Yamato "Matt" Ishida
Matt's in high school now and he's swapped his harmonica for a bass guitar. He has his own band, the Teenage Wolves, and he's trying to make it as a rock star. His stage name is "The Digidestined Formerly Known As Matt". Matt and Tai are still friends and rivals. Davis' sister June has a huge crush on Matt and is always chasing him. Needless to say, Matt doesn't feel the same about June.
I'm not sure what's with the hairstyle. IMO, his old hair was better. A lot better.
