President Alma Coin

Alma Coin is an antagonist in Mockingjay, the third Hunger Games book. Even though she is not a partner of the dictator, she is a major villain for tricking Beeta and Gale into killing servants and Capitol people. She killed Katniss' sister, Prim using a bomb. She has a harsh hatred on the Dictator or almost anyone who is associated with him in any way. She is executed by Katniss near the end of the book, rather than President Snow being executed
