In a universe without humans, mobians are the first species to inhabit the planet and have humanoid bodies. No chaos emeralds, chao's, or humans exist.


Around the 18th century, a meteor hit Earth and contained a cum like slime and with it contained an Alien parasite.


The alien parasite affected a female mobian after discovering the crash site, when she was infected with the parasite, she developed male genitalia due to the parasite's affection, She had consensual sex with her partner, and they discovered that if the afflicted host with the parasite has consensual sex with someone, the parasite will transfer its essence into the person. Following this ordeal, the pair with the parasite chose to spread this parasite on to people they knew about, which continued to spread faster and faster to the point that all of mobius has been infected by the parasite.


The parasite will develop abilities if it has been present in the host for a while.
-Replacing a person's genitalia permanently, such as turning a man's genitalia to a woman's or a woman's genitalia to a man's.
-Providing sexually transmitted illnesses while engaging in sexual activity.
-Expand the anals, mouths, and vaginas to an endless number of spaces.
-Eating and drinking foods and beverages flavored with cum to stay alive and well.
-Nigh absolute immortality.
-Improving a person's strength and intelligence.
-Using cum and breast milk for electricity, drinks, power reactors, and other things, as well as masturbating plants to make cum-flavored food.
-Having children in a week instead of mounts, If a male breeder engages in sexual activity with a female having male genitalia, he will get pregnant and lay cum-like eggs. When these eggs hatch, they will give birth to young adult mobians rather than infants, as opposed to being born through the womb in the stomach.
