Scarlet Moth’s outfit is the same as Hawk Moth's except it is colored strong crimson due to the enhancement from Catalyst. His mask, cane, and the Butterfly Miraculous are also colored the same red. His cane allows him to create more than one akuma, giving him an advantage.
Shadow Moth's outfit is the same as Hawk Moth's except he now owns a blue tailcoat with the tail possessing a number of rounded points with indigo, dark-purple-centered spots, resembling a peacock's tail feathers. The lapel of that tailcoat makes a large collar that's wider at the back and he wears a peacock-feather-like cocktail mask which is indigo and tear-shaped with a darker purple mark in the center and a brilliant crimson translucent eyehole over his right eye. In his Shadow Moth form, the Peacock Miraculous is being placed below where the Butterfly Miraculous brooch is.
Hawk Moth has white hair and white eyes, and he doesn't wear a mask over his face. He wears a white dress suit with a pale tan vest and bow.
