Gallade Erureido

Gallade Erureido is a student at Pokemon Highschool and a member of Team Psychic. He was introduced as an antgonist when he served under Frosslass, aiding her in her plans of unlocking the seal of Dawn Shrine. After the events, he still showed some loyalty to her and went through an odd sex change. His boyfriend is Frealigatr Ordairu.

Trivia

 * A running gag throughout the series is that the Psychic and Fighting "spirit personas" of Gallade, Ebony and Ivory, residing in his swords. Since they are conflicting types, the swords will usually draw themselves out and fight with each other or do so in their spirit forms, much to Gallade's chagrin.
 * Gallade is the only character so far that has been through a sex change and has stayed with alternating between the two.
 * Gallade does swordsmanship practice with Garchomp, putting them on friendly terms. This may be because they are Sinnoh Pokemon.
 * Gallade, despite his typing (Psychic/Fighting), he used to serve faithfully under Froslass (Ice/Ghost) ironically. This relation may be due to them being Sinnoh Pokemon.
 * Some people mistaked Gallade for being an unintelligent, bulky person since he is more known for his Fighting-typing than he is his Psychic-typing.
