Show me Servant/Butler/Slave OC

I’ve got two!

Ume was literally created to serve a high-class family, but actually currently serves an unrelated master due to circumstances.  He’ll pretty much do anything this person asks, helped by the fact that he also has a huge crush on the guy.

Endrit is a dragon-man who was found by hunters when he was little, who sold him off to a rich family while he still appeared to be a wyvern. He’s pretty much served rich mages his entire life, over thousands of years, but his loyalty is largely because he knows little else.

Ooh ooh I have a butler over here!
This is Heath, a loyal servant of a demi-god couple (Sebastian & Desdemona)

You can read all about him here to answer most of your questions, but as for if he'd be willing to do anything for his masters? Yes. Yes he would. He's loyal and he considers them friends (if not family) and will do anything in his power to protect them.

Putting under a spoiler bc it's a bit dark.

meet rena ! a very hard working maid who can 10/10 pick up someone two feet taller than her c: anyone can hire her but she's currently looking for an exclusive master/mistress to serve. she's also a cow kemonomimi 

I havent touched this dude in a while but I’m tempted to try and draw him more since he’s fun to draw

hes an undead guard that serves an undead leader. His name is 0003 because he was the 3rd guard created by Crimson, his leader. He’s extremely precious to the undead side of his world because he used to take part in a big war against another side of the world of Oraclis (the world of the story he’s in). hes mostly a background character so he doesn’t appear often in the story. Hes mostly pretty serious and will kill however disobeys his leader or trespasses the undead part of Oraclis. It’s best not to bug or talk to him 

He's the head butler for one of my king OCs. He's always quiet and doesn't show emotion, just cleaning everywhere. He's really quiet, though, so he accidentally sneaks up and scares everyone.

People call him a roomba and he doesn't like it   

Aqua! I just got him so he doesn’t have everything up yet but he’s the consort of an Emperor and is desperately trying to leave and go back home to his family. Dumb Emperor keeps treating him well though so that plan isn’t working out too well.

I've got Minato! He's not willingly a servant. He was a powerful youkai that got tricked into servitude to a devious master. Over time he's shifted from prideful and arrogant to more demure and servile, but he uses the "perfect and polite butler" persona like a knife to passive-aggressively dig at everyone, haha...

rue is a homunculus created by an alchemist who existed in his servitude for upwards of a thousand years. it was what she was created for and what all her instincts are still geared towards so it's really all she knows; she never considered having any other options or even her own personhood? and then something went wrong and the "immortal" alchemist died and she's just sort of been left on her own to figure it out. she isn't a slave anymore but she has so little concept of herself as someone with thoughts and feelings, and is still grappling with how inherently fucked up  being created to be a slave is, and in part because of that she's primarily dedicated herself to continuing her late master's studies.

i haven't really done much w/ him and my ideas are all still muddy but,, without ever reading or watching black butler and only knowing the general plot, my general idea for him is pretty much the same thing jkdhsd but he's generally a refined gentleman, and likes to play some light jokes/ pranks lol

i just gotta draw and design his love interest/ master since i'm a SUCKER for this kind of trope lmao

Got a couple, but they're either WIP or not posted yet

alphonse here is  the princess' butler and doubles as her weapon being a shapeshifting scythe
