Doom 2016 - Mancubus

Mancubi have taken their disgusting physical condition and turned it into a weapon. As they reach maturity, a chitinous growth begins to form over each hand, creating a hard sheltered "barrel". As the flesh inside decomposes, a noxious effluvium begins to leak from the barrel. The Mancubus can spew this discharge from the barrel over a remarkable distance. The volitale goo ignites under the tremendous pressure, creating a highly effective biomechanical flamethrower.
