Lazer

Lazer was originally just an average nerd living in his grandparent's basement, until one day he was chosen for a special project from Weaponry Z.

They placed his brain inside a new robot body, now and forever becoming Lazer.

However, he had a tortured psyche before hand, so he killed everyone right after the procedure is complete. He now steals weaponry from across the globe, always muttering that one day he will destroy all of humanity. Until then, he spends most of his time bothering people online because he's actually a 12-year-old from Akron... or San Francisco... or wherever.
