Very little is seen of Friedkin outside of Judy's training montage, but from what we can gather in that, she appears to be fairly passionate and loud, employing emotive language and low-level insults for the duration of the time we see her.
Role in the Film
The Major is only seen in the beginning while Judy Hopps is training to become a police officer, consistently criticizing her for a perceived lack of ability and shouting demeaning names.
However, Judy is seen improving greatly, and soon becomes top of the class after doing intensive personal training. The Major is implied to be impressed with the rabbit's improvements.
