Thanks to the weapons 2, ISAO could not only use advanced combat forces, but also could release incredible sound attacks and massive energy emissions. It was more than enough to deal with Kaiju No. 8 in its strongest form and is one of the reasons why Kaiju No. 9 He targeted Isao to absorb his forces.

Weapon number 10

Soshiro Hoshina dominated

• Debut: Chapter 72 (manga)

Most of the weapons numbers in Kaiju No. 8 They were created before the beginning of the story, so they were all made with the remnants of various Kaija, which readers hear only in repetitions, but never actually saw before their extinction. The only exception of this rule was Weapon number 10that was created with the remnants one of the previous antagonists of the series, Kaiju No. 10. After all, he was a very strong and impressive opponent, so it makes sense to make a very strong weapon.

No. Soshiro Hoshina. Weapon 10 numbers were a valuable benefit in an intense struggle against Kaiju No. 12, Which should be the final and improved version of Kaiju No. 10. Hoshina was perceived for most of her career as inferior in defense forces because he specialized in Blaladed Weapons and could hardly use firearms. Although he showed how qualified he is, weapons 10 finally equalized the playing field for him. With the help of force no. Even better, this weapon kept part of Kaiju No. 10, which gave both the new owner, fun dynamics and many heartily charming characters' development.

Honesty

Weapon numbers 3, 5 and 7

As already mentioned, the original Kaiju No. 8 Mango has already ended and naturally left fans with many hot questions. One of the largest is the fate of weapons of missing numbers, namely those that were made with the remains of Kaiju No. 3, Kaiju No. 5 and Kaiju No. 7. Where are they? What are they doing? Who is currently controlling them?

The fans expected that the weapon 3, weapon 5 and weapon numbers 7 would appear at a certain point in the story, but unfortunately (and strangely) it never occurred, so it left a lot of missed potential on the table. However, it is still possible that three weapons from the missing numbers may be revealed in additional material in the future in the future, such as manga, spin-off mango or an anime original episode.
