I would make Mayor Prentiss from the Chaos Walking trilogy (The Knife of Never Letting Go/The Ask and the Answer/ Monsters of Men) by Patrick Ness, and President Snow from the Hunger Games trilogy fight. To the death preferably. I picked those two because I hate them both and I would like to see one of them die...lol. They are quite similar in a lot of ways too; both manipulative and great multi-layered villains. I think a fight between them would be very interesting as both would employ very sneaky tactics! I'm not sure who would win but I would have to put my money on President Snow because, in the end, he is simply more ruthless than the Mayor and doesn't have as strong a relationship with the main character.
Thanks for reading and for following! I love me some followers.
