Here is Zipp Storm/Zephyrina Storm as Zephyrus Storm

He is the easiest to draw since why change perfection? XD
I mean Zipp is very tomish in her own way, if she was a male, I don't think she would suddenly be into girly shit as a male. I think Male Zipp would not mind the girly stuff but still act the same. So the hair is almost the same so make what you do, I think Zipp is perfect without the super changes unlike Pipp or the others.

Keep In mind that Genderbend characters is supposed to change the gender, Not the whole Personality nor the whole last name part,
yes, they can act different from their main Counterpart, but it should be at least similar to it.
BUT hey this is my Opinion to what Genderbend is to me and how I make it.
