In cannon, the Cyan Group was created specifically because of the Problem Children, who had to be moved because the other Group Leaders couldn't handle them, thus promoting Mrs. Katou and having to quickly get some cyan uniforms! Before these five Problem Children came, there were only 11 groups, but a 12th had to be made! The 12 groups are: The Orange Group, lead by Mr. Nyx The Teal Group, lead by Mrs. Viper The Green Group, lead by Mrs. Odysseus The Blue Group, lead by Mr. Roosevelt The Pink Group, lead by Mrs. Saxon The Purple Group, lead by Mr. McLean The Red Group, lead by Mr. Regan The Yellow Group, lead by Mrs. Harlequin The Grey Group, lead by Mr. Lucas The Black Group, lead by Mrs. Wood The White Group, lead by Mr. Alcaraz and the 12th Group, the Cyan Group, lead by Mrs. Katou
