Rubin is a rukaan from a deviantart ARPG called Fields of Valhalla. As such, Rubin operates within the rules of that game. That being said, Rubin is a giant socially-maladjusted nightmare guy whose favorite hobby is killing people and who has exactly two people he's willing to listen to, and everyone else can go fuck themselves and/or die at his feet as far as he cares. His antics were such that they attracted the attention of multiple people more power than he is, and now he's down an eye and he's got magic armor because he kills so much and so effectively. He also shapeshifts into a wolfy sort of form when he gets to fight, which is "often".

In spite of being awful, Rubin does actually get along fine with his friends provided they don't stop him from, like, killing often and regularly. He's fine, he's a bro, he's just also a liar and an asshole and he loves fighting and LOvES killing just so much.

One of the game's starters is his direct parent (this is fairly common for FoV) and I folded that into his Lore^TM by saying that he's estranged from his family after running off because they wouldn't let him go around killing people for fun all the time. Obviously that's not canon to Fields of Valhalla, but if I ever decide to lift him out of it i'll be keeping that lmfao.

He's a weird aro-bi emotionally stunted Mess (affectionate) and i love the he.

Skironir is also a socially maladjusted weirdo loser who thought the idea of quitting his herd and living alone would be SUPER COOL until he met someone who'd tried it. Instead he wound up just aggressively making friends with Rubin, who is not really complaining because he and Rubin are besties lmfao, and sort of forcibly acclimatizing Rubin to one (1) person.

Skironir himself is fiercely loyal and loves his friends, even when they are the most annoying people alive, and he doesn't like when his friends fight very much. That said, he's still a daredevil extremist who loves things like "lying to police officers" and "robbing dragons while they're present". He lives on the edge and only gets to play straight-man because he went out of his way to find the single more insane person alive than he is, and i just think that's great for him. inspirational.

as prey - Bait hunts someone down and shoots them.
pretty little glass squares - Bait follows another oc, Redshift, out of a convenience store because she wants to tear him limb from limb just so badly.
fracture lines and broken glass - The followup to pretty little glass squares, wherein Bait stumbles across Redshift once again many years later and hooks up with him sort-of-not-really consensually out of curiosity.
Optics - Bait and an organic friend attempt to assassinate an IDW-style phase sixer.

Bait is a neutral assassin and hitman for hire not affiliated with the Decepticon-Autobot Civil War in any real form. The closest she gets is doing murder and torture jobs on random people on either side of the conflict. She left Cybertron a good century and a half before Megatron was even built, and she has no real interest in Cybertronian politics as she doesn't consider herself to be one.

On a personal level, she doesn't consider herself to be a cybertronian or really from anywhere. She instantiated as an insecticon with a rotary alt-mode and has been reformatted so many times that even though she's back to that "base" starting point (sort of... she also has a humanoid-looking alt mode added onto the end, making her a triple-changer, just for social lubrication purposes) she looks and is constructed nothing like what she used to be. She's got an increasing-stakes sort of personality and keeps making things more and more intense on herself just for fun, because if she's already done it once at one intensity then she feels like it gets boring, so she's done a lot of really wacky body modifications and integrated forms of weaponry and types of sex and types of murder and so on and so forth, and she's really just here to have fun.

Please refrain from discussing theology in this server. - Redshift, among several others, get into an argument about theology in a large and very busy Discord server.

Transmissions from Cybertron - Redshift is recruited for a mysterious, highly-classified mission on an abandoned planet that slowly turns stranger and stranger; longform horror told through epistolatory format.
Stop going off into trouble. - Redshift and Astrotrain hug and talk after the events of Transmissions from Cybertron

Redshift is a Decepticon non-combatant who is technically associated with Soundwave's information corps. He has a lot of strong political opinions, cares about his friends, and is otherwise a fairly unremarkable little beta cuck soyboy of a Transformer and everyone around him knows it. He gets into arguments on Twitter and Discord and is afraid to square up irl.

there is someone in the archives (not the one you're thinking) - Haven torments Jonny Sims of the Magnus Archives for his own entertainment.

Haven has mind-control powers that work via the medium of speech, as in, he says "jump" and you jump, no asking how high involved. He uses this to ruin people's lives for fun because he enjoys doing that.

He also has an incredible array of Brain Problems on account of being under way more mind control than is literally ever advisable at all times, having five dead people in his brain, and having an absolute truckload of trauma he's never even begun to process.

He's fun. I want to put him in my mouth.
