Gloss

Gloss was the male District 1 tribute for the 75th Hunger Games. He was a former victor, having already won a previous Hunger Games.

The 3rd Quarter Quell
Gloss won an unspecified Hunger Games, and was chosen from the pool of former victors for the 75th Hunger Games in Catching Fire. He represented District 1, along with his sister, Cashmere. He was present during training, and in the interviews, he reluctantly joined hands with the other Tributes as a sign of strength. In the arena, it is noted by Katniss Everdeen that he isn't quite swift; being shot on the calf as he plunges into the waves. Soon, after Finnick Odair, Peeta Mellark, Mags, and Katniss make their way out of the Cornucopia, Gloss and the other careers make their way back. They proved to be quite a challenge along with Cashmere, Brutus, and Enobaria; being able to kill off a few Tributes such as Seeder, Cecelia, and one of the Morphlings from District 6. Johanna Mason, Blight, Beetee, Wiress, the Female Morphling, the District 5 Female and the District 10 Male manage to escape with their lives. After the bloodbath, the Career Pack retreats to the jungle. For this year's Career Pack, District 4 wasn't included.

Death
The Career Pack later makes their way to the Cornucopia on Day 2, where Gloss slits Wiress' throat, earning him an arrow through his temple. This results in a swift death, in a simillar way Marvel dies by Katniss's hand. His sister dies shortly after, after Johanna impales her with an axe.

Family & Mentorship
Cashmere is the only person mentioned in Gloss's family as his sister, both sharing a close relationship. Gloss and Cashmere won back-to-back games, meaning that they are highly honored by District 1, as Career Districts honor their Victors

It is also presumed that Gloss along with his sister, Cashmere mentored Glimmer and Marvel. They are the two Career Tributes that entered the 74th Hunger Games.
