Arm 15

Armando stalked through the wreckage of the reception area. He reached up to his left shoulder and tore off the arm composed of tungsten carbide. "I know they're keeping it here somewhere," he said. The offices of the Unusual Incidents Unit was nearly empty on a weekend, but the odd guard still managed to give him trouble.

He turned and sent his left arm flying down the side hallway, the condensed crystal structure barreling through a water cooler, and down to crash against the exterior wall. He followed it down, casually swinging the arm in his right hand, breaking windows, filing cabinets, and various federal office knick-knacks that dotted the cabinets.
