He called "chītā" (cheetah) because he was so fast with his answers and combat. Easily one of the best students, Kai was looked to solve problems on the spot. Sometimes the solutions to the problems he gave were a little too advanced. Nevertheless his solutions would benefit the situation at times.

Throughout his training with his team, when forced to fight enemies, Kai would give them the benefit of the doubt, most of the time, to see what they've done. But if he has too, Kai will defend and become from his aggressive side.

His relationship between Naoto was a rivalry intact. Kai always knew Naoto was a great adversary of him, and Kai personally wanted to fight him. During Part II, Kai still had the same mindset as he did when he was a child. Kai often smiles a lot and likes to laugh when he is with his friends. Still cheering people up and smiling every time he saw his friends, but in battle his demeanor became more serious. He showed that if anyone threaten his friends, then another side of him would come out. The protector side will let loose. He acquired this from his great-grandfather Hashirama Senju, which later he discovers that he is a Sage.

After the final fight with Naoto, Kai realized that beyond all that negativity in the shinobi world, the new generations would rebuild and keep rebuilding until hope is turned into a reality. As the fight between Naoto and himself, Naoto admitted defeated towards him and laid beside Naoto. His hand was grasped by Naoto and he vowed to be protected by him. Both of them were lifted by Hideo and stared at each other smiling, knowing that their friendship is even more valuable. Now as a father, Kai shows his love towards both Aykane and Kaijin. He shows them how much he loves them by buying them gifts all the time and spending time with them.

As a father, Kai releases that his son is just like him.

For his alternative outfit, he just wears a bright blue t-shirt and ankle length black pants, also his hair is in a low ponytail. In Part II, Kai's hair is longer than before.

Abilities
Kai is deemed for a having great use of the Wood Release. Due to this, he uses an insane amount of chakra and dabbles into taijutsu to compensate for it. Upon learning Sage Mode, Kai was able to subdue his chakra and advance it when he needed too. He never struggled in basic ninjutsu, taijutsu or genjutsu. In Part I, Kai's sense of skill and passion, landed him a role in sparring and training with both Neji Hyuga and Rock Lee. All three matched in combat and in jutsu, canceling each other attacks left from right. Although the sparring helped Kai, he need further guidance.

After training for two-and-a-half years with Neji Hyuga, Kai expanded his knowledge and power into something unbelievable. His power almost match that of the The First Hokage, Hashirama, who Kai lived up too.

Taijutsu
As a member of the Mori clan, Kai is skilled in his taijutsu skills. His taijutsu skills come from training all day and night. Hes able to trip up specialists. At first Kai had trouble countering and focusing on keeping his breathing in tact. During the Chūnin Exams, Kai showed that he was very fast, quick witted, and bombastic. He matched the speed with close combat that of Neji Hyūga, and the quickness of Rock Lee. His training with those two really gave him a strength, speed, as well as a knowledge boost during the preliminaries.

Kai has shown incredible speed and raw talent. He saved Aykane from a thrown boulder, from an enemy Earth user, witch only a cut on his thigh. Even while exhausted, Kai can keep up with Rock Lee without his ankle weights being on.

Kekkei Genkai
Kai inherited the Wood Release from his father and great-grandfather. In the beginning of his shinobi training, Kai was unable to use it, since he was so inexperienced. The ability became unlocked when Kai learned that his great-grandfather was the First Hokage. He used that to his advantage to master his given Kekkei Genkai.

He mastered his Wood Release technique by ranging out and flowing through nature transformations, guiding himself through his newly found ability. In a dying forest, Kai brought its life back by clapping his hands together and letting his energy flow through him. The forest regrew but even larger and more brighter. Reasoning from this happening was because Kai had such a big heart, and the chakra overflow gave the plants more life.

In later years, Kai is able to form the Wood Release techniques without using his hands. By now, he can create massive forests, but half the size of Hashirama, and also create armor. He uses his Wood Clones with him in battle without using a lot of chakra. While in Sage Mode, Kai's Wood Release increasing severely. He can now create large pillar prisons and dragons.

Being a Senju, Kai already had the cells from his great-grandfather, Hashirama. Kai was not able to enter Sage Mode at first. He didn't learn how to control his Wood Release .

Now once Kai accepted his Wood Kekkei Genkai, he entered Sage mode and met Hashirama. Kai is very skilled in his Sage Mode, enhancing many of his jutsu, especially his kekkei genkai. While in this mode, he can fall from various heights without the result being in death. He can also push through barriers, and walls without being harmed. Another ability is to glide into the air as an illusion of flight, making it easier to activate his jutsu.

Sensory Perception
After mastering Sage Mode, Kai can detect and identify other people's chakra from vast distances. With this, he was able to locate a foe from attacking him from a far distance. Now with this, Kai can dodge and locate an enemy from miles away.
