Bizarre and eccentric, with a strange fetish for clipping toenails, the seventh guardian of the Book of Shadows is a highly unbalanced individual. He's germophobic, sociophobic and, oddly enough, photophobic. Needless to say, going out into public with him can be quite an experience.
Quiet and shy, he usually lurks in the background, hoping to slip by unnoticed. Remaining inconspicuous is not easy for this gentle giant, as his hulking stature and gas mask tend to draw lots of unwanted attention. A self-conscious misanthrope, Sly hides behind the other members when his paranoia and fear of people become too overwhelming.
Despite having his fair share of irrational phobias, he pulls more than his own weight within the organization. Extremely talented and intellectual, this social outcast is a prime source of creativity within the Brotherhood. The quintessential mad scientist, Sly invents much of the weaponry, vehicles and technology for the group. He once accidentally disintegrated another guardian when one of his experimental contraptions malfunctioned. His teammates jokingly say that he's a greater threat to them than to their actual enemies.
You can laugh at him, you can even call him a freak, just don't try to shake his hand or take his picture.
