Yeah, this was how my art was in 2000 when I still lived with my parents, Janet is on the right and Dark, who USED to be Janet transgendered on the left.

Petty me I used Star Wars and the popular beam sword from Mega Man at the time when Zero was introduced to have Dark actually bring something into my art back then :P
(Yeah, I used emulators and roms for Mega Man)

Doodled one day on whatever in 2000, this was Janet's first rendition I have ever drawn and the first time I created her :)

Dark is only a mirror image of her in male form, which I found several years later after improving, to being the Janet we all know.
Basically, Dark Hedgehog is now and has been Janet all along :)
My story to Janet revolves around her being Dark but changing into a full female and ripping anything male out of her including personality and appearance.

That's Janet there, amazing how cruddy my work was back then, eh? XD
