Character refs are provided in order of setting/species. Things I've drawn before of said characters are always fair game too. In generally, just as long as characters aren't acting hugely out of character, I'm probably gonna be cool with it. I've included a brief note on their personalities if it helps. Post includes a mix of SFW and NSFW references.
Pivot From: PV02
NSFW: okay, though keep it fairly vanilla
Personality: tomboyish, brash, confident, but will do the right thing when it comes down to it. Refuses to give up in a fight.
Socket From: PV02
NSFW: okay, keep it vanilla. Lesbian only.
Personality: empathetic, flowery, anxious / doubts self, good with people. Proud of her appearance and likes showing off
Flux From: PV02
NSFW: okay
Personality: sophisticated, very confident, efficient, and dangerous. Will do things not just efficiently, but with style and flare, just to demonstrate her mastery. Blunt and a bit egotistical, but with the skills to back it up, so her advice is helpful even if it's not what you wish to hear. Has a bit of a French accent for some reason.
Relay From: PV02
NSFW: okay, see below
Personality: very rules-oriented, does things right or not at all, is a stick in the mud at times (though admittedly for good reasons). Takes her job very seriously.
(Non canon) Sexy Relay
The joke lore is that she moonlights as a model on Onlybots, using an alternate chassis.
Pulse From: extended sci fi setting
NSFW: absolutely, no restrictions
Personality: confident, very intelligent, good bedside manner (in multiple ways), horny but like in a tactful way
Bit From: extended sci fi setting
NSFW: absolutely, no restrictions
Personality: brat, overconfident, very dumb, very crude and horny, constantly tries gimmicks in her streams (horny or otherwise) and gets her Onlybots and Twitch mixed up sometimes
Click From: extended sci fi setting
NSFW: absolutely, no restrictions
Personality: asshole, brat, goading, rude, horny
Fuyumi From: fantasy setting and fantasy setting modern time
NSFW: absolutely, no restrictions
she has a small butt but lacks control over her shapeshifting. Third parties have more control over her shapeshifting than she does.
Personality: a bit shy but not really over her figure, cuddly, submissive, a people pleaser
