Most people like villains more than the actual hero.
Why? Probably because they usually have much more interesting stories. Now I know not everyone will agree with me on this. But who doesn’t have a love/hate relationship with villains like Maleficent or Evil Queen?
So it’s no surprise that changing their gender doesn’t really effect them that much.
#1 Captain Hook – Peter Pan.

#2 Fidget the bat – Basil the Great Mouse Detective.

#3 Gaston – Beauty and the Beast.

#4 Hades – Hercules.

#5 Jafar – Aladdin.

#6 Lago – Aladdin.

#7 Oogie Boogie – The Nightmare Before Christmas.

#8 Scar – The Lion King.

#9 Wiggins – Pocahontas

#10 Yzma – The Emperor’s New Groove.

Yes, she did retain her gender but she still looks cool as heck.
