Dear “Tag Your It” Author,
Let me begin by thanking you for offering one of my fandoms. I'm sure I'm going to love whatever you write, but since you're probably looking for some ideas and guidance, I'll try to provide you with some suggestions. Note that I've requested many of these things before, and have received some great stories, but I'm of the opinion there can always be more. I love seeing alternate takes on the same basic idea.
First, some general wants/do not wants.
Wants: (Things I especially like, if they happen to fit in with the story you want to tell.)
Snarky characters, physical or mental h/c, humor, PWP, gen, character studies, adventure, women or other characters who are usually in need of rescue turning the tables and being the hero, fix-it fic, A/Us in which events transpired in slightly different fashion. Note that I'm fine with drunken dub-con/aliens made them do it/sex pollen/the like.
Do not wants: (Things that I'm either not interested in for this exchange or that simply don't work for me with the fandoms and characters I've requested. Do note that there are fandom specific exceptions that will be listed under those fandoms.) Character death, non-con, a/b/o, genderswap, male or female pregnancy, kid fic, curtain fic, coffee shop/band/etc type A/Us, most kinks other than some mild bondage.
Now, on to the specific fandoms:
Group: Danica Patrick & Tony Stewart & Kurt Busch & Kevin Harvick
This was the team that most fans (myself included) expected to see implode in short order. Oddly, they've gelled well together, but one does wonder what sort of craziness goes on behind closed doors. Please, avoid any serious racing accidents, although fist fights are more than welcome. Feel free to add any other drivers you'd like.
Magical pants (British pants preferred) – When I saw the tag, my first thought was a lucky set of underwear that's being shared (perhaps not willingly) among the team. Of course, they're a bit big on Danica, and a little small for Tony...
Alien invasion or Zombie apocalypse – Team Stewart tasked with saving the world? Or at least Daytona?
Bar Room Brawl – Don't tell me that you can't picture this...
Road trips or Vacations Gone Awry – Do you remember the series of Coke racing family road trip ads? Send the team on a trip together.
IN SPACE – I'm mot usually big on A/Us, but Team Stewart crewing a starship? Yeah!
Crack fic, Humor, Comedy, Team Dynamics – mix with any of the above, or if you have an idea of your own.
Big Bang Theory
In this fandom, I have differing tags depending on which characters you select. My favorite character is Sheldon, who I ship with either Penny or Amy, if you want to go that route. But, that said, I'd love to see something focusing on the group as a whole, too.
Group: Sheldon Cooper & Leonard Hofstader & Howard Wolowitz & Rajesh Koothrappali & Penny
Time travel – The boys invent a time machine. Things go very wrong.
Character turned into Cyborg or Android – Sheldon would be the first to volunteer, wouldn't he?
IN SPACE – The group as crew of a spaceship, boldly going... well, knowing this group, going around in circles?
Crossover w/Stargate Atlantis – Perhaps Penny has the ancient gene so she gets to go, too? The five would make an interesting (and terrified) gate team. And Sheldon vs. McKay?
Secretly an alien – One would expect it to be Sheldon, but maybe it isn't?
Power outage – Sheldon's emergency drills come in handy.
Group: Sheldon Cooper/Amy Farrah Fowler
Impact play, Breathplay, Sex toys under clothing – Remember the episode where Sheldon spanked Amy and she enjoyed it? I could picture Sheldon experimenting and lecturing Amy on just why her body responds that way.
Group: Michael Coldsmith Briggs III & Caitlin O'Shannessy
Group: Michael Coldsmith Briggs III/Caitlin O'Shannessy
Personally, I ship Michael and Caitlin, but I know that's a rare ship, and I'm perfectly happy to see the two together in a platonic relationship. Michael is my favorite character, so you really can't go wrong with anything focused on him. However, I do request that if you go the platonic route, that you don't ship Hawke and Caitlin together.
Post-canon or A/U Canon divergence – If you can find a way to explain why Michael and Caitlin were both missing from the fourth season, or if you want to ignore the fourth season entirely, go for it.
Rescue Missions – for once, it's Michael and Caitlin saving Hawke and Santini?
Undercover as a couple, Undercover Missions or Spies & Secret Agents – Caitlin gets roped into going on a mission with Michael?
Scars, PTSD, hurt/comfort, emotional hurt/comfort or dreams and nightmares – Michael has been tortured, drugged and blown up, surely he has some baggage from it all? Maybe Caitlin is smart enough to see it?
Snowed in, Sharing a bed, Huddling for Warmth, Secret relationship, Handcuffed together, Porn what plot or Porn with Plot – Throw them in bed together, I don't care how. :)
I love the snark, and the relationships between the characters. I'm flexible regarding John and Rodney, either ship or bromance is fine. That said, I also love Todd, the honorable enemy.
Group: John Sheppard & Rodney McKay & Todd
Group: John Sheppard & Todd
Friendship, Frenemies, comrades in arms, loyalty – Anything exploring the complicated relationship between Todd and Atlantis.
Transformations, Villains to heroes, post-canon, team dynamics – What if Keller and/or Beckett find an answer to the Wraith's need to drain humans of life force, and Todd becomes a part of the team?
Love this show. Another case of different tags for different characters.
Group: Richard Castle & Victoria Gates
Frenemies – She likes him a lot better than she ever lets on.
Group: Richard Castle & Kate Beckett & Javier Esposito & Kevin Ryan
Group: Richard Castle/Kate Beckett
Group: Richard Castle & Kate Beckett
IN SPACE – Star ship captain Castle?
Crossover w/Stargate Atlantis – Castle with the gene? A Wraith loose in NY murdering people? Castle and friends enlisted as a gate team?
Alien invasion, Vampires, Monsters – real ones this time.
Character turned into a Vampire – What if Castle got bit? Immortality cool. Blood drinking and sunlight allergy not so cool?
Hopefully, dear writer, you've found something that interests you. Just have fun writing and don't stress, I'm sure that whatever you come up with will be great!
