an alien princess from a royal family bloodline of princesses of the water element

This is Nicoshida from the Wonderfully Weird World of Gumball. (Art by foxstarlight005) And yes in this AU Nicole Watterson (one of Nicoshida's two halves of the Synthesis technique that made her) is single and also has no kids, so she is dateable for those who want to fall in love with her or her fusion counterpart "Nicoshida." For those who dont know, the story is set in the fictional city of Elmore, where various beings, including animals, mythological creatures, and anthropomorphic objects, coexist. (Create your character and story, and most of all, have fun)
