Bit dumb to name your character and not own the domain...
Well not really.
Sparlock wasn't a character, he was a prop. The prop was also only in 1 section of the whole dvd.
Disney doesn't own the domain for every character they create. They got the main ones.
But the villians?
Ursula.com takes you to a clothing store.
Jafar.com takes you to some photographers album or something.
Maleficent.com is unfortunately taken. . . otherwise I'd scarf it right now. But it doesn't seem to be used.
