Michael's an American kid who turns up during Series 2 in the DigiWorld. A friend of Mimi, his Digimon partner is Betamon. He was around at the same time as the kids in Series 1; he has an old Digivice. He asked Yolei out at the end of that episode, but I doubt it ever went anywhere, considering how far from each other they live... I mean, like he's just going to get in a plane and fly over to Japan for a date! Although I guess he could use the Digiworld gates.
