He and Zira are the best Disney villains, I think. Scar, because he's clever and handsome - Zira, because she's crazy and scary.
As a kid, I absolutely hated Scar, because he was so evil. Well, in real life I'd still hate this kind of guy... But his evilness makes him such a great villain.
I don't like young Taka in "A Tale of Two Brothers", though. He's so irritating.
