Maybe it's not the best idea, partly because I don't remember all of my fandoms, but while I have time...
Fandoms in bold mean major obsessions
Italics is for passing attractions and/or fandoms where I just lurked for a while
Underlined means that I'm not really in the fandom but like the idea.
Pairings are treated similarly.
Also "*" means a fic written in the fandom, and "#" means a fic posted somewhere online.
Crossover "*"s will appear in every fandom of the crossover.
So, here goes.
Air Gear #############****
SupiSano (Spitfire x Sano), Sano x Kazu,
SupiSano's been my obsession for quite a long time. And considering it's not a popular pairing, and canon!Spitfire is dead... Well...
Akuma no Riddle
Tokaku x Haru
SureIna/InaSure, Mazuurek x Harklight
Kon x Toki, Bonten x Ginshu
Ginshu is really male. He really, really is, no matter what canon says about his 'transformation'. So, there. *threatening look*
Karma x Nagisa
Antique Bakery ##
Ono x Chikage
I don't know, I just love these two together. Screwed up Ono and blissfully dumb Chikage make sense to me.
Ao no Exorcist
Rin x Yukio
Me and my obsession with twincest...
Aoharu x Kikanjuu
Matsuoka x Yukimura, Hotaru x Kanae
Aoi Hitsuji no Yume #
Ratri x Kai
Major obsession here. Really major. But nearly dead fandom and lack of scanlations to go with it. Damn, life is unfair T_T
Daryun x Arslan, Daryun x Narsus
someone x Ryuu crossover would be nice...
Too bad there's no one in canon to pair with Ryuu. At one point I might despare enough to write an OMC/Ryuu.
UPD 2015 That ship just didn't sail for me. It was nice while it lasted though...
Not that it's really my fandom... I liked Ryuusuke x Koyuki at one point, and I've written a Taira/Koyuki drabble as a gift/meme game prize, and that's about it.
Toujou x Ouga, Himekawa x Kanzaki
Oh, I've been there for a looong time... But finally I got fed up with monotonous, mindless fighting, so I don't even read the manga anymore. But I still have Urahara as my default icon ^_^
UPD 2015 Not even that anymore.
Carlo x Magira
One volume of manga and so much obsession... Somehow I just love the characters, and I'm even planning to write them for the Valentine's Day Drabble Collection of DOOM v.2011
UPD 2015 Didn't happen
Taichi x Arata, Shinobu x Chihaya
Concrete Revolutio: Choujin Gensou
Nephrite x Jadeite
Strictly speaking, DK is part of Sailormoon fandom, its season 1. But in reality it's a completely different fandom, at least in Russian-speaking sector of internet.
Yes, I was part of this mass madness, too. Doesn't make me proud.
Devil May Cry ##
Vergil x Dante, Trish x Lady
Who can resist delicious silver-haired polar-opposites-temper twincest? Not me, that's for sure ^___^
Yamato x Hibiki
Donten ni Warau
Tenka x Shirasu, Shirasu x Kotarou (<- whitehaired twins. 'Nuff said)
I'm not even writing any pairings here, because my love for Evangelion has nothing to do with romance in any form or shape. It's the concept, the psychological and philosophical undercurrent, and everything else not related to pairings. And of course it's Kaworu. I've taken this nickname for a reason.
Dee x Ryo
Manga was nice. Graphics style sucked.
Full Metal Panic ***
Fullmetal Alchemist #####
Roy x Ed, Russell x Ed, Greed x Ling
My love for rare pairings be damned. I'm not the only author who wrote Russell x Ed, but close enough.
UPD 2015 Roy x Ed sails again, if only as 'comfort food'...
Kaoru x Keita, Niwa x Keita, all of the others
I don't know, I just like it. It might seem too sweet for me, but somehow I like the idea. And the gameplay was decent. Anime -- not so much, and of course they went with the most obvious pairing. I would've been very surprised if they'd chosen Nakajima x Keita.
Count x Albert, Franz x Albert
It makes me feel like a big perv, but I really love the idea.
Get Backers #**
Ban x Ginji
Lindow x Lenka
It's classic. 'nuff said.
The biggest mistake by Sunrise so far. I hope their next Gundam wouldn't be so ludicrous.
UPD 2015 How wrong I was... And right after that Gundam AGE happened. Thankfully, Sunrise pulled their shit together after that.
Gundam Build Fighters
Reiji x Iori Sei, Tatsuya Yuuki x Iori Sei, Kamiki Sekai x Kousaka Yuuma
Gundam: Iron-Blooded Orphans
Orga x Mikazuki
Gundam SEED/Destiny #*
AsuKira (Athrun x Kira), Dearka x Yzak
Gundam Wing ########*
This practically dead fandom is still (and, I suspect, will always be) one of my favourites.
Tohru x Tohru
It's not actually my fandom... but what Vega-sama wants Vega-sama gets ^_^ And I don't really mind the characters.
KageHina, AsaNoya, KuroTsuki, Ukai x Takeda, Sawamura x Sugawara, Kuroo x Sawamura, Kenma x Hinata, Bokuto x Hinata, Akaashi x Kageyama
Everyone x Everyone
Haru o Daiteita
Katou x Iwaki
Hero Heel #
Sawada x Minami,
Manga fandom. It's one of my idiotic dreams to see it as anime one day.
Hikaru no Go #*
HikaAki (Hikaru x Akira), WayaSumi (Isumi x Waya)
HikaGo, HikaGo, HikaGo. What can I say about it? It's Go, it's Sai, and it's totally lovely.
Hoozuki no Reitetsu
Hakutaku x Hoozuki
The general universe rather than any particular pairings, but the idea of HakuHoo is just hilarious.
Ikoku Irokoi Ronamtan
Al x Ranmaru
Inugami-san to Nekoyama-san
My very first yaoi fandom. I'd still love to read a nice SeshxInu story, but somehow over the years the good authors just died out. Sad.
Sugizo x anyone really ^_^ As long as they're both male ^^" Sugizo x Kawamura Ryuichi, Sugizo x Yoshiki (or Yoshiki x Sugizo more like ^^"), Gackt x Sugizo,
It was so entertaining to be in this fandom. It was so full of crack that you started seeing pink elephants after a couple of fics. And Sugizo aka Walking Porn aka Legs will always be my favourite. Among others.
UPD 2015 And I haven't even mentioned that all of the above was about Russian JRock fandom. English fandom is quite different...
Junjou Egoist (Nowaki x Hiroki)
Junjou Egoist is sweet and amusing. Everything else -- not so much.
Kuro x Shiro, Saruhiko x Misaki
Yuki x Sakuya
Searching yaoi in a romansu fandom is nightmare for a fujoshi.
Leo x Will
Shoukatsuryou Koumei x Rikuson Hakugen
Kyou kara Maou! ######
ConYuu (Conrad x Yuuri), Shinou x Daikenja, Berias x Saralegui
I love the frist two pairings. And I love Sara-the-Ishida-character.
Hiroomi x Akihito
Kyoukai no Rinne
Rinne x Juumonji
Craft x Prince
I'm more of a fan of the Troll Prince than any pairings here.
canon, Saotome x Kuroi (or is it canon too?)
Dantalion x William
Maria-sama ga Miteru
Sachiko x Yumi, Sei x Shimako, Shimako x Noriko, Rei x Yoshino
Seki Toshihiko x Ishida Akira was nice. More than nice actually. But the fandom itself just wasn't all that interesting.
Mirage of Blaze
Naoe x Takaya
Akise Aru x Yukki
Ishida Akira and yandere vs. yandere bitchfight. Erm, yeah. That's about it.
Mugai x Jinbei
Me and my obsession with rare fandoms and pairings. This one just didn't sail. Unfortunately.
How can I resist Ishida!yaoi? That's right, I can't.
Natsume Yuujinchou ###
Natori x Natsume, Tanuma x Natsume
How can I resist Ishida!yaoi? That's right, I can't.
Mireille x Kirika, Chloe x Kirika, Silvana x Mireille
Loving this fandom from afar. I don't want to spoil my view of the characters by reading something I won't like.
Yato x Yukine
Saitama x Genos
Kougami x Ginoza, Shion x Yayoi
Rampo Kitan: Game of Laplace
Akechi x Kobayashi, Hashiba x Kobayashi
Ranma 1/2 #
Ranma (male) x Ryouga
Ah, another 'old fart' fandom. I tend to love these.
Narumi x Hibiki
Just... don't ask.
Yuda x Shin, Ruka x Rei, Kira x Maya
Not the best Ishida!role, but it was nice enough.
83 (Hakkai x Sanzo), Dokukakuji x Gojyo, Homura x Kougaiji, Nataku x Goku, Tenpou x Konzen
83 is one of my two all-time OTPs. I love everything about the pairing, from dark and depressing past to dog-like loyalty and trust. And said loyalty and trust kinda set standard for everything I read in other fandoms. Which makes me inadequately bitchy about partner betrayal. (that and het are two easiest ways to make me hate you forever)
UPD 2015 Not quite so radical anymore but... still 83 is one of my OTPs
Konzen x Tenpou, Nataku x Goku
It took me a long time to get here. I was afraid of the tragedy part so didn't even attempt to read it, but then Gaiden OVA happened, and well... Minekura-sensei is a genius, and Ishida is still Ishida.
Samurai 7 ###
Kanbei x Kyuuzou,
How could I like Katsushiro? No, really. How could I like Katsushiro?
Samurai Champloo #
Jin x Mugen
Entertaining and a real treasure if you're into power-play-related kinks.
Self-yaoi and Ishida Akira. Yep, I'm a perv.
Goto x Masayoshi
Crack, crack everywhere :D
Everyone x Everyone
It... didn't happen. Nope. ^^"
One word: twincest. And not 'we're so alike' twincest that's plain boring, but evil!twin vs. good!twin.
Ozaki x Muroi, Tohru x Yuuki
One of the newer additions. We'll see how the fandom will build.
Shin Sekai Yori
Saturu x Shun, Maria x Saki
I liked the general idea more than the pairings, although it was nice to get both yaoi and yuri in canon, especially with the way the relationships were shown -- just something normal, nothing strange or extraordinary about it.
Shingeki no Kyojin ###
Ereri, Jean x Marko
Well, not exactly major anymore... but I still have a lot of warm memories from this fandom.
Shoujo Kakumei Utena **
Utena x Anthy, Juri x Shiori, Touga x Saionji, Akio x Touga, Akio x Touga x Saionji
Shoujo mindfuck classic. Someone called it 'Evangeloin for girls'.
Skip Beat! ###*
Ren x Shou, Reino x Shou, Ren x Reino, Kyouko x Kanae
Ah, I anpicipate all of the bricks and tomatoes coming my way when I finally finish Coming Out... It's a Ren x Shou, Kyouko x Kanae fic, and not what you might've thought ^_^ Seriously, breaking the main pairing in a romansu to turn it into yaoi and yuri? Someone might kill me ^______^
UPD 2015 Yet again, didn't happen. How many fics have I dropped...?
Xelloss x Zelgadis,
XelZel is my first (of the two) OTP of all time. I talked so much about it over the years that I don't have words anymore.
Soul Eater Not!
Meme x Tsugumi x Anya
One name: Ishida Akira. I don't even remember the pairings I read with Eyes Rutherford. Shame on me.
Star Driver ##
Sugata x Takuto, Head x Sugata
Minato x Nanami, Sora x Sunao
I might've gathered every possibly Ishida!fandom. Except one that won't be mentioned here. Ever.
UPD 2015 Well, not every possible fandom as it turns out... But yeah, that one is still unmentionable.
Haruka x Kantarou
Koutetsu x Barnaby, Rock Bison x Sky High, Lunatic x Origami (thanks, Forumverse)
Togainu no Chi
Akira x Keisuke, Shiki x Akia, Shiki x n, Arbitoru x Shiki
Another new addition. I have to admit, I was more than a little dubious about this one. But I gave the game a shot, and it's not as bad as I thought. Gameplay is less handy that in Gakuen Heaven, but the story is not bad. Anime is crap though, but that's another story altogether.
Hideyoshi x Kaneki
Wolfwood x Vash, Vash x Knives, Knives x Legato, Legato x Wolfwood
See a pattern here? ^_^
Luka x Yuki, Luze x Luka, Reiga x Takashiro, Hotsuma x Shusei
UPD 2015 Didn't sail. End of story.
Valkyrie Drive -Mermaid-
Tsume x Toboe, Tsume x Kiba, Kiba x Hige
Osamu x Yuuma
Am I the only one who sees that? Really?
Kawachi x Azuma, Suwabara x Kawachi, Kuroyanagi x Kanmuri, Pierrot Bolneze x Azuma, Meister Kirisaki x anyone
Sei x Moichi, Rin x Sei
I loved the dorama and spent weeks hunting for Sei x Moichi and Rin x Sei, but the fandom is virtually dead. Alas.
Hiroya x Akira
Young Black Jack
Kiriko x Hazama, Hyakki x Hazama
TouMaki, SanSaka, T2, FukuKin, AraSaka, ShinAra,
"Thank" you, Yowapeda. Now I own an MTB bike and am thinking of an upgrade already, preferably a Giant Invite CoMax, Giant Brava SLR or Trek Silque SSL and Trek Lush Carbon 27.5 (yeah, dream on, Kaworu)
Zankyou no Terror
9 x 12
Zetsuen no Tempest
Mahiro x Yoshino
Tyr x Dylan
Me and my love for damn obvious rare pairings strikes again. Why the frell is it always Harper? >.<#
Doctor Who (Classic)
Someone called 5/Turlough a 'small black dress of the DW fandom', and I can't help agreeing with that
Doctor Who (2005) #
10/Jack Harkness, 9/Jack Harkness, 12/Jack Harkness, 12/Turlough
I just have to add this one here. The only reason I didn't in 2010 was because I don't have any pairings there.
Snupin (Snape/Lupin), Sirry (Sirius/Harry),
Major obsession for a long time. I had to leave after HBP, because marrying Remus and sending away Severus was plain cruel. I have a personal vendetta against momma Rowling after that. Oh, and there's never enough curses for Thewlis as Remus. He's a frelling Paul Verlaine, not Remus. Yes, sure, he was a perfect Paul Verlaine, but Remus is not a whorish, pretentious... something. I don't even have a proper word for him.
UPD 2015 I'm 'back together' with Snupin and Sirry, if only as 'comfort food' when I don't want to read anything else.
Life on Mars (UK)
Sam Tyler/Chris Skelton
John Sheppard (Stargate Atlantis)/Patrick Jane, Walter Mashburn/Patrick Jane
If I could get away with it I would add Neil Robertson (snooker player)/Patrick Jane >D
Poltergeist the Legasy
Queer as Folk
canon ^^" Seriously? More Ben/Michael than Brian/Justin. Oh, and my crack OTP of DOOM -- Brian Kinney/Lex Luthor (Smallville) >D
Will/Henry, John Druitt/Nikola Tesla, John Druitt/James Watson, Nikola Tesla/Will
I have to go fic hunting one of these days...
UPD 2015 Dead fandom wtf
Not so much after S3, but I still wouldn't mind reading a fic or ten.
Peter Parker/Harry Osborn
Do I have plausible deniability? No? Okay then.
Stargate Atlantis ##
McShep (McKay/Sheppard), Lorne/Zelenka, Ronon/Carson, Cam Mitchell/John Sheppard
Stargate SG-1 ###
Jack/Daniel, Cam Mitchell/John Sheppard
Jack/Daniel was my major obsession long before I knew what yaoi (let alone slash) was, and for years -- years! -- I thought I was the only perv who could see them together. Turned out I was spectacularly wrong. So now I have three OTPs of all time instead of two.
It turned out to be such a disappointment it's not even funny.
Wincest (do I really have to explain this? ^_^), Gabriel/Castiel
I haven't really been in the fandom since season 3 started airing, but Gabe is slowly tugging me back...
UPD 2015 Erm... Do I have to even go there?
The L Word
Francesca/Marina, Jodi/Bette, Lara/Dana, Joice/erm... someone? ^^"
any male/Armand/any male
J2 (see Wincest), Michael Rosenbaum/Tom Welling, Michael Rosenbaum/Jensen Ackles
UPD 2015 My interest died along with logic in Spn.
