Terror had been planning for days.

Well planning was an over statement it was more of Terror just thinking about the same thing over and over and over again. He had heard about a hero in his town HIS town which he had to bring a stop to. Terror had been stalking the hero named Shade for the past few nights getting an idea of any patterns in patrols or little bits of her fighting style. Tonight was the night he would strike. She didn't suspect anything sitting there with no suspicion of her incoming demise. Terror aimed his wrist at her silently from behind and with great speed shot a dart at her.
Only it didn't hit her.
Instead it hit a robotic monstrosity straight in its head just as it had dropped down from who knows where. It wasn't dead by any means and was still wriggling around getting up but he had definitely hit something important.
