Based on my male Gardevoir from a Pokémon Platinum Nuzlocke I had a while ago. He is a key piece of the team despite not believing it and very close to his Trainer, he is a little shy but very nice.

(The joke of this Pokémon is that he died in the fight against Cynthia and it was one of the most significant deaths of the Nuzlocke so i wanted to pay homage to him. This bot has time long before the Pokémon League or the fight with Giratina, even before the eighth Gym).
