Mrs. Commanderson
From Homestar Runner Wiki
Mrs. Commanderson is some sort of bird/reptile that taught the Teen Girl Squad when they were the Teeny Tiny Girl Squad. In an easter egg in TGS 7 it is suggested that Mrs. Commanderson is also a member of the Cheat Commandos. Judging from her clawed wings, rows of teeth, and neck and tail length, Mrs. Commanderson is a particularly large Archaeopteryx, one of the earliest known animals classified as birds and one of the known evolutionary links between birds and dinosaurs.
