I'm a superhuman enhanced with ungodly cybernetics

"I'm a superhuman enhanced with top of the line cybernetics. You either choose to serve me, or your life is forfeit," you say determined.

You realize you were backed into a corner here. With only one feasible way out: and that is the way of the Voice. An ancient menace that seems superficial, yet had many beholders throughout the millennia. A voice, a tone, a form of speech, where the words themselves do not matter. A voice that could one day lift mankind to a new level of existence, far above it's current petty grievances.
