Kaiju No. 15 is one of the numbered Kaiju that was specifically created to defeat Defence Force prodigy, Kikoru Shinomiya. It was created by Kaiju No. 9 and bears a striking resemblance to Kikoru, with the only difference being her black hair, which contrasts with Kikoru’s blond hair.

Kaiju No. 15 has several impressive abilities, and being created after such a genius in Kikoru is testament to her power. She was able to keep up with Kikoru and is strong enough to be recognized by her creator. Able to fly, regenerate, and shoot energy beams, Kaiju No. 15 cannot be underestimated.

The duo of Aoi and Haruichi is something of a pair. While the two have different personalities, in terms of abilities, they are basically on par with one another.

When they started out, Haruichi was able to draw out more power from the Defense Force Suit, but they have only grown stronger together. While Haruichi still draws out more power from the suit and is an excellent marksman, Aoi is absolutely no slouch and holds his own.

Human

Gender

Reno is one of the earliest characters introduced to the story and has been the one on Kafka’s Hibino’s side from the very beginning. His strong resolve to join the Defense Force and defeat Kaiju is one of the reasons Kafka was able to even make it through the Defense Force exams.

Reno showed an early affinity for the ice element, favoring ice bullets in his battles before finally acquiring a ‘numbered weapon’ which was also affiliated with ice. This has greatly enhanced his battle prowess, and his resilience, which he showed in abundance when facing Kaiju No. 9 for the first time.

Daughter of the esteemed Isao Shinomiya, Kikoru was raised to be strong. After years of training and conditioning, by the time she got to the Defense Force exams, she was already the best. By the time they unleashed the power of their suits for the first time, she was already getting an output of 55%.

Kikoru possesses incredible speed, immense power, and a calculating mind that enables her to think through her battles pretty well. She was the first recruit to get a numbered weapon as she was compatible with No. 4. Her devastating power sets her way above any of her peers, and with the frightening ability to grow even more.

6 Mina Ashiro

The Most Inspirational

Species

For many of the younger members of the Defense Force, Mina was the reason they joined the Force with her quiet grace and impressive competence in taking down Kaiju, she is one of the youngest heads of a squad. As a childhood friend of Kafka Hibino, she is also a driving force for his continued struggle to stand by her side.

Mina is an incredible marksman, and her skill with the impossibly powerful T-25101985 cannon is one of the things that make her so strong. Able to deal with Kaiju from long range with unerring accuracy has been her strategy in defeating the hundreds of Kaiju she has taken down in her career. She’s also able to reach almost 100% output from her suit, which is really impressive.

He Never Gave Up

Species

Human

Gender

Male

Height

Soshiro Hoshina is the vice-captain for the third division of the Defense Force and the man who currently stands beside Mina Ashiro. Born to the famous Hoshina clan, who have been around since before the Muromachi period, he is also the one who has acted as a more hands-on mentor to many of the recruits into Squad 3.

While Soshiro is a vice-captain and considered weaker than Mina, the fact that he can handle close combat and is even stronger than Mina in such combat makes him a very terrifying enemy. He was able to keep up with both Kaiju No. 8 and 9 in combat even when severely disadvantaged. His speed, over 90% output from his suit, and accuracy with his blades make him deserving of a high spot as one of the strongest.

4 Gen Narumi

The Unstoppable First Division Captain

Species

Human

Gender

Male

Height

Gen Narumi is so strong that Isao Shinomiya had to continue training just to remain a goal for the gifted captain to reach and keep motivated. Gen was there during the fight between Isao Shinomiya and Kaiju No. 8 and was the fastest to react when he turned human again, almost ending him there and then.

Gen is able to predict what enemies want to do and was strong enough to easily dispatch of the Kaiju No. 9 clone. He was also able to keep up with the original, and his speed and precision make him a very fearful foe. He’s the closest captain to achieve 100% of the suit’s output.

3 Shinomiya Isao
