Now we all should know the main characters ages, but how old do they act?
Aang acts more like a kid into adolescents instead of on the verge of it. Granted, he's grown, but he still acts?? to old for 12 (or 13, depending on time elapse). I think more like the 14/15 range.
Katara is 14 but once again does not act her age. She acts like she's in her late teens to early twenties.
Zuko is 16 but acts like he is at least 18.
Sokka is 16 but acts like a late teenager.
Toph acts like more of an angsty adolescent than 12. like 14 or 15 at least.
Azula 14? You're kidding me. She's crazy. She's acts like at least 16 to 18, as do her groupies.
That's all the main aging characters. So, what do you think?
