A powerful character might win or lose a fight for all sorts of reasons. That’s doubly true in anime , where character abilities evolve over time, and some power-ups might be fueled purely by emotional states.
Such is also the case in Naoya Matsumoto’s Kaiju No. 8 , which is set in a world where monsters named kaiju regularly trigger disasters. Apart from the kaiju themselves, we have to take the Japanese Anti-Kaiju Defense Force into consideration, as these skilled combatants are specifically trained to keep kaiju in check. The story follows Kafka Hibino, whose body is hijacked by a parasitic creature, which grants him the ability to transform into a humanoid kaiju. Concealing this aspect of his identity, Kafka enlists in the Defense Force to fulfill a childhood promise.
Warning : Spoilers for the Kaiju No. 8 manga/anime ahead
The destructive powers of a kaiju are measured via an assigned fortitude level. This also determines their class, like the stronger, more dangerous honju and the smaller yoju . Sometimes, kaiju develop fortitude levels that are considered abnormal, which earns them the classification of daikaiju . To even the playing field, members of the Defense Force fortify their powered suits with kaiju remains, which determines their strength, speed, and durability during combat. As these factors also rely on individual skill and experience, powerscaling characters in Kaiju No. 8 might feel subjective or tricky.
With this in mind, here are the five strongest characters in the Kaiju No. 8 manga and anime, ranked.
Image: Production I.G Gen Narumi has rightfully earned the moniker of “Japan's Strongest Anti-Kaiju Combatant” as captain of the First Division. Although Narumi remains formidable, he has never been able to defeat his former mentor, Isao Shinomiya, who had continued to train and improve himself in spite of his extensive experience. If we are to overlook this singular hurdle, Narumi is an absolute beast on the battlefield, being capable of defeating Kaiju No. 9's Beta duplicate and gaining the upper hand against Kaiju No. 11.
Apart from possessing the skill, speed, and durability befitting the captain of the First Division, Narumi has also awakened the RT-0001 weapon, crafted from the preserved retina and corpse parts of Kaiju No. 1. This grants him the abilities of precognition and pseudo-foresight, allowing him to parse electrical signals, temperature changes, and electron movements inside opponents. This split-second advantage helps turn the tide in most battles, as Narumi’s near-accurate attacks make dodging or blocking extremely challenging. This, combined with his bayonet and martial arts mastery, makes Narumi a prime candidate for one of the strongest characters. Narumi’s strength also lies in his excellent leadership skills, which go hand-in-hand with his eccentric personality and keen intellect…
