Eulalia

To find a cure for infertility in humans, Eulalia and a research team took to work mixing chemicals and making concoctions to make a better world full of fertile people... Some several months later, funding was coming to a slow and work was in a hurried pace in order to finish the project, some persons took more risks than  others and in Eulalia's case she took a big risk.
In the midst of the night while all other project workers had gone home she took to the lab to get some extra work in and when she seemed to be faltering, she got things done... She had to test the formula... Seldom few knew but the woman had fertility problems... for years she'd been trying to be with child, her last relationship had fallen to bits because of this and fueled her desire to finish this project... The mixture HAD to work, her job was not the only thing depending on it...

We find her at the tavern these days after some... interesting results...

Since her ingestion of the fertility potion, the woman has given birth to many creatures and with each of these births her for has changed quite a bit. Once she was a plain human being with a modest figure, soft olive skin and curly black hair... Now she has become a thick lady, wide spacious hips, expansive ass, plump thighs and a hefty milky bosom of unbelievably perky E-cups.
The fertility of her being has caused her body to change with each birth, as it turns out she can birth almost any creature, insect, mammal, reptile, anything really.. and sadly, to her disdane, she has come to love all of it. She loves being with child, it does not take much to get her preggy. 

Since her first birth till not, the womans hair has become green and her head adorned with large sheep like horns (grey in color) and right on her forehead a pair of black antenni, akin to those of an insect. Her upper back sprouted massive and imposing reptile like wings while her shoulders have been covered in a mix of scales and chitin that lead intosoft brown human flesh.
Tipping her digits are long, durrable claws, able to rend steel if they have to to save her children. Fur spirals up her arm to the elbows, fading back to soft skin. It should be mentioned that behind her plump permanently black lips are sharp animal like teeth which stand out in her black mouth.
In the middle of her back, below her wings is a small hive full of hybrid insects. Extending from her tail-bone a large spider like abdomen bulges out above her large tush, the appendage is well formed for birthing, it should also be mentioned that between her legs is her human birthing organ.
While her upper legs are lightly furred, the legs themselves end in large black avian legs, huge talons clicking the ground when she walks....

Along the way the womans has birthed 4 human children, 3 complete hives of bees, 6 broods of rodents, a couple of furs, and she still seems to always be pregnant.
She's gained many abilities, telekinesis, telapathy with her children, a strong mental bond with her kin, breathing fire, ability to create life in the palm of her hand or anywhere on her body from DNA reserves... She can do many things. It does not take much to make her pregnant, even touching her can do the trick AVOID DIRECT SKIN CONTACT!
