Principal Irving Slimovitz is the principal and teacher of mathematics at Norrisville High.
Appearance
Everyday
Distinguishing Slimovitz is an altitudinous, slender figure with retroceding onyx-black hair and bodacious chartreuse eyes. Oftentimes, he caparisons spectacles, a kempt white turtleneck shirt underneath a svelte gray vest, and a brown jacket complemented by compass-blue trousers and burnished black shoes.
His alternate ensemble subsumes a honeydew-colored shirt, a voguish sweater vest embellished with pickle-green and marigold-colored accents, seaweed-green trousers, and a satin black tie, yet his black shoes remain a constant in his apparel.
Stanked Form
When suffused with the Stank of the Sorcerer, Principal Slimovitz undergoes a metamorphosis into a sinewy, humanoid monster distinguished by blue skin blazed with dark blue stripes.
Personality
Slimovitz is a somewhat aflutter yet perpetually optimistic individual--often resorting to antiquated vernacular, much to the delectation or chagrin of his students--and, despite the school's periodic skirmishes with monsters and robots, Slimovitz remains auspicious for futurity with the school premises suffer from invariable devastation. However, he is apt to bouts of trepidation when assailed, often neglecting to adhere to his safety protocols due to the hysteria induced by malignant robots.
Nevertheless, while he is relatively impartial in his administration, frequently assigning detention to reprobates, he has a particular disdain for tour renegades and tattletales, as elucidated in "Randy Cunningham: 13th Century Ninja". However, his zealous enforcement of rules often causes students to perceive him as an imperious disciplinarian.
Furthermore, Slimovitz cherishes a vehement adoration for the Whoopee World mascot, Whoopee, and much like Randy and Howard, he surmises that Whoopee is a sentient entity.
However, his fiscal management skills are sub-optimal, often prioritizing his interests over those of his students, evident when he opts to disband the Norrisville High Twirl Team to subsidize cafeteria refurbishments despite the availability of alternative solutions.
Possessions
Slimovitz's Car
Principal Slimovitz venerates his car (resembling an amalgam of models from 1976-1980 of the Plymouth Volare Wagon with beige paint and wood paneling), often prioritizing its robustness over the school’s welfare. Nonetheless, despite its recurring accosts with obliteration at the hands of monsters, robots, or even teachers, his car manages to recuperate after each episode, only, subsequently, to reface imminent destruction, yet such forsakes Slimovitz in a state of tribulation.
