(Firstly, I want to say that, same with Nathan, pardon me for the way that I created this, but I really had no other option because I cannot draw. Another thing is that Maxwell, in reality, has much more muscle than this male Trainer model would let me work with. He is much more of a bodybuilder than this picture lets on. Let's just say that he would fit right in as an ace quarterback or something).

Maxwell Graves was always the "cool kid" in his childhood- he had the strongest legs, the larger muscles, and the most charisma. However, he could not let his "power" go to his head, as his level headed friend, Nathan, would always provide a solution to his problems. Unfortunately, one day, when Nathan began to study his true passion, the bonds that people and Pokémon form, Maxwell became disinterested with him, and he, once again, began competing for the "top spot" of his class. However, Nathan's brainpower was always one step ahead of him. Thus, at the request of his teachers at Pokemon Tech, he began to study Biology and became infatuated with tearing things apart. Then, when a freak accident causes him to lose the Shaymin that he had worked so hard to catch, he blamed Nathan and began to hate him more and more. The gears of revenge in Maxwell's mind never really did leave him, however, and it became a part of his abrasive personality. His Dragonite, unfortunately, also adopts the same personality as him, causing it to become enraged quite easily.
