They're from Nyarko, a series that is inspired by Lovecraft. Its about putting all of the gods in the Cthulhu Mythos, and making them species, such as Nyarko being a member of the Nyarlothotep species. I just added in a new species, based off of Yidhra. In the mythos, Yidhra makes those who interact with her like her to a degree. She isn't an alien, just a normal human girl who gained traits similar to Yidhra's, which is why I mentioned she was a normal girl until she came into contact with one. 

Also, I think it might be for the best that you add a Universe section to the app, to avoid stuff like this.
