Igor is a driven physical deaducation teacher, always on the lookout for ways through which he can get the students to start running. However, while his presence is somewhat feared for this attitude, Igor has only the best interest of his students in mind. If he knows it is not a good time to force physical deaducation on them, he won't.
While it is likely that Igor is some kind of monster, his horror niche is that of an Igor, a stock character characterized as a deformed assistant in service of a mad scientist.
The "misfigured assistant named Igor" stock character finds its origins in the first stage adaptions and 1931 film adaption of the horror novel Frankenstein. No such character exists within the actual book, and in the adaptions, the character is called Fritz, not Igor. A similar character appeared in the film sequel, Bride of Frankenstein, but called Karl. The first use of the name "Igor" or "Ygor" comes from the 1933 horror film Mystery of the Wax Museum and was later again used in the two Frankenstein sequel films, though while both Igors are disfigured, neither are disfigured in the common-Igor way or are assistants. Exactly what factors made the name "Igor" tightly connected to the misfigured assistant-character are unknown
In "Photo Finish", Coach Igor took over study howl on Picture Day, much to the horror of Clawdeen Wolf, Draculaura, Cleo de Nile and Frankie Stein. Fearing he would make them run laps and ruin their looks with sweat, the four made a run for it while Igor choked on his whistle. Running all the way up to the bell tower, they thought they had lost him, but Igor proved otherwise. Catching up with them, he informed them they were free from study howl to prepare for the pictures. At that time though, the girls had exhausted themselves in trying to escape physical deaducation and ended up photographed looking terrible.
