Trivia: Simon Pegg's extended cameo as Hughie's father is a specific nod to the comics - the look of "Wee Hughie" in the original comics was based on Simon Pegg. Artist Darick Robertson said "it was important to capture an innocence but tough determination in Hughie. Two things that seemed to contradict each other and somehow in early sketches he kept looking too old. When I saw Simon Pegg in Spaced I thought he captured that balance perfectly." Pegg knew he was too old to play the character himself, but was happy to play his father.
Trivia: The animated series featured the first appearance of the Holodeck (called the Rec Room) in this episode only. Gene Roddenberry wanted to use the Rec Room/Holodeck idea in the original live action series of the 1960s, but found that budgetary constraints were prohibitive at that time. The Rec Room finally appeared once in the animated series, in this episode, in 1973. It wouldn't be seen again until Star Trek: The Next Generation, in 1987, some 14 years later.
Trivia: Robert Patrick complains about the rise of the machines and asks who is that gonna be good for? This is an homage to his role in the Terminator 2 Movie as the T-1000.

Clone Cadets - S3-E1
Trivia: Commander Colt watches Domino Squad do their test and says, "Start The Citadel challenge, version THX, variable 1138," which is a reference to THX 1138, another film by George Lucas.
Trivia: This series was roughly halfway through filming its 18 planned episodes when Marvel suddenly scrapped it and decided to start over and have just 9 episodes and hire a showrunner (a first for a Marvel Disney+ series). Reportedly, the original writing had a very legal procedural format, and Matt Murdock didn't even suit up as Daredevil until the 4th episode. In the process of revamping the series, Marvel decided to officially make the original Netflix show canon to the Marvel Cinematic Universe.
Trivia: Kingpin is voiced by Michael Clarke Duncan, who also played him in the live-action 2003 "Daredevil" movie.
Trivia: Almost all of the rock songs in the soundtrack (which are primarily songs Ash listens to on the radio) are from the 1970's and 1980's. This was done on purpose, to help illustrate how Ash has been stuck in a state of emotional arrested development since his original adventures - he hasn't really grown as a person since.
