Wiress King, 16 (Currently 43)
District 3

Wiress had won her Games because she had to leave her true love, Beetee Latter (see 44th Hunger Games) in District 3. Wiress won her Games when she killed the boy from District 4, but her speech was impaired during the battle when he hit her in the head with a club. Beetee was the only one that knew what Wiress was trying to say and they later got married and had two children. 

50th Hunger Games: Haymitch Abernathy (D12)

Haymitch Abernathy, 16 (Currently 42)
District 12

Haymitch was an amazing contender in the Games from the start, and only became better as the Games wore on. When he got cornered by the careers, he quickly killed two of them. But the last one was faster and bigger and disarmed him. Haymitch was sure he was about to die when his fellow tribute from 12 killed the brute for him. They stayed allies until Maysilee died. Haymitch later won by using the forcefield to his advantage. He also helped lead Katniss and Peeta (see 51st) to Victory and create the first consecutive Victories for District 12. He currently drowns himself in liquor, and helps Katniss and Peeta raise his niece and nephew.

51st Hunger Games: Katniss Everdeen (D12) and Peeta Mellark (D12)

 Katniss Everdeen, 16 (Currently 41)

Peeta Mellark, 16 (Currently 41)

Katniss and Peeta won their Games symbolicly. Katniss didn't think it would be fair to let Peeta die in the arena, so she threatened the Capitol with the suicide of both of them - meaning they would get no Victor - and they let them both win. They almost started an uprising, but their undeniable love proved true on their Tour and the act was not taken as a form of rebellion but as a form of undying love for one another. They later had two children (Arielle Mellark; died in the 75th, and Hunter Mellark; won the 76th) and eventually did play very important roles in the Rebellion.
