Okay, I have decided to list my favorite antagonists and protagonists today. No special reason.
Percy Jackson (from Percy Jackson and the Olympians)
He's got a serious gift for ticking people off. And when it comes to girls, he's stuck in the middle between Rachel and Annabeth.
Auralia (from Auralia's Colors)
She's wild. Plays with animals that people are scared of. She has a talent for colors that astonishes everyone around her - and also alarms them because it's illegal.
Katniss (from The Hunger Games)
She's willing to do whatever to takes to protect her family and friends - even if it means she'll get killed in the process. She hunts illegally for what her family needs, knowing that if she ever gets caught, she'll be executed. However, when she shows up at the market with a turkey, everyone, even the people who are supposed to punish her for what she does, follows the standard protocol - bid on the drumsticks.
Mother Gothel (from Tangled)
She's rotten enough to kidnap a little girl, but treats the girl nicely. She keeps her in a tower, yes, but the tower is big and the girl has plenty to do. Mother Gothel is even willing to take a trip to the beach to get shells to make the girl paint - a three day trip.
Alexei Sarov (from Skeleton Key)
He's attempting to reinstate communism, but he's not willing to kill the spy they sent to find out what he was doing. He's even willing to adopt him, mostly because the spy reminds him of his son.
