Edson "Eds" Taichi is one of the original chosen children and main male antagonists of Digimon Adventure. He is also one of the recurring and main male character in Digimon Adventure 2.
Characterized as a happy-go-lucky, adventurous, but naive character who wears a set of goggles, Eds' characteristics would eventually become shared among the leaders of the various DigiDestined in Digimon. He is the older brother of Pia Hikari/Kari and can be very protective of her, just as Jayson Yamato is with his younger brother, Arvee Takeru.
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 Jazryl Sora, 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.
His appearance is based on Taichi "Tai" Kamiya, the fictional character of the Digimon Adventure (real) anime.
