The situation was getting ridiculous, really. This was supposed to be a simple job, hell, it had been a simple job. The safe she was breaking into was a fairly good one, but no match for her technology. No one was in the building, and the alarms had been deactivated, and the safe itself had been quite literally ripped open. With her arm, she saw no need to waste time with listening to tumblers or hacking through a lock, though she certainly could have. She had done so before she lost her arm, and had it replaced by a rather mysterious benefactor. She had been in the process of loading up the cash, gold, and papers from the safe into a backpack when the screaming had started outside.
A glance outside revealed the situation in a heartbeat, a group of strange apes were making a mess of the neighborhood. A couple of them were overturning a semi truck, and another was chasing one of the luckless man who happened to be in the wrong place at the wrong time. Worse news for her though, was the news helicopters flying overhead, pointing cameras every which way. So much for no one noticing her there. Besides, despite herself, she didn't really want to sit around and let the fleeing man get eaten. It was only a matter of seconds before the ape caught up to him.
Sighing, she put on the loaded backpack, and went up to the window of the story she was on, and opened it up. She aimed down with her robotic arm at the fleeing man, and fired. There was a soft whoosh, and her hand shot down to the man and landed neatly on the back of his collar. The man screamed and thrashed, probably thinking the ape had grabbed him. Fortunately, he didn't shake off the hand, which gripped his collar. The hand started flying up, hauling the man up to the window that Amanda had opened, and pulled him inside. The ape below howled angrily at its intended prey being snatched up out of its grasp.
"Shut up, and don't waste my time," Amanda said rather irritably, cutting off the man's gasping thanks as the hand reattached itself to her wrist. "Make for the stairwell, and go out the back door, it won't be locked," She paused a moment, and heard the ape from below climbing up the outside of the building to her floor. "And hurry. Things are going to get dicey around here." She added, as she heard the roaring ape approaching. The man scrambled away and out of the room as the ape came to the window. It's beady eyes fixed on Amanda, as it tore out the window and a good chunk of the wall. Amanda only brought up her metal arm again and aimed it at the ape.
"Sorry, saw King Kong already, and it sucked. Not in the mood for a sequel," She said, firing her fist again. Unlike the relatively gentle touch it had with the man, the hand shot off at full force this time. A blue thruster flame shot from the back of the hand as it rocketed towards the ape. The fist caught the ape square in the chest, blasting it back away from the building. Amanda just summoned her hand back as the ape screamed as it fell. "Now, to get out of here myself." She said, reattaching her hand and leaving the window.
