Tristan Elur'on would play an archer of Shevarash, because he views them as heroes and really fanboys over them, therefore he'd use the opportunity to live out his fantasy in a game of DnD.

If a kid could be a fan of Batman, then well... They're like his "Batman."

Gekido would play a paladin but would still be an incredibly aggressive murderhobo

None of my characters would waste time playing silly games.
..Except maybe Wheua.

Khara'gos would pick whatever is the most optimal.
Drad would probably pick a weird little guy, maybe a Goblin Shaman, and do weird little guy stuff.
Twang would eat the pieces.

Salasker would diligently collect all the books, modules, magazines, and third party add-ons, then read them constantly without ever actually playing the game.

Drext would play a Divine Champion of Oberon.

Byrny would play a half-orc Paladin of Sune, for sure... Because she likes the odd ducks.

Well. Viridovix would try to roleplay a noble, or a 'jarl' of his people, a warlord or something. Definetely Fighter...if 4e, Warlord!

Ymmstrid would totally play a Commoner and try to become the wealthiest person alive

Yuanjun would play Zayd Bashir (here).

Imagia would almost certainly play a Ranger.

Iosefka would play a hyper-competent Artificer, and consistently fails at being smart enough to play her character.

Liv would almost certainly play some kind of cavalier build, idk.
