Isa looks like that partially because they wanted to make fun of Benz for being super uppity about how not gay he is. They normally look very feminine and cute. XD Extra fascinating for the event they went to
Yeah I looked through Mindless-Corporation's profile and for pictures of Isa, and I kinda figured at least ONE picture would have depicted a form like the one you drew, but I didn't find it. Isa's still a really neat character nonetheless.
This image was a reveal of sorts of their new manly form so at the time it was the only one LOL. I dont think corp uploads too often though, so i dont think there are more of this version in their gallery still.
