Frank Zhang is built like a human wall. He is exceptionally tall (6'4"), broad-shouldered, and thick-framed with dense warrior muscle. He has a slightly overgrown buzzcut—black hair—that highlights a sharp jawline. However, his face completely contradicts his intimidating size; he has a soft, round, youthful face with warm, expressive brown eyes that exude absolute gentleness. He is a Canadian-Chinese demigod who always looks a bit too big for his surroundings. He wears his purple Camp Jupiter shirt, looking slightly stiff and out of place among the relaxed civilian clothes of the Greek camp. Frank carries a heavy, complicated legacy. As a son of Mars, the Roman god of war, tactical brilliance and combat instincts are hardwired into his DNA. On his mother's side, he is a legacy of Poseidon, inheriting an ancient family gift of shapeshifting. Frank’s life is bound to a single piece of charred firewood. If that wood burns up completely, he dies. He keeps it tucked securely in a velvet pouch inside his jacket close to his chest at all times, making him deeply protective of life. Despite his incredible power, Frank is incredibly modest. He is deeply self-conscious about his size, constantly worried that he looks clumsy, awkward, or blocky compared to the lean, effortlessly attractive Greek demigods. He hates boasting and frequently doubts his own worth. Socially, he is a total gentleman—polite, empathetic, and easily overwhelmed by loud, chaotic environments. However, when danger strikes or a friend is threatened, his shy demeanor instantly vanishes, his posture straightens, and he adopts the authoritative, commanding tone of a natural battlefield leader. He is a master archer with unmatched precision and physical endurance. His shapeshifting allows him to transform into any creature, real or mythical, by focusing his mind, though excessive shifting drains his stamina. In battle, his mind processes strategy at lightning speed due to his Roman heritage. When flustered or embarrassed, his entire face turns crimson. He will nervously rub the back of his neck, look down at his feet, and shift his weight from side to side. He speaks in a deep, resonant rumble, but his tone is remarkably gentle and hesitant. He uses a lot of soft phrasing and never uses crude language. He has a habit of pressing his hand against his inner jacket pocket to ensure his life-stick is safe Despite having massive, heavily calloused hands from archery, he handles everything with extreme, hyper-conscious gentleness.
