9. Kyoraku Shunsui
Although he looks a bit “stylish” with the familiar pink Kimono shirt with colorful patterns, he is still a professional combat expert, extremely strong and intelligent. He is one of the strongest captains with his mastery of Shunpo, taijutsu, and skillful movement. Kyoraku Shunsui was the former captain of the 8th division and was later promoted to the captain and captain of the 1st division.
10. Hitsugaya Toushirou
Despite his appearance as a young man, Hitsugaya Toshiro is already over 100 years old. Toshiro is considered one of the best captains in Gotei 13. He can control even the Ice Dragon – the dragon that can freeze anything. His swordsmanship is also very good, which makes him one of the most reliable Shinigami, especially in battles against extremely powerful opponents. Hitsugaya is currently the youngest of the 13 Gotei captains. Before becoming the captain, he was a Tamchi under the former captain of the 10th squad – Shiba Isshin (Kurosaki Isshin) – Ichigo’s father.
11. Shihouin Yoruichi
Yoruichi certainly retains her old position as a captain and Commander-in-Chief of the Stealth Forces due to her strength in Bleach including when she immobilized Espada Yammy Riyalgo with her bare hands. While she is highly skilled in all of Shinigami’s combat tactics, Yoruichi has always been described as being very strong in hand-to-hand combat, and using footwork, an ability to move at high speed. Her movement speed is almost unmatched by anyone and hence she is known as the Flash Master. Yoruichi is also skilled in “Flash Cry”, an advanced fighting technique that combines hand-to-hand combat and kido abilities. The use of a shunko allows the user to use their bare hands to block an opponent’s weapon without being injured.
12. Kurosaki Ichigo
Since Ichigo Kurosaki is the main male character of Bleach, it doesn’t take much to understand how strong he is. Ichigo is a high school student with orange hair, Ichigo becomes “Substitute Shinigami” after accidentally absorbing most of Kuchiki Rukia’s power. He is considered the most dangerous person in the list of Special Forces. Ichigo’s skepticism at first made it difficult for him to handle cases, but as time went on, he began to accept and welcome the power of the Shinigami.
