Gladion

Gladion has a very serious, determined, and smart disposition. He is shown to be very strong willed, as he constantly strives to make his Pokémon strong no matter what. Gladion can be impatient, temperamental, and frequently gets annoyed by Hau's excitable and fun-loving nature. He also seems to be quite self-critical, as seen when he loses a battle. Although he appears to have a tough exterior, it is eventually revealed that he is actually quite caring and always thinks of the well-being of Pokémon, and he cares about his sister Lillie deeply as well. He also cares for his Pokémon Type: Null, whom he rescued from the Aether Foundation and sought to free it from its metal restraint.
