Maang
A love triangle that never ends. Meng is head-over-heels for Aang, but Aang is too busy drooling over Katara to notice. Meng is so mad, she might slap the next person who says Katara is 'cute'.
'Meng is like a dog who got left at the door while Aang ran off with the mailman.'
'If Aang doesn't pick Katara, Meng is gonna turn into a firebender and burn the entire team.'
'Meng is the only one who remembers Aang was an airbender before he became a love-sick idiot.'
