As is made obvious by this episode, Allen is a ufologist, a person who scientifically attempts to study and search for evidence of reports of UFOs and alien visitation. I figured, what better way to introduce a ufologist character than an episode based around a good old-fashioned alien/UFO/men in black story? The story wasn’t based off of any single story, though the ending was heavily inspired by the movie Close Encounters of the Third Kind. Butch and Cassidy played the part of the men in black, shady figures dressed entirely in black who reportedly appear to people who claim to have seen UFOs/aliens in order to intimidate them into not telling anyone else of their experience. Fun fact, Team Interplanetary is also based off of the men in black.
Of important note in the episode is the two new Pokémon introduced in this episode, Eatyai and Yuifoe. For those who didn’t know, the names of Elgyem and Beheeyem are meant to be pronounced as one would pronounce the letters LGM and BEM. LGM stands for little green men, as in the classic term for the stereotypical alien, while BEM stands for bug-eyed monster, an old sci-fi term for aliens with big bug eyes. Both Eatyai and Yuifoe are meant to invoke this same naming pattern. Eatyai is meant to be pronounced something like ETI, which stands for extraterrestrial intelligence, as seen in SETI, the Search for Extraterrestrial Intelligence. Yuifoe is probably obvious, but it’s a spelling of UFO for unidentified flying object.
Speaking of SETI, that’s obviously what I based SETP off of in the episode. It’s a program that uses radio telescopes to search the skies for signals from alien worlds. The name Allen is a double pun. On one hand, it sounds like alien, but the other part is that one of SETI’s major telescope arrays is known as the Allen Telescope Array.
