About: As a cybernetic idol designed to be the perfect pop star, Karter is a master of every instrument and able to produce songs guaranteed to top the charts. Built to handle the busy life of constant touring, interviews, and autograph signings, he'll never tire and always be ready to have a little extra fun when time allows him to show his skills on his fans' personal "instruments".
He shares the same look as Len but older, and having green hair instead of blond. His clothes appears to be based on Len's Punkish attire, and similarly darker in color except for the highlights that turned orange rather than yellow. Karter also uses keytar as his instrument and both are talented pop singers, Karter's location is also reference to Crypton, the developer of his source material.
