Mary Test-Johnny Test (Sfw 140 Photos) (Patreon)

Marrionette Louise "Mary" Test (born August 4, 1991) is one of the two tritagonists of Johnny Test. She is the older twin sister of Susan Test and the oldest of the test siblings. She is also the older sister of Johnny Test.

Mary is a super-genius twin sister of Susan and the older sister of Johnny. Like her sister, Mary harbors affection for the next-door neighbor Gil Nexdor, and attends school at the Porkbelly Institute of Technology (a.k.a Porkbelly Tech). The two are rarely (if ever) seen acting independently of each other, and work best in unison due to their shared high IQ.

Despite their similarities, Mary is more open-minded than Susan, but much less outspoken. While Susan sticks strictly to facts and realistic science, Mary is open to more hypothetical sciences such as extraterrestrials and cryptids, which often incites Susan's skepticism. Mary is also on somewhat better terms with their brother, due to her marginally higher empathy, though she is also highly prone to following Susan's more headstrong-attitude. She is 1 minute older than her sister Susan.

Mary has long curly red hair tied in a high ponytail and green eyes inherited from her mother. Her style of dress is very casual, especially compared to her sister's preppy style. She wears a pastel yellow shirt with a moon design. blue jeans, olive green sneakers with a moon design, white lab coat and a moon hairclip. Like her sister, she requires glasses to see, but she wears stylized frames with pointed tips.

For formal occasions, she typically wears a light blue dress with a magenta belt and flats.
