Aang's Arrow

Bold textIn avatar aang has an arrow on his head, hands and feet. Airbenders who have attained a level of mastery in the art will be marked with arrow tattoos, based on the arrows of the Sky Bison, the first Airbenders. For male Airbenders, a primary arrow tattoo is placed on their shaven head that extends down their back, along with four others, one on each limb that terminates in an arrowhead at the hands or feet. According to the series creators, these arrows mark the paths through which chi travels through the body. When an Avatar tattooed in this fashion enters the Avatar State, these tattoos are known to glow along with the Avatar's eyes and mouth.
