I mean, I have a couple I might as well introduce because they haven't threaded much.
Tessa: Profoundly amoral, blonde. Scientific mindset, though she's more about results than process; she could make it in Materia fine. (Better than fine, really. She'd fucking love it.) Her mother generally dies in childbirth even when this is hilariously implausible, and she kills her father around age 13 because he's neglectful and depressive and unworthy of her existence. Actually gets along pretty well with Ari a lot of the time, even though she kind of reminds him of his mom; often willing to do productive things and become a perfectly functional member of society; feels an incredibly intense lust/hate towards Zanns, or just hate if it's a Xan. (She's a demisexual lesbian with obsessive tendencies, label-wise.) Account can be found

Anya: Anya from Buffy. Intensely awkward, with no native moral compass but a moderate desire to make a subset of people happy; tendency to be nonhuman. Thoroughly metacausally linked to Harry, for reasons unknown to anyone including myself. Terrifying in combat, well-versed in any magics locally available, and extraordinarily plucky.

Sky, Hakim, Rowan: Trio of protagonists from original novel in progress and not slated to be completed at any point in the foreseeable or for that matter unforeseen future. Sky is agender (they/it), Hakim is a dude, Rowan is a chick to whatever degree Rowan can be classified as anything. Sky has a tendency to grow wings and heal people; Hakim is irritable and makes mad science/magic trinkets and he's kind of in love with Sky; Rowan has a disconcerting habit of shapeshifting while talking to you and is cheerfully morally ambiguous. They have misadventures in the B-plot of everything.
Zafira: A skeletally thin and generally discomfiting young woman with a heart of gold... probably. She believes thoroughly in the power of friendship, love, and all that anime shit. She's also got a knack for saying exactly what she needs to say, and for playing everyone it takes to get the job done. She's not on any side but her own, but if you're on her side she'll move heaven and earth to help you out. Just make sure not to get in her way. (Or that of any of her seven significant others.)
Alain: A beautiful young man, apart from the fact that approximately every inch of his body is covered in scars. He's intensely paranoid and fatalistic due to what could be termed an "unstable home environment," and definitely does not believe in the power of friendship, love, or any other such anime shit. What he does believe is that he can save the world from whatever it needs saving from, and he's the only one who can do it right. Him and his substantial collection of knives. He's got some immediately obvious problems with intimacy, but if he and Zafira coexist in a universe, they're extremely close friends despite the fact that there's absolutely no way they should even be able to tolerate each other. Such is the magic of friendship, in which, to reiterate, Alain does not believe.
Elisha: Distinctly underdeveloped template-cousin and/or uncomfortably flirtatious brother of Ari. Strongly resembles Ari, but with a little more Belinda and a little less Golden Retriever. He's still happy, and he's still more or less a good person, but Ari's cheerful ignorance of conventional morality is replaced with a disdain towards it. Devoted to personal freedoms over maximal utility, which isn't a sin in moderation, but in excess starts to get a little bit uncomfortable. Bears the face of Kevin Warhol, as I am weak.
