Agon Kongo (金剛 阿含, Kongō Agon?) is a character from the manga/anime series Eyeshield 21. The younger of twin brothers on the Shinryuji Naga American football team, Agon is considered a genius player for whom the sport comes naturally - not least of all by himself - and treats everyone other than himself as worthless trash. However, he is forced to come to grips with his own arrogant ways and feelings when he faces the Deimon Devil Bats in the Kanto tournament playoff, particularly the trio of Yoichi Hiruma, Ryokan Kurita and Gen "Musashi" Takekura, of whom his actions allowed them to form a rival football team in the first place. He plays Wide Receiver during the Deimon vs Shinryuuji match.
