Scar. Why? Scar was a tyrannical King who murdered his own brother and supposedly his own nephew, didn't care for his own Pride and the well-being of his kingdom and he is very manipulative and will get what he wants.
He's also cold, cruel and selfish but did he ever show signs of a 'heart'? Well. If you believe that the SP outsider cubs are his kin, then what kind of father and lover would he be? He may also be the reason for Zira's nasty and hateful nature. Love and Rejection can do that to you after all...
But nonetheless I still luf him. <3
When I think of what that BRUTE did.. I get a little TENSE!
