they were all born in a sort of bootleg dimension, where it attempts to replicate various IPs, but it's always warped in one way or another. these guys happen to be apart of the sonic land, where sonic bootlegs roam.

there are 14 siblings total, and i will list their names in order from first to last

retro
coffee
blueberry
splendor
envy
lime
lemon
chocolate
lantern
concrete
copper
vanilla
peach
cascade

retro is the oldest of the siblings, and also the self-proclaimed leader. the others don't protest and go along with it for the sake of it

coffee is that one chill person in the friend group. he's always laid back and never takes things too seriously

blueberry is one of the most childish. he happens to be kinda stupid so the others act like caretakers for him

splendor is super edgy and his siblings don't exactly like him for it. he is always distanced from them and is often melodramatic

envy is well, envious. he has a short temper and often is jealous of the others. however, when he's not angry or bitter towards others, he's actually a really nice guy

lime is childlike similarly to blueberry, but unlike him, lime actually is smart. think of him as hard-working student at school

lemon basically works in conjunction with lime. she always tries to help lime out whenever he's in trouble and overall they just like hanging out with each other

chocolate is a very sweet gal. she's always eager to listen to others and never is rude to anyone or anything. tho, the siblings are in on a joke that choc is secretly a serial killer, in which she is aware of this joke and plays along with it

lantern is one of the bravest of the siblings. whenever someone's in trouble, he's usually there to get them outta it. he also happens to be pretty strong, which doesn't exactly show in his appearance

concrete is probably the smartest out of all the siblings, and one of the oldest. he often figures things out for his brothers and sisters alike, and is never unwilling to do something for someone

copper is a scaredy cat. he squeals in fear at the tiniest of scares and overall isn't exactly fun to be around. tho, when he isn't pissing himself, he's kinda sweet. chocolate likes to hangs out with him a lot when she isn't busy with other things

vanilla is similar to chocolate in a way, which in turn immediately made them bestie best best friends. if all of the siblings happen to be grouped up in one area, but vanilla nor choc are there, it is guaranteed they're off doing something with each other

peach is the most mature out of the sisters. she is usually seen telling the others what to do and don't do, acting like a mother figure to the whole group

cascade is the youngest along with blueberry, however he does actually have some intellect, though it is not very visible a lot of the time. you'll usually see him drawing, mostly drawing cascades

one feature that all of the siblings share is that if you tell them about the fact that they live in a bootleg world and that it's not the real deal, they will shatter into a dozen pieces. the only way to make them return to normal is if you pour oil on their remains, which will immediately piece them back together. they will forget that you said anything.
