Yup, just a Perfectly Normal Human over here! No need to question him any further. Pay no attention to how his arm seemed to stretch just now, he's perfectly normal.

I just got this weird inkling to see what Carmello would look like as a human and went along with it because why not. In-universe, I'd say he would take on this form using magic and shapeshifting when he needs to lay low among humans for one of his missions. Working with his natural color palate, he ends up becoming something of a bla-tino looking chonky boy. The form isn't perfect however. He can't convincingly alter the look of his hands, hence the gloves. And obviously if anything were to set him off sexually, his gigantic meaty cock straining against his shorts would end up drawing...undue attention...

Yes, he was told Imogene was a woman's name. No, he doesn't care.
