3. Sunlight on Snow

(Imperium, Valiant Entertainment)

Damn right, I'm using his preferred name. I'm not dead-naming a literal killing machine.

Sunlight was a medical droid that was reprogrammed by Toyo Harada to serve as his own personal weapon. Since the newly christened Mech Major wasn't a psiot, he could disarm psychic weapons ahead of Harada's invasion force. But the machine had its own mind. To prevent him from achieving the singularity and conquering Earth, Harada disconnected his mind from the internet, leaving him isolated.

But Mech Major discovered a dream he had, and re-named himself Sunlight on Snow, even though no one called him by that name. Buncha jerks. They'd regret it when SoS demolished them with his mechanical murder arms. As a member of Harada's Imperium crew, he worked alongside ethereal other-dimensional beings, alien murder assassins, and former terrorist government operations specialists. And he's arguably the most moral of the entire bunch.

He's a good machine, capable of multiple emotions and murdering a lot of PRS soldiers.
