The strongest kaiju in Kaiju No. 8 manga

Kaiju No. 8 (also known as Monster #8) is a fantastic series drawn by Mangaka Naoya Matsumoto, all about the fighting of the Japanese defensive force against the ubiquitous threat of Kaija in a fictional world. The term “Kaiju” in English basically translates into “Monster” (hence two manga titles) and presents the entire sub -media in the Japanese film, mango and anime of giant monsters.

In order to name some of the most important examples, there are all media based on Godzille (of course), King Kong and Ultraman. But what did the fearsome kaiju appear Kaiju No. 8 So far and how do they accumulate when they put on side by side?

Updated September 2025 Julian Fernández Loyarte: Not only is the 2 in Kaiju No. 8 anime currently broadcast, but the original manga also ended on July 18, 2025. Due to these two main developments, this list was updated again, with some records to make the last chapters of mango and the new record for the final boss of this series.

Renunciation of responsibility: The items below contain some heavy spoilers for Kaiju No. 8 Anime, because manga is much further in the story than anime adaptation.

13

Mixogster

Big but strange fungal type kaiju

Unfortunately, this first item is the only “numbered” kaiju, because the rest of the ranking is made up of all Daikaiju, which JDF could not defeat on the first observation, which then required to be identified when backup showed. This fungal type kaiju (better known as Mixogster) First, it will appear in chapter 12 Mango, where new defensive power recruits are brought, including the “cadet” of Kafka Hibin to help reduce it in their training.

Now, at the basic level, this monster is obviously something that JDF can do quite easily, because the main body was balanced without much effort Gigantic Cannon Miny Ashiro, while the rest of the soldiers cleaned its offspring. This means that if Kafka did not climb into one of the corpses and found the implanted egg-SAC (modified Kaiju No. 9), these smaller descendants of animals would be maintained long after JDF left the scene, causing damage. In principle, he is the head of a monster, but rather a weaker mini-chief than a real boss.

Kaiju No. 10

Also known as the numbered combat suit Soshiro Hoshiny

Here is another Kaiju who introduced the story by issuing the “challenge” of the kinds of defensive force, Kaiju No. 10. This creature animal is the one who used Draconic-Typ flying kaiju to organize a raid on the base of Tachikawa's third division. Now, individually, Kaiju no.

This means that this prototype Kaiju created No. 9 has some obvious shortcomings, the largest of which is his personality, aka his desire for a good battle. Since No. 10 was looking forward to the third division, Soshino Hoshiro, he gave his initial goal to destroy the base on the back burner, which eventually led to his defeat and possible state of the numbered weapons.

11

Kaiju No. 1 (RT-0001)

Future look kaiju

The next is one of the first kaiju in the series, which is only “seen” in its form. For the numbered daikaiju it is jdf from a place to take corpses after being defeated and turned them into a weapon, similar to something like quinque in Tokyo Ghoul.

It's not much known now Kaiju No. 1In addition to the fact that it was a “future look Kaiju” and the first “numbered” Kaiju. But from what the readers saw from the Narmi gene who used their strength placed in his eyes, it must have been an incredibly impressive animal.

10

Kaiju No. 2 (FS-1002)

Calamity Sapporo

Be a weapon controlled by the CEO of the Defense Forces, Isao Shinomiya, Kaiju No. 2 When she was alive, there must have been a real threat. And from what readers currently know about Kaiju No. 2 before it was a weapon, it seems true. Kaiju No. 2 was a monstrous monster that destroyed Sappor almost with almost one hand before it was eventually removed.

He was known for his monstrous strength, pride in her strength, sound explosions at the level of buildings, and even unleash the explosion of electromagnetic energy. While its overall forces are relatively basic and somewhat similar to Kaiju No. 10, the range of these forces and the size of the dwarf kaijus, which showed No. 10. Shinomiya and absorbed his numbers weapon.

9

Kaiju No. 14

Designed to teleport from bullet miny ashiro

The next five Kaiju on this list is in this “vague” gray area in terms of ranking, in this “vague” gray area. See, named Kaiju's 11-15 were made Kaiju 9 and were quite literally designed from the ground up to directly face very specific members of the defense forces. Kaiju No. 14For example, it was seemingly created as a counter for Mina Ashiro, a specialist in defensive forces. Kaiju No. 14 could fly, he could shoot highly destructive rays from his mouth, could generate strength fields and even teleport.

The general tactics of this Kaija should have caused as much damage as possible and constantly teleport to different places in the area so that Mina Ashiro can never “lock”. While it worked for a while in the fight against Mini's combat style, in the end it overcame it and there are a lot of captains of the defensive forces and captains of the Vice President who would have a relatively easy time to fight this Kaija.

8

Kaiju No. 13

Movements really fast and was also defeated really fast

Another is one of the five above -mentioned Kaiju the other wave Kaiju No. 8that is being Kaiju No. 13. This one did not receive almost as much time to demonstrate his skills as the other 4 (11, 12, 14 and 15).

This is because No. 13 has reached Kafka Hibino quite quickly, which recently tricked the whole ton, because Kaiju No. 8. Fans know that this Kaiju had the ability to run and fight incredibly fast speeds and also seemed to be able to improve (and enlarge) muscles. However, none of these attributes was enough to build a real fight against Kafka, making it one of the weaker numbered kaiya of this arch.

7

Kaiju No. 11

Designed to face the “reading of the mind” gene Narmi

As well as Kaiju 14 was a direct miny Ashiro counter, this other kaiju (aka aka (aka Kaiju No. 11) He was a direct counters of Narmi gene. Using the memories of Isao Shinomiya Kaija No. 11, he knew exactly how gene's numbered weapons worked and used their capabilities of hydrocinesmine to basically prevent the gene in predicting attacks by electrical signals.

Outside the manipulation of water, Kaiju No. 11 is not so special. He had a high resistance, was very strong in terms of strength and could turn his body to meet his needs, but the only “special feature” that the hydrocines had. As soon as the gene came on the road, the postponement of Kaiju No. 11 was quite easy. And any other vice -president or defensive captain would probably have a great chance to defeat Kaija 11, because Kaiju could not use his skills to face the struggle style of this defensive force.

6

Kaiju No. 12

Designed to beat Soshiro Hoshin in close fighting

Kaiju No. 12 It's hard to place. It was obviously designed as a direct counter to the vice -president Soshiro Hoshina and the “improved” version of what Kaiju No. 10 was supposed to be, but that's why it is difficult to include it. His battle against Vice President Hoshina was incredible and pleasing to read because Kaiju 12 really pushed the captain to his absolute limits.

However, if any other vice -president or defense captain fought Kaiju No. 12, it could be much faster. Kaiju 12 was again designed as a specialist for a close range that could do what Soshiro Hoshina did, but better. So if the number 12 went against, say, Mina Ashiro, it is very likely that it would be very easy to go from a distance due to the minor absurd level of penetration using weapons.

5

Kaiju No. 15

Designed to end Kikor Shinomiya

Mental attacks are incredibly difficult to deal with. Granted, Kaiju No. 15 They were given these mental abilities as a way to beat Kikor Shinomiya, but through their own memories of her family against her. Unlike all other Kaiju in the second wave arch, however, Kaiju No. 15 would probably be difficult for each member of the defense force.

The mental abilities of Kaiju 15 allowed her to dig memories of the person associated with, manipulate said trauma and much more. Everyone has some problems with which they work with almost every stage of their lives. So, when we have to go through these problems at the moment to fight one of the strongest kaija in existence, there is something that every member of the defense forces would face, let alone Kikor Shinomiya (due to the whole of his recent trauma).

4

Kaiju No. 6 (EC-0115)

Literal king of Kaija

If this list was evaluated where Kaiju No. 6 Currently, she would sit as a weapon number controlled by Reno Ichikawa, it would probably be close to the bottom. But Reno has recently become capable of using even the overalls No. 6, and even when weapons made of numbered Kaija are not confirmed that they contain “all” the power that Kaiju used when he lives.

From what the readers have seen and heard of Kaija No. 6, aka “King of the Kaiju” (which seems like another Multiverse Kaiju-king), it was almost certainly the strongest kaiju. When it ran, she killed over 200 members of the defense forces and also the wife of Isao Shinomiya (mother aka Kikor). If it was the current threat in the story instead of the weapon used by Leno, Kaiju No. 6 would probably handle all the other monster on this list at the same time and still came out.
