Masky wears a yellow jacket, black/grey jeans, black boots, and a mask that shows his eyes but the bottom of his mask doesn't show his mouth. His weapon is a crowbar or a rock show he can smash his victim's head.
In the beginning, Tim wasn't a nice man. He was more a agressive, selfish man. After getting the Slender Sickness, he was even more rude and violent. Becoming a proxy made him even worse. He can be nice and caring sometimes, but only if you make him.
Tim was driven into Slender's Sickness, which caused him to go insane; Soon, when he reached the edge of the illness, Slenderman took control of his Soul, since then Tim became Masky and also became a Proxy of him, unable to escape unless Slenderman returns his soul back. What he doesn't know is that Slenderman doesn't care about him, thus only using him as some kind of puppet that kills for him.
