Hayato Kobayashi is a character that appears in Mobile Suit Gundam.
Hayato was a serious boy with a strong sense of responsibility and cooperative spirit. On the other hand, he had a stubborn streak, and at one time he even left the White Base in opposition to Bright and others who favored Amuro. He also showed an aggressive side in the fight against the Principality of Zeon. When Char Aznable infiltrated into Side 7 and came close to the White Base, he took command and intercepted him. He is said to have been a brave character. However, he would often measure himself against the accomplishments of others, which led to him having insecurities.
As a pilot, Hayato was not as good as Amuro, but he gained experience in actual combat and grew into a full-fledged warrior. It was also during this period that he developed a tactical sense that would later be utilized in his command of Karaba, and he would sometimes give advice to Bright. He had been an avid practitioner of judo since he was a civilian, and once knocked down Amuro, who was so enraged by Ryu's death that he attacked him.
