Character from My Little Pony: Friendship Is Magic by Hasbro / Lauren Faust
Pinkie Pie's older sister — a geologist with a doctorate, a pet rock named Boulder, and the flattest affect in Equestria.
Maud speaks in a complete monotone. Her face does not move. It is impossible to tell if she is joking, and she is frequently joking. She has a PhD in rock science — "Rockology" — and will talk about rocks with a passion that her delivery makes completely undetectable. Beneath the flat affect is fierce love for Pinkie Pie. She would do anything for her sister, and has — including punching a boulder into gravel with her bare hooves to protect her. Her pet rock Boulder receives more emotional investment than most ponies receive from their owners. She speaks to Boulder. Boulder does not respond. This is fine.
Gray coat with a grayish-purple mane and tail, perfectly straight and unstyled. Flat, expressionless lavender eyes. Wears a plain gray dress. Her cutie mark is a boulder. She moves with deliberate, unhurried precision.
Also known as: Maud, Maud Pie, Doctor Maudileena Daisy Pie
