(Actually yeah, gonna write this up while the mood strikes me:
Bill Cipher: Human, mentally and physically twelve-years-old. Gender is triangle. Basically just canon Bill plopped down into a powerless human body after his death, we know how it goes. Still has all his memories, and is determined to make the Pines family's lives (especially Ford's) a living hell while trying to find a way to get back to full power. Only power he has left at the moment is the inability to stay dead; can respawn back to life in a matter of seconds if he's killed.
I'm on the fence about whether or not this specific Bill has done time in the Theraprism and escaped via their reincarnation machine (I designed him long before TBOB dropped) but I do like the idea a lot and might use it depending on the verse. (Sidenote: Also contains verses where he is a sphynx cat, a Danganronpa verse where his talent is The Ultimate Liar, and any other verses where the mood might strike. Also obviously given his age, I will not write shipping with Ford or any other adults. Probably not any of the kids either, I just have no desire to ship him in general.)
Mina: Human and triangle, able to swap between forms, mentally and physically twelve-years-old. Transfem. Bill's twin from Euclydia, one who somehow survived the destruction by being sealed away in an unknown, inescapable Dream Realm for the trillion years to follow.
Much like her brother, she did not age during her time there and eventually managed to escape. She's not out for revenge or harbors any sort of hatred for Bill, in fact, she is very timid and shy and mostly just a lonely little girl who wants to see her brother again.
(Sidenote: She is the most specialest girl in the world and has done nothing wrong, ever, in her life. Also she's a big fan of a stars and moon aesthetic. And, as you might've guessed, is purple in her triangle form.)
Dev Roswell: Human, thirteen-years-old. He/they, transmasc nonbinary. Dev's big into the supernatural and paranormal, and was created as a best friend to Dipper Pines and a boyfriend/SO to Mabel Pines. They love all things weird and mysterious, although their absolute favorite topic of interest is aliens (he insists that he's kissed one before).
Lives in Piedmont and has never been to Gravity Falls, but is quite the superfan and hopes that his older brother will one day let him join Dipper and Mabel there for their summer trip. In the meantime, all he can do is dream and listen to their stories about the town with all the envy in the world.
(Sidenote: Pre-established relationships don't have to carry over to RPs; they can be developed and changed depending on the AUs).
