Anything he can

"Don't worry, citizen. I've got this under control!" Kate shouted out. She proceeded to run up to the criminal, wielding her bow like a golf club. She locked her arms back and swung straight at the criminal's head. However, at the last second, he flipped over on the ground and caught her swing. He then pulled her down into a kick that sent her flying backwards, straight into Jack. They were both down knocked onto the floor behind the countertop. Jack stared up at the ceiling, the whole world spinning around him. He took a second to regain his strength, and then groggily tried to stand up. The instant he did, he heard a loud sound follwed by a sharp pain in his temple. He had been shot. He looked around with his dying breath. On one side, the criminal, gun pointed straight out, mouth agape in shock. He must have been aiming for something else. Directly behind him was Kate Bishop, a so-called "superhero" who couldn't even stop a petty thief. Her shocked face was the last thing Jack Jordan saw before dying.

Dying was a strange experience. It was significantly more painful than Jack had pictured it, but the pain came with a sense of warmth that was altogether somewhat comforting. It was then that Jack heard a mysterious voice. It didn't really sound like the voice of a male or a female. It didn't really sound like any particular race, accent, or dialect. Despite being able to very clearly hear the words it was speaking, all that his lifeless brain could discern was that it was a voice. And the words it told him would forever change his life.

"Jack Jordan. Fate has not treated you kindly. At least, not in life. In ****, perhaps, a different story may play out. I grant you a power, one that you must not forsake as you have forsaken your life. With this boon, anything that bears your signature is yours. If you write on a house, than people will not enter it without your permission. If you sign an object, everyone will be hesitant to even touch it, even those with bad intentions. And, yes, if you sign another sentient being, they will follow your commands to the best of their ability, although it may not be willingly. You've already used one chance, make sure that this one counts."

Suddenyl Jack Jordan is back to standing behind the register, as a criminal that had followed him to work pulls out his gun and asks for some cash. However this time around, Jack doesn't just have a new power, he also has a plan. The world will suffer the way he did. They'll see soon enough.
