Brendan from Pokemon Omega Ruby/Alpha Sapphire

A young person dressed in a vibrant red and green costume, reminiscent of a Pokémon trainer's attire. The individual is standing in a lush grassy area, with their right leg bent at the knee and their left arm raised to shoulder height. They wear a black hat adorned with a red and green design, complemented by a matching red and green sash draped across their chest. A white fabric piece is attached to the front of the sash, adding an extra layer of detail to the overall ensemble. The young person's attire is completed by a pair of dark blue shorts, providing a subtle contrast to the bold colors of the rest of the outfit.
