Hell Super Saiyan (HSSJ) is a transformation that can be achieved by any Saiyan. HSSJ is achieved by how much Hell Points you have. All a Saiyan must do to gain Hell Points is defeat a villain. Once the villain goes to hell demons tally up hell points and give them to the saiyan who killed the villain. If you have defeated one villain you can HSSJ, if you have defeated 2 villains you can go HSSJ and HSSJ 2, if you have defeated 3 or more you can go HSSJ, HSSJ 2, UHSSJ, and Hell Oozaru.
