A Guide to Making a Hunger Games Character

Twirl For Me

No, this is not the start of a bad porno. I promise.

Sweetmeat Applepie Honey Melon Dewdrop was a beautiful girl. Her hair fell down to her plump, perfectly-shaped ass in delicate, luscious waves of honey golden lilac blonde. Her bright blue silver orbs flashed with intelligence and splendour. Her petite, voluptuous melons were perfect, given her name, and she had curves in all the right places. She had naturally manicured nails, abdnsagDLFngzhnsdjh5456topytryj/l;/nb.nh

Sorry, that was the sound of me smashing my head on the keyboard so hard my brain liquidised and splashed from my ears in a beautiful greyish-pink waterfall.
Please, my darlings, don't EVER write like that. Nobody wants to hear about how petite and voluptuous Sweetmeat's knockers are. Nobody can have both petite and voluptuous anything, so don't even think about writing that sentence.
And the writing is completely ridiculous; it wouldn't even get a passing grade in a descriptive writing exam.

District 1
If you're from District One, you're most likely going to be beautiful. Think about Hitler's Aryan race. Blonde hair, blue eyes, tall. So basically everything that isn't me. You might have light brown hair and green eyes, and you'll probably be tanned and gorgeous. But not Finnick-gorgeous. Nobody is as beautiful as Finnick.
You're not going to be malnourished. You're not going to have "your ribs sticking out and elbows so sharp they're like the blade of a knife", to quote Melia. You might be slim, but chances are you'll be laden down with muscle. That means that you won't be able to run as fast as, say, someone from District Seven.
And please, for all that is good and holy, DO NOT describe your character as I have Sweetmeat Applepie Honey Melon Dewdrop. Chances are, nobody wants to hear about how perfect your knockers are (if you're a girl). And they especially won't want to hear about how perfect your knockers are if you're a boy.

District 2
The same mostly applies here. No malnourished characters, no disgustingly thin tributes (unless they have an eating disorder, but even then you've got to have a really good reason for that), and your character will most probably be very muscly. Because if you're from Two, you'll be working in the mines, in the factories, or training all day.

District 3
Those from Three are describe – for the most part – as being skinny, pale and dark-haired. The citizens of Three despise the Capitol and want absolutely nothing to do with the Games, so they won't be training up their kids to fight in them. And being quite poor, it's entirely likely that you can get away with a skinny little idiot.
Because you'll most likely get a job in a factory in District Three, your character is going to be pale (Beetee and Wiress are described as both having ashen skin). So basically, don't make a drop-dead gorgeous, blonde, voluptuous, bronze-skinned female if you want to be realistic.

District 4
Most citizens from Four spend their time out in the sun fishing all day, they are going to have bronze skin. They will be muscly. They will have golden or light brown hair. They'll most probably have sea-green, grey or blue eyes. They will be absolutely bloody gorgeous. That's not an invitation to write like you've just vomited a rainbow kitten fairy all over the page.

District 5
Little is known about most people from District Five. But, since they are the power suppliers one can assume that most citizens spend their time in factories. And from Foxface, we know that it's likely that a lot of citizens would be red-haired. Don't stray too far from this. Green or brown eyes, red or brown hair. Pale skin. Possibly freckles if they spend more time outdoors, but this is unlikely. 

District 6
Again, little is known about the people of District Six. We have Titus, who was brutal and became cannibalistic during his Games, and we have the two morphlings who were, quite frankly, adorable.
Since District Six's main industry is transportation, The Hunger Games Wiki says that the jobs offered there are porters (they move cars in and out of car dealerships and park them) routers (presumably they have something to do with roads) mechanics (they fix vehicles) conductors (train conductor, they are responsible for the activities of passengers and crew on a train, and help passengers as needed) and baggage handlers, which is fairly self-explanatory.
So it's likely that your tribute will be strong and probably quite dirty, with tanned skin. Don't make them too strong though - they're not a Career.
