Catboy and Owlette are brainwashed and turned into villains with the names "Night Panther" and "Dark Owl" by Romeo with his Opposite Ray.
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.
Although "Night Panther" and "Dark Owl" are created, they are still referred to by their superhero names 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.
