Ms. Ruthless Donatello is the English teacher for Hills Village Middle School and the leader of after-school detention.
Donatello is a big influence on Rafe as he goes by in his sixth grade year, but is mostly a enemy in Rafe's opinion. Rafe thinks she and his mom can be friends due to the fact that they are both artists. She is trusted by Ms. Ida Stricker, the vice principal , as well as Mr. Dwight, the principal.
Donatello is sometimes shown as a fire-breathing lizard, but in one picture, Ms. Donatello is shown with black or brown hair, down, a sweater over a shirt, a skirt, high heels, glasses, and earnings.
