Meelo is one of Tenzin and Pema's 3 children. He is an airbender like the rest of his siblings. He is described to be a fun, easygoing, mischievous and carefree person.
When Meelo and his family travelled to the Southern Water Tribe to pay Korra a visit, Meelo was seen chewing his father's head when they hopped off their sky bison. During airbending training, Meelo usually falls asleep when they meditate.
