Billy Watson is the main protagonist of Billy 10.
Billy takes the appearance of a teenage boy. He has messy, black hair and green eyes, but he wears a long-sleeved white T-shirt with the number 10 in green. He wears the Omnitrix on his right wrist.
Billy is a brave and smart kid. He will often throw himself into a situation without thinking it through and get stumbled on problems. However, the obvious comes to him eventually and he tends to figure it out. He is also friendly and a big-hearted person, willing to help his loved ones; even his enemies.
In And Then There Were A Heroes, Bart Modell was impressed by his incredible intelligence making Guardiantbots for security measures.
