Kilik, using the Pot of Fire, engulfs his right fist in fire. He then attacks the opponent with a straight punch. He firstly used this technique against Hiro but the punch did not connect, so the potential of this attack was yet to be determined for a significant amount of time.
However; it was demonstrated again in combination with Medusa's Vector Boost, against a large magically mutated creature, where after it's protective magic coating was stripped, was defeated easily by the single blow of this ability. In this display, the techniques concussive force was so great, that it deformed the creatures entire body and destroyed a large portion of it.
