Mine matches my user name, obviously. Dr. Franken Stein from Soul Eater. I'm a cosplayer and that's my best costume. I even knitted the stitch sweater from a pattern I wrote myself.
The darker end of it is that I'm addicted to SteinXSpirit yaoi and my irl boyfriend cosplays as Spirit the Deathscythe. If we're both on the same site he'll make an avatar with Spirit's pic to match mine. [Usually cut from a piece of artwork that showed both of them.] It's an ongoing game that caused me to write an extremely explicit yaoi that topped 15 pages. [Most of it a true confessional of things I've done to him with the names changed.]
[Since the Op mentioned telling a story.]
I'm actually an author with eight finished novellas, so the yaoi is on my personal site as a writing sample if anyone wants to read it. (18 and over only please)
