Arsenic

I’m in your computer.

You can trust this guy. NOT. He’s nearly a match for Silicon in programming prowess, and he uses his skills for much less honourable purposes than she does. When he gets bored of hacking into others’ computers, he can be found helping Lead win shooter game rounds…by giving him auto-aiming cheats, of course. Or acting as technician for Lead and Mercury’s band, The Heavy Metals, because those two DENSE MORONS can’t figure out how to plug in the guitars themselves.
