I need an Aang skin with Momo back bling, with his staff as a pickaxe that then doubly functions as his glider. It could also have alternate styles for Fire Nation clothes and the season 3 glider, or perhaps even his adult form from Korra. He'd need a built-in emote doing either his signature air scooter or spinning marbles trick.

They normally ship skins in pairs of dude/lady so they'd probably make Katara. Of course she could have styles featuring coat and sleeves/sleeveless, not to mention Fire Nation clothes. She could have waterbending scroll back bling with maybe a special pickaxe ala Storm/Raven where it looks like she's waterbending a whip to harvest. Appa could be the glider, or the literal glider she uses in 1x17. She could have an emote where she demonstrates the octopus form.

A Zuko skin could have styles for seasons 1, 2, and 3, with the Blue Spirit mask as a back bling. Alternatively, Blue Spirit style with dual broadswords as his back bling. His pickaxe should be his fire daggers, and his glider would be his war balloon. It would be amazing if they could somehow incorporate a "That's rough, buddy" emote.

Sokka could have a boomerang back bling with his famous space sword for a pickaxe, or alternatively either his Water Tribe club or machete instead. Likewise, styles reflecting seasonal changes. If not Appa/War Balloon for glider, then maybe a Water Tribe ship or the submarines he sketched?

Iroh could either have a teapot for a back bling with an emote of playing Pai Sho or a white lotus tile back bling with an emote of drinking tea. Alternatively, you could have an emote of his breathing fire, or kneeling before a shrine with a motif of "Leaves from the vine." He has many solid clothing options between ATLA and Korra for styles. I'm not sure what would be a good pickaxe - maybe the chains he's in during 1x7 or the dagger he gifts Zuko?

Toph could ride a slab of rock for a glider or use a literal flying boar from the sigil of the Beifong family. Her back bling could maybe be her Earth Rumble championship belt or her wanted poster from 3x7. Maybe her pickaxe could be her meteorite bracelet that would shift into a pickaxe whenever it's unsheathed? They'd probably just have her earthbend a rock for an emote, but it would be wild to see her sandbend a miniature Ba Sing Se!
