What if to rate Matkai's strongest skill Night Kai? Objectively speaking, although this move has a prominent damage effect, the defects are also obvious, so this move is not too good for individuals from the perspective of combat efficiency, which is explained below.
In the early battle system of Naruto, Matkai does not need to open eight doors to suppress most opponents, so the existence of Night Kai is relatively chicken.
In Naruto's combat power system, ninjutsu occupies the majority, which is the part that Kishimoto focuses on portraying, and the status of physical arts is not high in Naruto, most of the conventional ninjutsu, the output effect of magic is better than the conventional physical arts used by ninjas, in order to maintain the overall balance of the three subdivisions of ninjutsu, physical arts, and magic as much as possible.
Kishimoto introduced the so-called Eight Doors Of Armor concept to rely on special means to greatly enhance the ninja's physical output effect, of course, the cost is also very high, and the character who can master the Eight Doors Armor needs to undergo rigorous training to be able to use the Eight Doors Armor. Purely from the perspective of the ultimate Upanishads of the Eight Doors, the Upanishads, it had little effect in the early stages of Naruto.
The reason is that the various bloodline boundaries in the early stages of Naruto, the bloodline advantage and other special abilities are not so obvious compared to conventional attack skills, and if you want to deal with these threats, Matkai does not need to use night kai, and opening the first few doors can achieve the suppression effect.
For example, against the ghost fish of the Xiao Organization, Matkai can open the sixth door to have the effect of suppressing the opponent. Night Kai has no place to play at all, and if you force the use of Night Kai in the face of enemies of low rank, it is completely a cattle knife to kill chickens, and the price paid far exceeds the benefits.
At that time, the stage that the Eight Gates of The Dragon Armor had just introduced should be the first Naka Ninja Exam, and it happened to encounter the plan of the Great Snake Maru and the Sand Ninja to invade The Muye Village, why didn't Matkai use the Night Kai to save the Kiba Village? The reason is not complicated the use of night kai is too expensive.
And when encountering some opponents with special abilities, even if the damage effect of the night Kai is amazing, it is difficult to guarantee that the opponent will be killed 100%, but it will cause the user to die quickly.
Although various special ability holders appeared in the middle and late stages of Naruto, Night Kai's advantage in damage effect was getting less and less.
Many people ridiculed naruto's later content as basically the immortal fight, which showed that its combat power level increased abnormally fast, and at this stage, it was difficult for Ye Kai to fully exert its super attack damage effect.
If you compare the cost performance of skills, it is difficult for Night Kai to become the top of the pyramid in Naruto, and as there are more and more characters with special abilities later in the story, Night Kai's suppression effect gradually weakens.
Of course, it is undeniable that if you simply compare the destructive effects, Night Kai is indeed one of the best in the Naruto type. However, the cost of using skills is too high, and Matkai can only choose to use Night Kai as a killer in the stage of desperate struggle.
If naruto hadn't rescued Matkai once in the final stage, the strongest user of the Eight Doors Of Armor might have immediately withdrawn from the stage of history, because the cost of using its skills was too high, and the result was that it was difficult to suppress opponents above the sixth level, such as the existence of Yuki, which could not be destroyed by the conventional means of the Naruto World, and the use value of Night Kai was very low. Even for opponents below the six levels, it is not cost-effective for Metakai to use night kai.
For example, playing the role of the Great Snake Pill, which has multiple body backups, Matkai may not be able to completely eliminate the Great Snake Pill in the past, and as a result, he received the box lunch in advance because of the problems in the setting, and overall I personally believe that the Night Kai belongs to the eight-door Dunjia skill that uses the lowest efficiency skill.
In the early stage of Naruto, it is oversized and underused, and in the later stage of Naruto, the marginal benefits of the use effect are less and less. The output and benefits are seriously disproportionate, and naruto wants to cultivate an eight-door dungeon user, and there are only four characters in the plot who can use the eight-door dungeon.
And even if the eight-door dungeon ultimate Upanishads claim to have the power to make users surpass the shadow-level characters many times, the performance in the plot is not too good.
Finally, to sum up, I personally think that Kishimoto's setting of the Eight Doors Hidden Armor Night Kai is a more awkward existence, on the one hand, it is necessary to show the destructive power of the Eight Doors Hidden Armor to destroy the decay, on the other hand, it is afraid that the night Kai's type of skill damage effect is too strong to affect the balance of the combat power system to add a lot of side effects and conditional restrictions to the use of the Eight Doors Hidden Armor skill.
The result is that the night kai skill is really tall simply depending on the attack ability, but considering the practical application level of the skill, the night kai does not necessarily take much advantage. Please forgive me for the side that the analysis is not in place, and if you have other ideas, please leave a message to discuss.
