Some of the trainer sprites in Ruby, Sapphire, and Emerald were changed for the international versions. Hex Maniacs were given smaller eyes with pupils, and the female Psychics have their arms outstretched, and the Male Cooltrainer has minor changes to his hairstyle.
The most obvious change is the sailor, whose original pose resembles a gesture called the "Bras d'honneur", involving raising a fist and slapping the biceps on the same arm (also known as the "Iberian slap" or "Iberian finger"), which is seen as an offensive gesture in a number of countries.
