Raremon

Raremon is a Ghost Digimon that is slimy and has a putrid smell that can knock others out. He tried to mechanize his body and live longer but he became like this because he failed to do so. The data that forms his body collapses and becomes scurvey, yet he lives and continues on. Because he has attack power and no intellect, he almost cannot win against other Digimon of the same generation.
