Demon Infernal

A is a horned Infernal, characterised by their more durable bodies, more powerful offence, and its ability to only be extinguished by extremely strong attacks.

Overview
Only a select few can become Demons under unusual circumstances; either artificially by the Bug, or naturally through Spontaneous Human Combustion. These type of Infernals are much stronger than normal Infernals, with skin that cannot be sliced by the Iai Hand-Sword Style, a technique by the strongest Fire Soldier Benimaru Shinmon, nor can be cut by a plasma blade. As a result, it requires a tremendous amount of power to destroy a Demon. Compared to normal Infernals, they have a much stronger heat signature. It is possible for Demon Infernals to also be sentient, as shown by Tempe.
