Tai Kamiya, is a fictional character from the first two seasons of the anime and manga Digimon Adventure, and Digimon Adventure 02. He was the leader of the previous DigiDestined and Kari's older brother. He attends high school. He gave Davis his goggles to replace Davis' pair, which was wrecked in a battle.
As a brash person, he often acts on impulse without realizing the consequences of his actions. This leads him to moments of friction and guilt between his best friend and rival Matt, his oldest friend Sora Takenouchi, as well as his Digimon partner Agumon. As a true leader, however, he manages to do whatever is necessary to rectify the situation, and in times of need, save friends and family from certain doom. He is the bearer of the Crest of Courage.
After these events, Gennai calls Tai and the rest of the DigiDestined to the Digital World in order to give up his Crest power to fully revitalize the Digital World with a protective barrier. As a result, Agumon loses the ability to become MetalGreymon and WarGreymon. Fusion Confusion When he senses that Agumon is in trouble, he mysteriously enters the Digital World and tries to help him out. Along with Patamon and Gatomon, he finds a cave that has a Digi-Egg with the Crest of Courage on it. He tries to lift it up (and fails), which causes three points of light to rise and fly off. They are the three Digivices that Davis Motomiya, Cody Hida, and Yolei Inoue receive. After the battle with Monochromon, Tai also gives Davis his goggles, since Davis broke his square goggles in the battle.
