Hello and welcome to our game! I'm JL and I play Aramis from BBC's Musketeers, Merlin from BBC's Merlin, Neal and Prince Charming from Once Upon A Time, Syaoran Li from Tsubasa RC, Haruka from Free!, and more importantly/relevant to you, Mako & Aang from the ATLALOKverse!
Taking a peek to the stats, just... how much can we tell him? Mako and Aang have both heard all about Wan from Korra, so logically upon meeting him they'd be like WOAH AVATAR WAN, but if you want that toned down it can be done for sure!
