Flint from Spark the Electric Jester 2 & 3!
His hair was tough to get, so I hope it came across okay!

Originally a mindless worker robot, he miraculously gained sentience. Immediately after realizing his situation, he ran, until he was shot down. Luckily, he was found by another robot, Double, and they teamed up. After learning about Double's murderous lust, they fought each other in a battle that ended in a draw. Eventually fate would bring the two together again, as a trio (alongside Float) sent to turn Fark into scrap.

Spark and his games were made by LakeFepard and are available through Steam. They are the best 3D Platformers I've ever played, and you should check them out!
