For some, I haven't even written three...
In Sailor Moon, I've drawn a lot of pairings,
but writing-wise, it's almost wholly gen.
I did enjoy this Artemis & Luna:
an understated, geeky sort of romance.
My Hellsing OTP will stand forever:
Integra/Alucard, beloved Master
and her beloved pet. A runner-up
is Yumiko (and company) and Heinkel:
an OT3 at minimum, with Issues
enough to write a book or two apiece.
Integra/Seras caught me by surprise;
I noticed that I'd started writing Seras
as crushing on Integra (well, who wouldn't?),
and then she grew to be the kind of person
Integra could admire back...I shipped it
before I really noticed what had hit me.
The rest in Shine have one top pairing each.
There's Nenene and Sensei, D and Leon,
Utena/Anthy, Crowley and his angel,
and Jeeves and Wooster. (Not a ship at all
in Robin.) None get written much regardless.
In Oz, I'm all about the Dorothy/Ozma.
There's other ships I like, but haven't tackled;
I hope one day a plot will come along
that calls for writing Scarecrow/Scraps/Tin Woodman.
For Doctor Who, again, I've only written
the one, and it's Maria/Sarah Jane.
The Daily 'ships, I'm sure you all can guess!
It's hard to go astray with "Stephen"/Jon.
You name the prompt, the setup, or the item,
and I can write them into it, no problem.
I love me some Olivia and Kristen,
though mostly 'cause Olivia is awesome
and Kristen is my preference for her partner.
It's hard to figure out what comes in third
(I figure AU!"Stephen"/Jon can't count).
Discounting other Jon-and-"Stephen" 'ships,
I'm thinking Tad and Bobby win the day.
For Madoka, there's HomuMado, easy.
They'll move the world to make each other happy.
It's hard to beat perfection, but I'll try
when writing Madoka-with-Everyone.
She loved them all enough to lay the smackdown
on basic laws of physics; she can love them
enough to have a poly yuri harem :D
I'll be cliche and let the final slot
be filled by SayaKyo. I didn't see it
as strongly in the series, but the more
I write the two of them, the more I feel it.
