SUNNY looks like an average teenager. He has straight, black, ear-length hair with double parted bangs and a triangle bang that slightly drapes between his eyes, with hair antennae resembling a waterspout. He also has arched eyebrows and eyes with the same shade of black, in contrast with his paler skin. Sunny wears a white-collared t-shirt with a black sweater vest over it, beige shorts, white crew-length socks, and black shoes. He is visibly pale and thin, possibly due to malnutrition from spending four years as a shut-in. He is 5’5 and sixteen.

In the REAL WORLD, KEL appears as an older teenager. He has grown much taller than most of his friends. Like his brother HERO, KEL has brown hair and naturally tan skin. He also has a well-built body due to constantly playing basketball. His main attire consists of an orange basketball uniform with white stripes and a center design that resembles a dog. He is 6’0 and sixteen years old.
