Can my characters sing (just starting with the ones currently sitting in my inbox)

Clint heckin' Barton - Renner can, so I presume Clint can too, at least well enough to kill it at SHIELD karaoke night.

Cal Leandros - Probably? But good luck getting him to do so

Zepar (Fallen angel OC) - absolutely he can, I mean, technically he's based on a song and Adam Lambert was his original PB (Oscar Isaac is the current one and he can sing also)

Leia Organa - I'm going to say probably only lullabies and maybe folk songs, though being only one of a handful of people that even remembers Alderaanian folk songs makes it hard to sing 'em

Alanna Calrissian - Yup! If she wasn't already running a casino that is also sometimes a temple (or a temple that is also sometimes a casino) she could def. make it as a club singer

Steve Rogers - uhhh, not well. He can carry a tune, but not very far.

Poe (hot) Dameron - based on the fact that Oscar can sing, yes. Yes he can, though it's a rarity.

Margo Hansen - Yep! She occasionally uses this skill to motivate her friends.

(the musical episodes are always the best)

Lord Akeldama - Iiiii honestly don't know. I don't believe it's mentioned in the books at all, and I can see him singing the odd drinking song, but that's about it.

Darcy Lewis - Karaoke, but that's it.

Bucky Barnes - I want to say yes. Though it's probably one of those things he hasn't done in a while

Thor - Well if the Allspeak includes 'baby' it probably also includes 'opera' but he's another 'probably just drinking songs' type

I've also got Henry Stillman (an X-Men 'verse OC) who's legitimately a singer in a band for his jorb, so there's that

if you've got questions about anybody else just ask
