Connor Lowell
Connor was the unlucky male Tribute of the 73rd Hunger Games for District 10. Until then, Connor was just a nameless nobody, even now, unless you mention him by name. His nickname that is.
He is nicknamed the "Wolf" by those Capitol Residents who still remember him. The being so named because he "tore the other tributes apart like wolves". If only it wasn't true.
Most of Connors time spent in the arena, he was suriviving, he lived off the land and allowed the others to kill each other. After all, who would remember the farm boy from District 10?
It wasn't until the last day of the games he was remembered by the other tributes. Connor and four other career tributes remained. They had drawn Connor out of hiding, forcing his death so they could backstab each other.
Even if there were four of them, they over estimated themselves. They taunted Connor, waving their weapons around proudly. Connor only had one weapon, a knife. But he never used it.
They had attacked him one by one, weapons first, but Connor had disposed of all of them, with only his barehands. He had gotten badly torn up in the process too, a couple of organs needed replacing.
When he was healed and gotten back to Capital to be named the Victor of the 73rd Hunger Games, he was already nicknamed the Wolf.
Since his time in the arena, he has grown quiet, earning the nickname the "Lone Wolf" by the other Victors and those in his District.
