Trivia: The three Predacons who make up the Tripredacus Council are supposed to be Cicadacon, Ram Horn, and Sea Clamp, the three characters that combine to form the Beast Wars action figure Tripredacus. It was production company Mainframe's intention to make its show counterparts resemble its respective action figures, but there wasn't time to fully design them. This is also why the character designs look "simple" in comparison to other characters on the show.
Trivia: In the Season 3 episode "Feral Scream, Part 2," Optimus calls Depth Charge a "hardhead." Hardhead was an Autobot who appeared in the Transformers: Headmasters comic. Coincidentally, part of Hardhead's file reads: "The only way to get Hardhead to follow advice is to persuade him he came up with the idea himself. He knows only one way to do anything - his way." Sounds a lot like Depth Charge's mentality to me.
Trivia: In Dinobot's quarters, after thinking about committing suicide, he looks out the window and sees three birds fly past. They're flying the "missing man" formation, which is also performed by Silverbolt, Optimus, and Cheetor at the end of the episode to honor the fallen Dinobot.
Trivia: In the episode where Starscream (a Generation 1 character) possesses Waspinator, they could not use Starscream's original voice actor(Chris Latta), because he had unfortunately passed away several years prior. So they used the voice actor for Terrorsaur. Also, because the actor's impression of Starscream and Terrorsaur is so alike, Terrorsaur has very few lines in the episode.
Trivia: The Golden Disc that Megatron stole from Cybertron is the same disc placed on the Voyager spacecraft. You can even see the words "Sounds of Earth" printed on it several times across the series. You can check out what the disc actually looks like here: http://www.solarviews.com/cap/craft/sounds.htm.
Trivia: Tigatron and Black Arachnia weren't supposed to appear in the show originally, and so their action figures were just repaints of Cheetor and Tarantulas, respectively. When they were chosen to join the teams (Tigatron in place of Wolfang, Black Arachnia on her own), the animators panicked because they had no body casts to work with, and made up their looks on the fly.
