Biography
During the 75th Hunger Games, President Coin starts the second rebellion against the Capitol to take control over Panem. As she needs Katniss Everdeen for her unique position as a symbol of rebellion to the districts, she rescues her, Finnick Odair and Beetee from the arena and hide them in District 13. This caused the Capitol to bomb District 12, Katniss's home, but Coin showed little emotion to this.

However, Coin soon discovers it is hard to cooperate with Katniss, who dislikes her for her selfishness and ruthlessness. Coin often regrets openly she couldn't have saved the more charismatic Peeta from the arena instead of Katniss.

Before the attack on the Capitol, Coin realizes Katniss could menace her position of President, as people still love Katniss more than her. To destroy her rival's psyche completely, she decides to murder someone Katniss really loves. In the Capitol, Coin uses a Capitol hovercraft to launch bombs (placed in supply packages) on some children. When they blow up, Rebel medics, alongside with Katniss' sister Prim, run there to help injured kids. However, once they reach them, the other bombs blow up, killing all children, medics and Prim. After that, the Capitol gives up to the rebels.

Katniss, who saw her sister die, is now heavily dazed. Coin becomes the new President of Panem. She decides to organize the last Hunger Games in which children of the Capitol would fight to death. However, Katniss foils this plan. Thanks to Snow, Katniss realizes the President's goal: she planned the rebellion in the districts by having them fight it out, leaving District 13 untouched; once the districts were hers, the Capitol could easily be nabbed. Katniss then shoots Coin with an arrow, sending her over a balcony to her death. Snow laughs at this as a massive mob of shocked citizens surges towards him and Katniss, killing him.
