This should be the easy part, right? You and your readership are already familiar with this individual.
Another author has already envisaged how they look, act, speak, think and react in certain situations. You know their stories and what they like to eat and drink. You have their idiosyncrasies and traits already laid bare. Their favorite music, hobbies and fashions are there for the plundering. You can deduce the sort of people they love, hate and who becomes their friends.
You know all of that, but so do your readers. Fandoms form around personalities (fictitious or otherwise) with whom enough people identify. They are all seeing something here, which chimes with something inside themselves.
To spell this out: whatever you write about their favorite canon character could easily be framed as a commentary upon themselves. Tempers could get frayed accordingly.
Moreover, everyone's an expert. Each one of your readers will secretly believe that he or she is this canon's number one fan. If you interpret the character in a vastly different way, then you should be prepared to defend it with endless reference to the original source.
If you can't, then the next accusation will be one of having written out of character (OOC). If you're doing that, then you're not writing fan fiction. It's an original story with stolen names. That's false advertising again!
There are only three ways to avoid that:
The first is to simply rewrite the canon without changing much at all. Not only is that boring, but you've immediately placed yourself in a side by side comparison with the original. That's the one with the fandom and the sales. Good luck there. Shakespeare pulled it off with Romeo and Juliet, so there is hope.
The second is to openly state, in the author's notes or introduction, that you're being experimental. It will be OOC, but you wanted to see what would happen if some details were different. If your pride can stand it, then this will head off any criticism and render fans more open to your interpretation.
The third will demonstrate precisely why rewriting canon characters is not the easy part. It involves sitting for hours, days or weeks scrutinizing every bit of every scene and taking notes. You need to justify every fact, every inclusion, every whim of characterization.
Not only will this result in a person on your page which should be recognizable, but it will be your defense against OOC characterization. Actually become the expert that everyone thinks that they are; and be ready with chapter and verse to refute all comers in the comments.
Recreating canon characters is like walking in somebody else's footsteps across a snowy field. Everyone can see precisely where you should step, and will know instantly if you're out by just an inch. Why on Earth would anyone assume that's easier than simply forging your own path to the other side?

I'm glad that you liked 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!
Some very good ideas here. I come from environment where a lot of people still believe writing is matter of talent, inspiration, act of muses etc., but younger generation already showed most of tricks of the trade can be reproduced and difference between great writing and good enough writing is only in details.
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.
Ann's made it into fanon?! :o My jaw is literally dropped here. I had no idea! Thanks for letting me know!
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.
Writing is an art you really have such a talent for. I'm enjoying your writing an OC series, even thought I don't write. Its like little insights into how creative writers do their thing. I can see how one small detail can end up crafting a scene for you. Nifty!
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.
