Shaking his head, still trying to dredge up what memories he could, Arc followed the human female into the large room the voice had described. It was full of equipment of all kinds. Giving an appraising look over the multitude of weaponry, blades, and other feats of technology, his gaze fell on a nondescript block of metal sitting off in a corner. His eyes crackled with dim memories striving to be remembered, and he strode towards it. 

As he reached it and picked it up, electric currents flowed down his arms, and the metal began to shift in his grip. Sections of it began to elongate, other parts simply seemed to melt away. The change took nearly a second, and left him holding a large rifle, electricity crackling down and around its sleek form. Arc grunted. For the first time since waking up in that metal box, he felt something other than confusion or annoyance. 

Holding that rifle, he felt somewhat peaceful. Happy.
