Brunella Pommelhorst is a Physical Education teacher at Springfield Elementary School. She has blonde hair and is almost always seen wearing a whistle.
Ms. Pommelhorst takes a tough-as-nails approach to teaching and to life in general. When a teachers' strike took place at Springfield Elementary, she left her class the moment the strike was called -- even leaving a little girl clinging to gymnastics rings and calling for help.
She is also a big fan of Xena: Warrior Princess, to the point that she takes oaths by Xena. One such oath nearly led her to fail Lisa in gym class. However, in a rare break from her tough-as-nails demeanor, Ms. Pommelhorst relented and allowed Lisa to make up her grade by taking private lessons in order to pass gym.
In one episode, Ms. Pommelhorst announced to her students that she was taking a leave of absence to undergo gender reassignment surgery. According to Principal Skinner, she would be returning to the school as shop teacher Mr. Pommelhorst. However, she apparently decided not to undergo the surgery after all, as in "Moms I'd Like to Forget", she is seen standing next to Coach Krupt during the brawl that breaks out in the teachers' lounge after Mike insults Bart and the other 4th graders, still a female. She also appears as a female in the background of The Simpsons Movie.
- Ms. Pommelhorst's last name is very likely derived from the gymnastics apparatus the pommel horse.
- She replaced the former gym teacher, Ms. Barr. They both look similar, but Ms. Barr has brown hair.
