I think there should be some lesbians here on this fine blog. I'm going to submit some Slipstream/Blackarachnia, if you don't mind!
Blackarachnia has an ovipositer. She wants Slipstream - her smart, beautiful, and deadly lover - as the carrier of her eggs. I'm going to say that these are larger, more Cybertronian-sized eggs. Slipstream loves her girlfriend, and is happy to carry her eggs. Slipstream is fed a very decadant fertility aid to help the process flow nice and easy. Blackarachnia gets her seeker nice, happy, and plump enough to grow some eggs. She also makes her and her lover a nice comfy nest, and makes the clones help out too. Slipstream is treated how her creator Starscream always wanted to be.
LESBIANS✊
Eggpreg is so underrated in valveplug stuff imo. Blackarachnia happily filling her beautiful girlfriend til she's nice and round, caring for her in ways Starscream could only dream of. Slipstream is also very pleased with this. She's happy, plump, and full of eggs from her dear girlfriend. She gets extra cuddles as well.
Starscream is definitely the shady lawyer type. Prosecution, probably. I also get the sense he would ride a motorcycle or fancy sports car. Maybe a cybertruck to flaunt his wealth.
I didn't draw the other seekers(because they look exactly like him). And I just never felt like coming up with various similar-but-different human designs for them either.
Slipstream always struck me as being Starscream's ambition in the same way the others represented his various traits. I doubt that was the intention, but it's better than the alternative imo.
Anyway, she seems like the type of person to become a lawyer and oppose Starscream in every case she could. If he's a prosecuting attorney, she's a defense attorney. She's just petty like that.
Elita is the adventurous to the point of recklessness type. Black Arachnea is more femme fatale.
The human AU lore is still sorta vague. But the idea is that she got in some kind of accident that caused her to go bald(she wears a wig) and lose weight. Something involving radiation, maybe? Her health is bad, basically. Still toying with the idea of making her some kind of vampire-esque mutant. But idk how supernatural I want to go.
