In the Digimon movie we meet a new Digidestined. He is not Japanese like the others we have seen. Then later on in Season 2 of the television series, we meet Michael another Digidestined from America. Then right at the end of Season 2 we meet Digidestined from all over the world. These are not all of the Digidestined in the world but only the ones that we know of.
Here is a little info on the international Digidestined, but unfortunately we have very little info on them.
