Rogercop is a pun on Robocop
While describing his job, Tom says that he once made an Eiffel Tower cake. This is likely a reference to the cake that he made in the episode Timebreaker (2015).
In the French Dub, Roger is promoted to "Brigadier".
When Cat Noir says he and Ladybug should defend themselves in a court of law, he makes a very similar pose to that of Phoenix Wright of the game Phoenix Wright: Ace Attorney (2001), where he points his finger forward and shouts, "Objection!".
