The device pings again. A strong electrical jolt rings through your skeletal system, causing you to tense up for a second. Long enough to lose your balance, but not enough to fall over.
You look down at your body. Even in the dark, wet alleyway you can see it reshape into something smaller. But despite that: you feel yourself getting stronger. Your eyes pick up on the horizon which is getting a little closer. Then you realize you're shrinking. You are confused at this disguise. Smaller than before, but somehow stronger.
Your eyes now feel funny. Like something is being drilled into them. It's uncomfortable but not painful. You try rubbing them with your hands but this does nothing to the uncomfortable feeling. Then. Out of nowhere. The pain vanishes and you are left with a faint collidescope of colours. But as people walk past the alleyway, a square forms around their face and their private info appears. Their birthdate, their place of residence, where they work etc. 'Holy crap,' you think to yourself, 'So facial recognition for security purposes is feasible.'
Finally. Your clothes change to match with the surrounding area. They seem to be chameleon clothes in that'll change depending upon what's appropriate for the weather and area.
You're taken aback by all of this. The massive screens, the flying cars, the glowing tattoos. It's a sensory overload. In fact, the only thing that isn't different is the rain which is still just a cold as before. Although possibly more polluted.
You are admiring the city when you feel a presence behind you. You're about to turn around when you feel the cold metal of a knife on the back of your neck.
"Give me your money and you'll be fine," says a voice that sounds like it's from the street. Your heartbeat goes up and you feel your eyes dilate. There is a sudden unexpected rush of adrenaline. You kick the thief on their right kneecap. The sound of cracking bone fills the alleyway, followed by the wails of pain from the thief. You make eye contact with the wailing thief and turn back around. You've got to get out of here now. Somebody has definitely heard the bone cracking and the screams.
You run off down the alley. Confused at what just happened. Normally you would just hand the money over. But not this time. For some reason.
