The Snakey Bunch Band AU: "Cursed Serpents"
Albus Severus Potter: Drummer Scorpius Malfoy: Pianist/Keyboardist Craig Bowker Jr.: Lead Guitarist Melody Fawley: Guitarist and Vocalist Vincent Goyle: Bassist and Vocalist Cereus Greengrass: Lead Vocalist
Albus and Vincent are constantly sending drummer x bassist memes to each other and talking about how they should totally hook up. Fanbase thinks they're actively in a relationship, but they're just fucking weird.
Cereus is usually in a wheelchair on stage so she doesn't have to stand for extended periods of time, and you know damn well she gets hate whenever she DARES to move her legs.
Scorpius and Melody write most of the songs, sometimes with help from Albus, and they also get input from other members when writing songs about things they experienced. Most songs are three part harmonies, but could theoretically be covered by just one person.
Craig puts different pins on his hat for each performance, but there's always a pride flag and a pokemon.
Scorbus don't even bother hiding their relationship, they go out in public, there are songs that are very clearly about them, but Scorbus is not something most of the fanbase has considered. People tend to think it's either Vilbus, Ceralbus and Scorlody if they even consider that any of them are dating. The people who do think it's Scorbus literally know for a fact, Scorbus make Valentine's Day posts, but the rest of the fanbase who do ship are too set on either drummer x bassist or a straight couple that they flat out refuse to believe them.
These guys don't like being shipped, a lot of them find it pretty weird, especially Melody because she's arospec, but it's actually only a pretty small segment of the fanbase that do this to them.
Cereus and Craig are exes and they're shocked no one's figured it out because, again, they're not secretive about it. It's very publicly available knowledge.
Every single band shirt they'd ever sell contains a Medousa head, but she's making different faces depending on the album.
Their first song is called "Runaways" and it's about, you guessed it, running away from home. Their first big hit song is called "Venomous" and it's about being deceived by someone you loved (something that most of these characters can canonically relate to) using the metaphor of the Medousa myth. The love song that's one hundred percent about Scorbus is called "Eternal Palace" and the reason people think it's Ceralbus is because Cereus is the lead singer, so she's the one singing it, but like, to people who know them and know that Scorpius wrote it, it's so fucking obvious.
Obviously they're alt-rock and I refuse to believe this group of queer disabled kids with Parental Problems(TM) would do any other genre. This is a band containing Albus Potter and Scorpius Malfoy, it was always going to be alternative.
And that's all I can think of for the moment.
