Carbon (full name: Carbon Christ) is a psychopathic Troop of KSD from Bad Fortress. He joins Mario's band in Section 1 to help him defeat Hoko Saba, but his ultimate personal goal is to end all fathers, as he hates his own father, Koopley. He has a soft spot for a small number of people, among them Mario, the Yoshi Kid, Koo Koopie, and possibly Bob.
