Official Bio
"To Dean Hardscrabble, there are scary monsters and there are all other monsters. It’s no surprise she feels this way—she is, after all, a legendary Scarer and Dean of the School of Scaring at Monsters University. Aspiring Scare students must be up for the challenge to impress her, though she is convinced that her assessment of who is truly scary and who is not is never wrong."

Trivia

 * Dean Hardscrabble’s character was modeled after a type of centipede called Scolopendra Gigantea, also known as the Amazonian giant centipede.
 * According to story supervisor Kelsey Mann, the dean was originally to be a male, who would scream and shout a lot. However, the team wanted to make the dean a scary figure, and found he wasn't really intimidating in this form.
 * In some ways, Hardscrabble appears to be the complete opposite of Waternoose: while Waternoose appears friendly and kind-natured but is actually cruel and evil, and is therefore and antagonist of the original film; Hardscrabble appears stern and unpleasant but is actually caring and benign, and is therefore an ally to Mike and Sulley.
 * Before the film's release, many believed Hardscrablle was the main antagonist, as many films taking place in a school (university in this case) usually have the principal (headmaster/mistress) as the antagonist.
