kakashi's ability to use the Multiple Shadow Twins was entirely a loophole in Kishimoto's setting, otherwise Kakashi would not have been able to use the Multiple Shadow Twins in his frequently lacking blue image.
The reason why the Multiple Shadow Splitting Technique is listed as a forbidden art by the second generation of Naruto is that it takes the user to consume a lot of chakra to activate this skill, and if the total number of chakras is not high, or if the ninja with weak chakra control ability rushes to use this skill, there may be a very high risk (excessive consumption of chakra will lead to the death of the user).
However, kishimoto did not specify in detail the downline of chakra required for the multiple shadow splitting technique, which means that it is impossible to use this skill without stating that the amount of chakra does not reach much standard.
One of the reasons Kakashi was able to unleash the Multiple Shadow Twins after fighting with them was to exploit Kishimoto's loophole control over the restrictions on the use of the Multiple Shadow Splitters, otherwise, according to common sense, the amount of chakra consumed by Kakashi after a fierce battle would have been small, and it would be impossible to bear the consequences of using the Multiple Shadow Twins.
Of course, there is also a possibility that Kishimoto has ignored the problem of multiple shadow doppelganger settings in order to reflect Kakashi's strength, and has become accustomed to Kishimoto, who often digs pits in naruto.
In addition to Kakashi, another character who uses too many ghost doppelgangers is Tsunade's follower Mute, and the more interesting point is that Mute's value representing the total amount of chakra on the ninja formula book is the same as Kakashi's, so I personally speculate that the lower limit of the total amount of chakra required for the multiple shadow doppelganger is most likely 6.
Ninjas who do not reach this level will be life-threatening to use the Multiple Shadow Twins, and because the advantages of the Multiple Shadow Splitter techniques in the late Naruto period are not obvious, other powerful characters with exclusive skills will basically not easily use the Multiple Shadow Splitting Technique, because it costs too much chakra, and simply combining the multiple shadow body techniques to use it is not cost-effective for characters without the support of the tailed beast Chakra, and if you also have to use it with ninjutsu, the cost and price paid are too high.
Moreover, various powerful skills in the late Stage of Naruto are flying all over the sky, and the advantages of multiple shadow doppelgängers are basically eaten away by other skills in the later plot.
Hiroto has not used too many ghost doubles so far, not simply because of the lack of chakra, but because of the obvious difference from Naruto's previous period in terms of ability configuration.
As mentioned earlier, the so-called chakra limit of the Excessive Ghost Splitting Technique is flawed, and the criteria for judging the individual ability of ninjas through the values in the Ninja Formula Book have been abandoned. A new evaluation system is used in Hirohito (below)
The amount of chakra of the Bo people is 140, and the average amount of chakra of the ordinary people is 90, so can the Bo people use the multiple shadow splitting technique? At least in terms of the current content of boren biography, boren has only used the shadow double, for many reasons.
On the one hand, Bo Ren is not a nine-tailed human pillar force, and the chakra amount is not as good as his own father, but in fact, the lower limit for the use of multiple shadow doppelgangers is not high, otherwise Kakashi and Mute cannot use this technique, and Hirohito does not elaborate on what the lower limit of chakra use of multiple shadow doppelgangers after the use of the new ability evaluation system is.
Therefore, it is not very accurate to simply classify the reason why bo people cannot use the multiple shadow splitting technique to their own lack of chakra.
Personally, I think the reason why Hiroto does not use the multiple shadow doppelganger is because of the gap between the character setting and Naruto. In his early days, Naruto was a poor student in the ninja school, and his knowledge of ninjutsu theory was weak, so he had to rely on the Multi-Shadow Splitting Technique.
Hiroto's setting is magical, and his talent in ninjutsu far exceeds naruto's early naruto, so Hiroto's demand for multiple shadow splitting techniques is not high.
Since Hirohito uses ninjutsu far more than the early Naruto, coupled with the limitation of the total amount of chakra, Hirohito basically uses the shadow doppelganger + various types of ninjutsu to cope with the battle, and with the development of the Hirohito plot, Hirohito's other protagonist aura abilities are also reflected, such as net eyes, chi, etc. Are far more useful than multiple shadow doppelgangers.
Naturally, multiple shadow doppelgangers will not be used in various battles, of course, there is no direct evidence in the biography of Boren that Boren does not use multiple shadow doppelgangers, but due to the gap in settings, the multi-shadow doppelganger is not obvious to the improvement of the level of combat effectiveness of Boren.
Finally, to sum up, I personally think that there are not many characters in Naruto's use of multiple shadow doppelgangers, because on the one hand, this technique has relatively high requirements for chakra, on the other hand, as Naruto's combat strength continues to increase, the skill advantages of multi-shadow doppelgangers are greatly weakened, and there is no exclusive ability of various bloodline advantages that are easy to use.
