Ten Things I Hate About Your Antagonist
As evil/psycho as the antagonist is, everyone in the story loves and/or admires her, except for the protagonist, who from the beginning and with no evidence whatsoever somehow senses that she's up to no good.
It must be the same psychic power that also allows the protag to fall totally in love with a complete stranger in less than 24 hours.
Beauty, wealth, power and social position are never enough for the antagonist, who will without hesitation throw them all away for a single, slim chance at revenge.
Didn't someone send her the memo about how beauty, wealth, power and social position are, in fact, revenge?
Despite the vastness and complexity of his personal arsenal, the antagonist never carries a backup weapon or extra ammunition.
That would ruin the moment when he throws his empty weapon at the protagonist's head, I suppose.
Five words sum up the antagonist's ambitions: "I will destroy the world."
Oh yeah? Here's seven more: Afterward, where are you going to live?
The antagonist chooses for his sidekick someone whose IQ is in the low two digits.
Sure, when I want backup, I definitely consider "criminally stupid" as a primary job qualification.
He's never loved a single person in his entire miserable life, nor has ever shown any interest in anyone but himself, yet upon seeing for the first time the protagonist's love interest, the antagonist also falls head over heels for her, too.
Blinded by the awesome glitter of her hooha, I guess.
In spite of a long history of bad behavior, no one the antagonist has ever messed with comes after him with their own plans for revenge.
Naturally they're all sitting at home and silently seething while they stick pins in an antagonist doll.
In the middle of the final crisis in the story, when she has the upper hand over everyone, the antagonist proudly delivers a full confession of all the wrong she's done.
Hmmmm. Maybe she's Catholic.
The antagonist honestly believes that if she eliminates her romantic rival that the protagonist will subsequently, instantly fall for her.
Naturally the moment we lose the love of our life we want to jump right into another relationship.
When he's finally in a position to actually bump off the protagonist, whom he's wanted dead since page one, the antagonist immediately thinks of a reason not to kill him.
This usually involves some sort of extended period of suffering that is also rife with oppotunities for escape, payback, alerting the authorities, etc.
