Bernard "Bernie" Kropp is a supporting character in The Incredibles. He is occasionally referred to as "Teacher" or simply "Bernie." He is Dash Parr's teacher. He is initially seen in the principal's room as Helen Parr arrives and informs her that Dash is an annoyance whom he openly mocks in front of his students. Dash tries to clarify, but Bernie shouts angrily at him, claiming he put thumbtacks on the seat. Helen asks him if he witnessed him do it, and he answers that he did not. She is surprised, and she asks how he knew it was Dash, and he informs her that he hid a camera.
His hidden camera, however, captured a blur from Dash's seat to Bernie's chair just before and after the trick. Fortunately for Dash, Bernie is rejected as being too dramatic and obsessive, owing to the fact that the video didn't capture Dash's motions particularly well. Bernie gets scarlet and throws an exceedingly infantile tantrum as Helen locks the door after Dash is exonerated of any duty to his parents and the school board. Bernie is not seen again throughout the rest of the film.
