Mary is a student in Ms. Bitters class.


Mary is small, with a brown ponytail and a pink dress with a blue heart on the front.


Mary seems to be the embodiment of childlike innocence; she is perpetually naïve, and as happy as can be.

Role in Invader Zim

Frequently, her happy-go-lucky behavior is often used by Ms. Bitters as jumping-off points for her extremely dark lectures, which never fail to leave little Mary horror-stricken. For example, after Mary gleefully explained that she wanted to be a fairy princess for Halloween because she thought "unicorns and dwagons are pwetty," Bitters coldly claimed that she had once been a fairy princess too, but things "went horribly wrong" when she repeatedly flew into a bug-zapper. She was voiced by Antoinette Spolar.
