Alma Coin

President Alma Coin was the President of District 13 and the leader of the rebellion against the Capitol by the people of the districts of Panem. She is the secondary antagonist of Mockingjay, after Snow and the Capitol. She was first introduced when Katniss Everdeen met her in District 13.

Biography
Coin was presumably raised in, and served as the leader of District 13 and the rebellion. Due to Katniss Everdeen's unique position as a symbol of rebellion to the districts, Coin had Katniss, along with Finnick Odair and Beetee rescued from the arena following the 75th Hunger Games, after Katniss destroyed the sheild surrounding the arena. This action effectively prompted The Capitol to bomb District 12. However, she was not able to rescue Peeta Mellark, or Johanna Mason. With Katniss safe in District 13, Coin was forced to cooperate as she recovered from her physical and mental traumas, although she was rather impatient. Like the other rebels, Coin needed Katniss to don the label of Mockingjay, and help fuel the Districts into rebellion.

Death
During the execution of President Snow, Katniss remembered the conversation she had with Snow and realized President Coin was behind Prim's death. So instead of shooting Snow, she turned her single arrow from Snow to President Coin and shot Coin instead (partly to avenge Prim's death). President Coin fell off the balcony as the people looked on in fear and horror. It is possible that she didn't die from the arrow but from the fall itself. This resulted in Katniss being taken away and declared mentally unstable.

Personality
Though she and Katniss were on the same side, Katniss strongly disliked President Coin because of her ruthlessness and hunger for power and absolute control. Despite her affiliation with the rebellion, she seemed even more ruthless than President Snow, since Katniss believed his explanations, but not Coin's. Coin was willing to let Katniss die once she had fulfilled her duties as the Mockingjay, since she saw the girl as a possible threat to her power. Katniss believed her death would incite the rebel force to further Coin's victory. Coin's lust for power was such that she killed Capitol children and her own Medical Corps—with Primrose Everdeen amongst their ranks — to undermine Snow.

She was also very manipulative. According to President Snow, Coin's plan all along was to let the Capitol and the other districts destroy one another, and then step in to take power with District 13 intact.

Physical appearance
President Coin is described as being about 50 years old. She has grey hair that falls in an unbroken sheet to her shoulders, her eyes were a pale grey, described by Katniss as being like "slush that you wish would melt away". Coin was described as plain, with eyes that could burn straight through you.
