Ok, so this one... I've had for a while-
But, I've just never shared him with you guys, so now I think I'm going to. (He has alternate versions of himself in different realities-)
Appearance:

His name is Casey Charlton. Him and his family live in rural England. He is super rich (idk how rich-). He (currently) owns 40% of his family's money. Him and his family (The Charltons) are incredibly famous. He is currently 14, and has a twin called Sammy Charlton (DaniellaHallow 's OC). He is one minuete younger than Sammy. He is autistic and Gay (Obviously, 🌈 🏳️‍🌈). He is extremely impatient and a chatterbox. He's scared of and hates the dark, therefore he has a machine in his bedroom that lights up the whole room with cyan waves of light on the ceiling. Sammy knows Casey is Gay. He came out to him and his parents not too long ago. One day, he came out to his little 4 year old sister: Peachy. This was not too long ago. Both Peachy and Sammy accept this, and are proud of Casey.

Casey had nicknamed his sister: Waffle, because she waffles on too much- (Ba dum ching 🔔). He has nickname his twin: Twinie, because him and Casey are twins- (Ba dum ching 🔔).

He currently has a crush on his best friend, Caylus Trotone. Who he met at a park.

He lives in Charlton Manor. Their parents abandoned them recently. An unknown stranger is sending them groceries every week. The Manor is full of staff, who Casey is very familiar with. (E.G: Cassie, Ryan, Hallie, Josef, Kiean.)

Casey's autismn: Casey is socially dumb, and can't read a room or situation very well, he can't read social cues or signals, so he is extremely guilible. He has poor temper control and anger issues, and because he's a teenager it's worse. This anger normally leads to a meltdown, where he will roll around on the floor, screaming and crying and either saying stuff or whispering stuff: "I'll just die then. Yeah, yeah. U clearly don't care about me, hahahahaha! Bye bye, nooooooo!" And, when he reaches his emotional limit he passes out because of it. (This has happened multiple times-)

He has an adorable American bull dog×staffy puppy, Sparky.
Appearance:

(Sparky lore is a whole other rabbit hole-)

This is how Casey would describe himself

Casey: I am funny, and attractive, and amazing. I'm also autistic and impatient. I'm 14 and twins with Sammy Charlton, and brother to Peachy Charlton. I'm a closeted Gay to the public. I'm quite rich and very famous. A car company called Esperage wants me and anyone to do with the Charltons dead. My pronouns are he/him. I try to be polite, but I have anger issues and get annoyed easily. Me and Sammy inherited our father's strength, and good looks.

He's semi-intelligent, and extroverted.

(If you have any more questions about him, or if you want Sparky lore, let me know-)
