Trivia

 * Although Gardevoir looks feminine, the probability of being male or female is in both cases 50%. That is, between 2 Gardevoirs there may be procreation.
 * From what has been said before, Gallade will never be female (0% probability). Therefore, if Gallade wants to procreate, it will have to look for a female Gardevoir, or with the help of Ditto, which can breed with any species that has an egg group, including males.
 * This is the Pokémon that most fanarts with humanly sexual situations has had so far on the Internet.
 * Although it has human appearance, Gardevoir is not of the group Humanoid egg, but corresponds to the group amorphous egg, with Pokemon without a specific form, something strange.
