If I grew a beard, it would not be hair, but thin red wires of METAL extruded from my face. A special METAL, not found anywhere else in the universe known as Brutallium. Single strands of Brutallium can be stretched and woven together to form the most awesome instrument strings ever conceived. From Brutallium pianos to Brutallium electric violins, everything becomes EXPONENTIALLY more METAL with the addition of these strings.
In fact, the Brutallium which flows through my veins is so potent that scientists are trying to find a way to form bombs which could possibly stabilise and contain it long enough to be dropped, and failing that engines which could contain the sheer POWARRRRR that it has as a fuel. Rocket engines ain't got shit on this.
As it stands I need special razors forged from pure Awesome to shave. And boy, they get pricey when the music industry gets cold feet and decides that supporting my habits is a risky investment, even though I do power the entire METAL industry.
