I wipe away your past to clear the scene, A ghostly boundary, clinical and clean. I steal your identity, erasing every trace, To heal a wound or leave a hidden space. A thin, synthetic skin that feels no pain, I guard from sickness and wash out the stain. What am I ?

I spin without wheels, I march without feet, A pulse of synthetic, a rhythmic heartbeat. I live in the darkness, the strobe, and the haze, A four-on-the-floor in a hypnotic daze. With cables and midi, I loop and I rise, Till the kick drum breaks open the concrete skies.

I am a symbol of authority, righteousness and order but add one letter and I become a dangerous lawless and chaotic omnivore.

If I'm black, Best for you not to attack, Else I'll whack Your nut sack

Made to keep sun out of ones eyes, worn backwards to keep your inner bad boy alive. I can alter your appearance to some degree, but I'll mess your hair up most definitely!
