Stage 5 Transformation - "Black Dragon" (5단계 의태 - 흑염룡) is the name of the Ruel Mon's stage five Canine Partial Transformation. This canine transformation form will transform Ruel Mon's right arm into a black dragon's head, starting from his elbow and going down below to his fingers. The dragon head is gray with three pairs of eyes and two large horns going out from the top of its head. The dragon head is attached to Ruel Mon's arm by the back of its head and its mouth is compromised of several large teeth which Ruel Mon can use to grab things with. [1]
