The current version of Dean Hardscrabble was modeled after a type of centipede called Scolopendra Gigantea, also known as the Amazonian giant centipede. One of these was brought in to Pixar for reference; the MU crew named it Kendra the Scolopendra. Hardscrabble’s personality resembles Anton Ego’s from Ratatouille. They even used the same phrase “Surprise me”. This is the reason I really liked her character. Also she’s voiced by Helen Mirren so FUCK YEAH!
