Anyone can create a character for fan fiction. We do it all of the time. Walk down the street, or sit on a bus, and look at the people around you.
They are strangers to you, or maybe familiar faces without names, if this is a regular route for you all. Yet your mind will have already sketched an outline of their stories. The whole weight of social conditioning is behind you. Your snap judgements might be sharpened by survival instincts, or stained with inadvertent prejudices.
There are individuals to whom you warm immediately. Perhaps that old lady looks like your gran; or you see your younger self in the attitude of that teenager. Compassion born of shared experience might spark at the sight of a young mother struggling with a pushchair; or a school-child carrying a pile of study books.
Bit by bit, your imagination fills in details. That worried expression on that middle-aged man, as he turns his wedding ring around and around on his finger. Does he even know that he's doing that? Subtle body language there to betray his thoughts. Maybe he suspects that his wife is playing away from home; or he's lost his job and he doesn't know how to tell his family, nor how he's going to put bread on the table.
He's not the only one with dark thoughts. Look at how that older couple gaze pensively out of the windows, as the bus slows down outside the cenotaph. They probably knew the bright, young faces behind every name. The man's hand tightens almost imperceptibly over the knob of his walking stick. He could well have been there, fighting alongside them, watching them die; and a million memories harden the lines around his wife's eyes.
But look! They glance at one another and exchange faint smiles. Her hand moves to cover his and he whispers something. Whatever they went through, they've survived the aftermath together; and they're as deeply in love now, as they were in the Blitz. Only the years have made that quieter.
No guesses necessary for the stories of the loud gang of adolescents at the back. Every nuance of their banal lives is being screamed at volume. Not one of them can keep their seat. They're constantly fidgeting! Turning against the back-rests to speak to the friend behind; or leaping across to peer into a Smartphone.
It's Lady Gaga this; Toby off YouTube that; and 'Oh my God! Did Iggy just fart?!!' Until you're developing a headache by the time you reach your stop.
But it was a good journey and look at the cast you now have in your head. Did you picture them all? What details were there? What back stories filled in the gaps behind the lines? And more to the point, what did they look like?
None of these people actually existed five minutes ago, when you began to read. I painted them with a broad brush, so anything else that you thought was pure character creation. There wasn't even a bus.
Writing exercise: Take a walk, ride a bus or visit a crowded area. People watch; and day-dream their stories as inspiration for your writing.
Make an especial note if you automatically start mentally grouping people into 'types' or 'groups'. Ask yourself what they have in common and why you think they're so similar. These are the subtle details which will really bring your characters to life.





This should be the easy part, right? You and your readership are already familiar with this individual.



Imagine again that Death Eater gathering. Now insert someone wearing a cerise pink, polka-dot bikini, rattling on about Justin Bieber. It wouldn't quite work, would it?

I think that another key is to read, read, read. Once you can see how other people write, then you just nick all of their tricks too.
I agree with you that practice is vital. Very few people get to be Shakespeare on their first story (Shakespeare only managed that because he bore the name!)
Fan fiction is an excellent training ground; and, you're right, the skills learned here can be transferred.
Thank you for commenting!

Most of the details can be learned with practice. I see fan fiction as very very good sort of exercise. For writing fan fiction you need understanding of characters, logic, settings and a pinch of imagination.
Just like for every other sort of writing.

Thank you too for your kind words about my writing. I'm glad that it's interesting, even to someone who has no intention of writing fan fiction.

You know something that points to the success of your OC's, apart from the welcoming and love in the form of fans groups and fan art they get, is that I've noticed here and there recreation of your OCs in other peoples' Death Note fan fiction. I'm sure that I've run across a few Ann's in stories with younger versions of cannon characters, and one where they may not have actually been your OCs but some names of your OCs were definitely adopted. Ann was the most common one I ran across though...I think.
