Digimon Adventure 02: The Alternate Destiny - Another End

Taichi is never a Chosen Child in the first place. It isn't the time. In exchange, Taichi's best friend became Agumon's partner. The fated time comes when that friend was saved from a certain fate by a time manipulating Digimon informing him that Taichi will take everything from him including his friends and his identity as a Chosen Child. He is not going to let that happen.
