Guiyii is a character who appeared in The Rise of Sqeegee 7. He was created when Weegee stared at a mirror. In the Rise of Sqeegee 7, he attacks the King and Robotnik while they're having a fight, and then Demon Sqeegee and Dark Sqeegee attack all of them. Guiyii takes on Dark Sqeegee while the King and Robotnik take on Demon Sqeegee. He can make people go into a trance where he will spin around and everything goes G-Major except for the victim(s). He uses this twice in ROS7, once on the King and Robotnik and the other on Dark Sqeegee. Guiyii is very powerful, as he was able to single-handedly take on Dark Sqeegee. However, he is likely not as powerful as Weegee. Despite never appearing in the series again since then, his brother Marreoh appears in The Rise of Sqeegee 8, though not for as long as Guiyii did in ROS7. He also has a clone named Leegee who was introduced long before ROS7.
