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: The Golden Disc that Megatron stole from Cybertron is the same disc placed on the Voyager spacecraft.

Trivia: Depth Charge is said to have been the only survivor of Colony Omicron after it was destroyed by Rampage. Omicron is also the name of a colony in Star Trek: The Next Generation. It, too, was destroyed leaving only one survivor, Data.
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.
