I used to do yearly round-ups where I'd talk about the best (read: my favourite) literary characters I encountered in a given year, be they old favourites or new flames. It was fun, but it took forever and I got bogged down on, like,
justifying my opinion and stuff, so I let it slide.
I did encounter a great many wonderful characters in 2014, though, so I figure it's about time for a revival.
These aren't necessarily my favourite literary characters of all time, and they don't necessarily appear in my favourite books of 2014. They are, however, the characters who captured my imagination last year; the characters who made me want things on their behalf; the characters who refused to be ignored.
Y'all should make an effort to meet them your own selves.
In more or less the order I encountered them, they are:

Jewel Markess ATerafin from Michelle West's Averalaan universe - West has created many a fascinating character (not all of whom I've met yet; I'm reading this series so damned slow), but Jewel is the one I really clicked with. She's got her chosen family, and she's going to protect the hell out of them no matter what. I love her for it.
Medrault from THE WINTER PRINCE by Elizabeth Wein - the first in a long, long line of characters dealing with trauma. (2014 was my Year of Fictional Trauma.) I spent an entire book with him, but it wasn't until the very last page that I began to figure him out.
FitzChivalry Farseer from Robin Hobb's Realm of the Elderlings series - as I approached my massive Robin Hobb Reread/Catch-Up in preparation for FOOL'S ASSASSIN, I found myself most excited about considering Fitz again. Really delving into him, you know? Psychologically and stuff? It was every bit as good as I expected it to be, so I had no choice but to add him to my (Highly Exclusive) List of Favourite Literary Characters.
