In one scene, Romeo (as Captain Smarty Pants) said "It's time to be a hero", but he only proclaimed that phrase in the French dub of the show, as it is replaced with "Okay super buddy, let's take these villains down!" in the English dub.
Also in the English dub, no one says "Time to be a hero" or "It's time to be a hero" for the fourth time.
Catboy and Owlette are brainwashed and turned into villains with the names "Night Panther" and "Dark Owl" by Romeo with his Opposite Ray. In the French version, however, their names were "Tigre Noir" (Black Tiger) and "Merlette" (Black Bird Owl).
Dark Owl is a reference to a villain named Dark Owl in the show Miraculous: Tales of Ladybug and Chat Noir, specifically in the episode named "The Dark Owl."
Miraculous: Tales of Ladybug and Cat Noir was another show that aired on Disney Channel and still does in the US as of 2019.
Romeo is also brainwashed and turned into a good guy with the name "Captain Smarty Pants" by Gekko when he used his Super Gekko Shield to block the ray's blast. Like Night Panther and Dark Owl's names being changed in the French version of the episode, he is known as "Capitaine Super-Malice" (Captain Super Malice).
Although Catboy and Owlette are corrupted into "Night Panther" and "Dark Owl", they are still referred to by their normal nighttime alter-ego names at least twice (three times in the French dub) by Gekko until Romeo is brainwashed and turned into a good guy. While "Captain Smarty Pants" is referred to by his villain name by Owlette when Robot turned him back into Romeo.
This is the fifth time the PJ Masks don't transform back after chanting their victory.
