Both characters here are OCs submitted to me so it only seemed fair to put them against each other. You'll have to go off of what little info you're getting and pure vibes.

Positronic is from an au of roblox game PHIGHTING! that submitter and their friend made. I'm not sure if the art is theirs or a submission.

Zanax is the submitters bee bard DnD character from a current campign. art is by the submitter from what I can tell.

For Zanax he came with a 2309 word backstory /recap of the campaign and I have tried my best to compress it into a few bullet points apolgies to the submitter for butchering hym.

Without further ado, PROPAGANDA BELOW!

Meet Eda!

Meet Eda! She is my main PC for the roleplay multiplayer Space Station 13! Eda can't remember her origins when she was found by a kind old man, he teaches Eda the basics of surviving in the wilds before deciding it would be better for her to stay at the local station. There she has quite a few misadventures, some leading to severe damage of her frail porcelain body, however she stays cheery, even ending up getting adopted by the xenobotanist Teq, who enrolls her in school. All art made in the collage was made in March 2023. Eda was designed by myself. Want to see more of Eda? Check out her Toyhou.se!

Klingons take showers, but they sometimes have to bathe in a wormy ooze. They have this species of worms that helps them exfoliate their skin so kind of like a symbiotic relationship of sorts and they kind of have to stay in that ooze for alteast to 30 minutes to an hour. Maybe more. The smell is a combination of Klingon roses and some bad smell that the worms give off. They have a flehmen response to the smell as well so if any non Klingon sees all this its best to be on their way because non klingons can't get them out of that ooze for any reason. 

Any positronic Android has to bathe in some really disgusting oozey fluid that's good for their bodies and also their bioplasts. It also helps to exfoliate their skin. This all stems from 2 types of silkweed flower which are both a weird combination of a rose like pod like flower and mushrooms which exists as a symbiotic relationship. There are also insects, called Alagos Aphid. This insect is naturally drawn to 2 of the silkweed flowers, it also produces a special type of saliva and feces which mixes with the oil. All in all if the fluid has not been changed or the ribosome or whatever, the smell of the fluid will elicit a strong arousal out of Data or any other positronic Android. Once when Data was on an away team to find more of these plants, one of the ensigns poked it and Data was struggling to not be aroused.
