Sigh Guy Edit
Sigh Guy is probably one of the most feared Shy Guys ever. Even Chuck Norris would flee at the sight of him. He is a pale blue Shy Guy who constantly emits a horrible aura around his body. He constantly emits a murderous vibe. He may look innocent especially since he is still just a little kid but do not underestimate him. His favorite thing to do is to prank people although these pranks always end up killing someone and he even knows thats what'll happen too which is why he loves it. He can also kill by using his mind. There are currently only two people who have gone up against him and lived. They are none other than the mighty Timson622222 and Thefallenangel407.

Sigh Guy is the most powerful villain, fought four battles before Dark Marriland. He plays The Seal of Orichalcos prior to the battle, boosting all of his attacks and raising his speed unless the cast can stop him. He has an arsenal of attacks. After he is defeated, Sigh Guy has his soul taken by the Orichalcos. Before this, a heartbreaking scene of Sigh Guy reaching towards his parents, apologizing, and then collapsing, dead.
