Enobaria was a tribute native to District 2, the most loyal district to the Capitol. When Enobaria had become old enough to participate in the Hunger Games, she volunteered to perform in the 62nd Hunger Games, meaning she was 17 when she won her games. During these Games, Enobaria ripped open another Tribute's throat with her teeth. Eventually she won her Games and would be a mentor alongside her fellow victors that came before her, Brutus and Lyme, for the tributes who generally volunteered from 2. After winning the Games, she had her teeth cosmetically altered to end in sharp points, like fangs, and tipped with gold so they would be a formidable weapon as well as virtually indestructable.
Enobaria was reaped from the pool of existing victors to compete for a second time in the 75th Hunger Games. While training Enobaria fought Katniss to see her skills with a sword, though it was obvious that neither one of them was overly fond of each other and in no way wanted to form an alliance. She joined hands on stage of their interviews with the other Victors before the start of the Quell to show their strength, though reluctant to at first.
When the Quell started, Enobaria made it to shore and Katniss shot an arrow in her direction. She was able to dodge it by diving back into the water before it could pierce her. The Career Alliance formed by Enobaria, Brutus, Cashmere and Gloss stayed at the Cornucopia and undoubtedly played an important role in the massacring of 8 other Victors. Throughout the Games, the Careers stalked Katniss, Peeta, Finnick, Mags, Johanna, Blight, Wiress, Beetee, and the Female Morphling as they regulated through the Alliance of the Rebellion.
When the group, having lost both Mags and the Female Morphling, made their way to the Cornucopia, the Careers attacked, Cashmere and Gloss died shortly after killing Wiress, Enobaria also throws a knife at Peeta but Finnick steps in the way and it lodges into Finnick's leg before she and Brutus leave, they stalk the group again until Beetee sets his plan into action.
Together Enobaria and Brutus chased Johanna and Katniss across the island, until Johanna dug out Katniss' tracker and made her look dead so the two would pass by her. At an unknown point they split up, Brutus finding his way to Chaff and Peeta, in the battle managing to kill Chaff but then being killed himself by Peeta seconds later, leaving Enobaria as the only remaining Career Tribute.
Enobaria fought her way to Beetee and managed to stab him so he could not complete his mission of destroying the Arena. She was chased off by Finnick while Katniss figured out Beetee's intentions. By the time Enobaria and Finnick had made it back to Katniss and Beetee, Katniss had just destroyed the Arena and called a stop to the Games, leaving six Tributes still alive.
Plutarch was able to rescue Beetee, Finnick and Katniss. However, Enobaria, Peeta and Johanna were apprehended by the Capitol. While Johanna was tortured with electroshock tactics and Peeta was being tortured with hijacking, Boggs speculated that the Capitol set her free as they were unable to retrieve her in a rescue mission that brought the others to District 13. Though when District 2 was conquered and District 13 had shown to them that they are needed in the rebellion, Enobaria joined the rebels.
After the war was finished and the execution of President Snow was all that was left on the agenda, the only remaining victors in all of Panem were called to discuss the reboot of the 76th Hunger Games that only Capitol children would be part of. Enobaria, Beetee, Annie, Johanna, Katniss, Peeta and Haymitch were the only surviving Victors now (With the death of Finnick in the capitol and the Victor Purge of the Capitol killing Lyme). Enobaria's life was spared by the Rebels because of the Mockingjay deal that Katniss had Coin promise to. Whether the 76th Games were to occur would be decided by a vote of the remaining Victors. Enobaria, Johanna, Katniss and Haymitch all said yes to another Hunger Games. It is likely Enobaria went back to living her life in District 2 after this as she was not heard from again and she was not killed.
- Near the end of The 75th Hunger Games, Enobaria was chased away from Beetee by Finnick, but the two returned together and began searching (for either Beetee's or Katniss's location). The fact that Enobaria and Finnick were not fighting to the death makes it probable that Finnick told her about The Rebellion while they fought.
- Enobaria and Annie Cresta are the only career tributes alive after Mockingjay. Enobaria is the only career tribute who participated in multiple games to survive the rebellion.
