...Different Destinations - S3-E5
Trivia: While they're waiting for the Venek Horde to attack again, when John's chained to the statue Scorpius/Harvey's playing the harmonica with his feet up on John's lap. Notice that both soles of Scorpius/Harvey's red boots have the name "Andy" written on them. In "Toy Story" Woody's boot has "Andy" written on its sole, and here in John's mind it's to signify John's ownership of the neural clone.
The Scorn of the Star Sapphire! - S3-E5
Trivia: After freeing Miss Taylor from the grip of Star Sapphire, Green Lantern encases her in a green energy box and flies her away. The box is shaped almost exactly like a shuttle craft from Star Trek. (00:15:50)
Trivia: In this incredibly stupid NBC television sitcom that lasted only one season (from Sept. 1965 to April 1966), Jerry Van Dyke's late mother is reincarnated as a hideous vintage ragtop jalopy called a "1928 Porter"; but, in fact, no such vehicle was ever produced in automotive history. The 1928 Porter was a fantasy car assembled strictly for this short-lived TV show, using bits and pieces of a Model-T Ford, a Maxwell, a Hudson, and a Chevrolet.
Superskrull - S1-E7
Trivia: The Godzilla parody movie that the Skulls are watching at the beginning of the episode says it is presented by Roger Shnorman. This is a reference to cult-film director Roger Corman, who himself was an executive producer on a Fantastic Four film that was made around the same time this series aired, but was deliberately never released.

Trivia: Walter Jones (Zack the Black Ranger) is missing his left middle finger. If you look closely you'll see it missing at various times throughout the show. Particularly when he morphs (he's the only one that only has three fingers on top of the morpher).
Trivia: At the beginning of the scene where Clara persuades Rigsy to give her his chronolock, a poster can be seen on a wall in the background, reading "DeLorean" (a Back to the Future reference) in Aurebesh (the writing system from Star Wars). (00:25:00)
Trivia: One of the images in Gambit's mind-scan is of fellow Marvel Comics superhero Ghost Rider. (00:07:45)

Trivia: The 'dialysis machine' which Molly obtains from the GSC to use on her son is actually an Apple AirPort Extreme Wireless Router turned upside-down. (00:32:00)
Trivia: Stan Lee has a cameo in this episode as the man having his shoes polished next to Stark and Jarvis.
