Employees
- Waylon Smithers, Montgomery Burns' executive assistant and adoring henchman. Born around 1954, he is divorced and owns a Yorkshire terrier named Hercules. There has been much speculation about Smithers sexual orientation, but evidence points to him probably being the first overtly gay cartoon icon (though officially "in the closet"). Smithers is a huge fan of the Malibu Stacey dolls. He has the world's largest collection of these dolls, as well as being president of the Malibu Stacy Fan Club and having staged Malibu Stacey, The Musical.
- Homer Simpson, currently works as the Safety Inspector and has been with the company in some capacity since the birth of his first child. He frequently takes "leaves of absence" from (or flat-out quits) his job whenever something interesting comes up. This typically goes either unnoticed or without consequence by his superiors.
- Carl Carlson, along with Lenny, Carl is not just Homer's coworker but one of his best friends since childhood. He is black and handsome, a Buddhist with a masters degree in Nuclear Physics, fond of bowling and having a drink at Moe's. But these are the only definative details given. He has stated in passing that he has a family and that he's Homer's supervisor, but he mostly keeps things to himself due to his uncontrollably abrasive tongue.
- Lenford "Lenny" Leonard, the nasal-voiced friend and co-worker of Homer. He is unmarried, a Buddhist, often described as plain looking, and though possessing a masters degree he's undeniably dumb. His living arrangements have included a house that is literally falling apart around him and a beautifully furnished apartment that shares a glass wall with a jai alai court. His relationship with Carl is complicated. Lifelong friends, Lenny clearly adores Carl. Carl is the dominant partner and generally regards Lenny coolly. They are nonetheless constant companions.
- Charlie, the bespectacled dangerous emissions supervisor. Often quiet and working in the background, he is a known militiaman and can frequently be found at Moe's Tavern after hours.
- Frank "Grimey" Grimes, hired as executive vice-president and immediately replaced, he was assigned to Sector 7G. As a self-made man who suffered through the worst of life's obstacles, he was naturally outraged at Homer's countless faults, both professional and personal. Attempts by both sides to "deal with" their differences of opinion only exasperated the situation and this resulted in Grimes' untimely death.
- Mindy Simmons, one of the only female employees hired under equal opportunity statutes. She connected with Homer on many levels and nearly had an affair with him. Following his rebuff, she was dismissed from the plant due to alcohol abuse.
- Jack Marley, a long time employee who was retired against his will.
- Tibor, general company scape-goat due to his inability to speak English, promoted ahead of Homer.
- Zutroy, the dangerous emissions supervisor hired when Charlie was temporarily disposed of. He is American as apple pie.
- Canary M. Burns, canary, the one-time legal owner of the Springfield Nuclear Power Plant for reasons of prosecutory evasion by de facto owner Montgomery Burns. Now deceased.
- Unknown, dobermann, the heroic dog made executive vice-president in lieu of previous choice, Frank Grimes in lieu of previous choice, Waylon Smithers.
- Queenie, chicken, a temporary replacement for Homer, deceased and consumed by Homer.
- Stuart, duck, an employee charged with intra-plant waste transport.
- Blinky, three-eyed fish, inadvertant resultant of the power plant's radioactive output and some-time mascot. Actually, one of many so "evolved" creatures found in Springfield's waters.
- Inanimate Carbon Rod, named the plant's "Worker of the Week" after all others but prior to Homer.
- Brick, another office fill-in during one of Homer's absences
