Ms. Mason has brown eyes and long brown hair which she ties up in a high ponytail with a blue barrette. She is normally seen dressed in a pale yellow pantsuit with a blue top underneath, together with brown court shoes.
Ms. Mason is very serious and somewhat stern, and is not very friendly. However, like most teachers, she seems to be very patient and understands that some things may take a lot of work. She always has a heart in the right place where it comes to sometimes being nice to students.
