Role in the film
Elmo is a middle-aged repairman who makes a living repairing old appliances or disassembling them to sell for profit. Therefore, he is feared by all who are sent to his shop. Also, when appliances try to hide from him to avoid being officially disassembled and sold when customers arrive at his shop, he easily locates them. Radio informs the other appliances that Elmo seems like a nice enough fellow, which describes that he is their new master, but then what Elmo did to Blender made them find out that he is cruel towards them, which describes that Toaster and his gang do not need a new master after all (although one must note he does not know that they are alive).
Elmo shows up in the swamp where Toaster and his gang nearly drown and rescues them from a cruel fate, he discovers the appliances when he hears the radio playing a song. He then loads them in his monster truck and takes them to his store, intending on either selling them or disassembling them for parts if necessary for his customers.
That day, a man named Zeke requests a replacement blender motor for his wife. As a suave salesman, Elmo lies to him saying he has a new shipment of blenders, but in reality, only had one from his working blender. Blender desperately tries to hide but is discovered and disassembled in a manner similar to a surgery scene of a horror film. Upon the removal of his motor, Blender apparently dies and Elmo sells off his next product. Zeke then returns and requests some radio tubes, also for his wife, with Radio only being available to provide such parts. The gang tries to hide him, but he is discovered as well. Lampy then forms a plan to save their friend.
Just as Elmo prepares to disassemble Radio, Toaster draws the curtains and plants himself on top of Kirby with Blanky on his head, approaching Elmo like a ghost. Elmo sees his reflection in Toaster's metal plating and screams in terror, running around the storage room until he smashes into a pole, knocking him out unconscious. The appliances then all escape to who-knows-where, wrecking Elmo's store in the process. By the time he comes to, he has no idea what had happened, but his customer pops in, still requesting the unavailable radio tubes. Elmo's business probably suffered as a result of the appliances escaping. He isn't seen again for the rest of the film.
- Elmo St. Peters shares some similarities with Sid Phillips from Toy Story (It is likely Sid was inspired from Elmo St. Peters):
- They often rip objects apart or reassemble them in an awkward manner, making them a villain to said objects.
- They own a lot of objects that are mutated as a result of being ripped apart or reassembled.
- They end up being scared out of their wits by the objects who come to life in their presence, and both cases involve said objects rescuing a friend from suffering a terrible fate.
- His name is a reference to St. Peter, the gatekeeper of Heaven. This is likely an allusion to the fact that both are symbolic of the afterlife, as Elmo's shop is the final resting place for some appliances.
- He seems to dislike the environment, as he destroyed a couple of trees on his way back to his store.
- In the novella by Thomas M. Disch, he is inspired by the villain who is referred to as "The Pirate", who works in a dump and is frightened by the appliances in the same way to save Radio.
