Fire Starter

Who exactly is the avatar? More importantly, what is he? Well from what I know, the avatar is the human embodiment and incarnation of the 4 main elements of earth: fire, water, earth and air. In simpler words, he is the earth itself manifested in human form... He is able to master all 4 of the elements and use them at will.. The avatar never dies however, as he is constantly reincarnated to a descending generation.. Aang is not of his companions' generation. Katara, 14 and her brother, also in his teens, are pathetically young compared to the 112 year old avatar, who was frozen in an iceberg when he was 12.. He was in suspended animation, or in cryo (I believe the full term is cryostasis) where the human body can neither grow nor deteriorate, leaving it stagnant for future "use"..
