In Suzanne Collins's *The Hunger Games*, Thresh is a formidable and enigmatic tribute from District 11. He forms an unlikely alliance with Katniss Everdeen, but he ultimately chooses to protect Rue, a young tribute from District 11, over Katniss.
While he's not killed in the Games, his fate is left ambiguous. After the Games, it's implied that he was probably killed by the Gamemakers for breaking the rules by protecting Rue.
It's important to remember that the Hunger Games are a brutal and unforgiving event, and many tributes, including those who are not directly killed by other tributes, suffer a violent end.
