Another background character could also be Star's brother, as well as Blond Goth David. @monotype-on-phantom had nicknamed one Johnny Test. A short boy with spiky blond hair and green eyes, he screamed at Jazz in Brothers Keeper and about the ghost hornet and threw himself into a locker, crushing his own leg. They headcannoned that the boy is Star's younger brother, super smart like Star is, smart enough to skip ahead a few years, but unlike Star he is a total spazz (and that Lance Thunder, the meteorologist and Ghost Watch reporter, is her dad, making her Star Thunder). It must take a great deal of effort on Star's part to remain popular when her older and younger brothers are very much not. Being dedicated to whatever you deem important could be a family trait, be it being very goth or socially attuned or academic.
ooh I was already super on board with Star being Lance Thunder's kid and I've been running with that with David and his now twin brother Dwayne
but I like the idea about the other kid! I think I know the one you mean, the little spiky blond haired kid that shows up quite a few times in the background (I never realised but he really does look like Johnny Test pffffttt)
I actually really dig the idea that Star's youngest brother is a complete nerd, and her older brothers are weirdo goths, and she's in the centre trying to maintain her popularity
following the Lost Boys theme I've had going with the names, I propose the younger brother be named Marko
