If it's the latter, this is a stomp of godly proportions against the cartoon side.
Well in one episode of the fairly odd parents, superfriends(Super hero friends) that timmy wished for cannot be affected by magic, simply because of their power.
now imagine if Cosmo and Wanda made Aang immune to magic and with god like powers like the beyonder , lol!
That would be insane!
Also Timmy has the Cirnsom Chin's!
he did it in the mighty mom and dino dad episode
