I'm with Xilinoc on this. People are speculating Engetsu's release is related to fire namely because of Engetsu's release command, "Burn". I, on the other hand, believe Engetsu's primary ability is energy manipulation. After all, last I checked, Getsuga Tensho was an energy-based attack, not a fire-based one.
