Eyyy finally! God this took a long time XD
Alr, so all of these are AU specific, so don’t come for my ass if you have disagree LOL
Although I would love to hear any of y’all’s LGBT headcannons for the Sonic cast, if you have any, civilly, in the comments :3

Lets get to listing, because some of them it might be hard to tell who’s got what pff

Sonic — Aro/ace
Tails — he has the pride flag, he’s questioning :3
Knuckles — pansexual
Amy — also pansexual
Shadow — Aro/ace and Non-binary
Blaze — Bisexual and Transgender
Silver — Bisexual and Demiboy
Rouge — Omnisexual
Eggman — Gay MLM
Vector — Omnisexual
Espio — Lithosexual and Transgender
Charme — he’s here to support <3
Marine — Pansexual and Genderfluid
Mephiles — Apothosexual and Non-Binary
Metal Sonic doesn’t have his identities, he was just painted to show some other identities :>
-Agender
-Demigirl
-Intersex
-Graysexual
-Fraysexual
-Lesbian
-Polysexual

And that’s it! I have a lot more characters in my AU with a lot more variety, but for my sake it’s just these guys this year XD
Hope y’all like it! Happy pride month!! :DD
