A month ago I made an alternate non-Digimon design for Girl Gaomon. I worked on it a bit more and came up with this. A mad scientist of sorts, and a mutant (took her a year just for good control over those extra limbs).

Heyuu Girl is, as it was for Girl Gaomon, a self given name. In this case, most people tend to not remember her actual name so she went by "Heyuu Girl".
