I already edited in the answers
here, but I should probably say a little about it, so...
1. Air Gear
spiralsword &
xenylamine both got this first try. It was kind of obvious, really.
Character:
Bandou ~ The first time I saw him was when I was yanking pages from mangarun.com, & I hadn't been reading the conversation at all for about 3 volumes worth of material. I thought he was Gaara, & my obsessive love for him developed from there. Though I have no idea why he & Sano are the only Behemoth members who I refer to by their last name.
Pairing:
Kazu/Emily ~ Everybody loves Kazu/Emily. Ask anyone at all in the fandom. They are just too cute for words.
2. Naruto
Character:
Kimimaro ~ I think his character had a lot of potential, & it was sad when he died. He was given more depth in the anime (with the cages & the coup) but I'd like to've seen more of him in the manga as well.
Pairing:
Gaara/
Naruto ~ Gaara so totally beats out Sasuke as Naruto's Mr. Right. & while Sasuke is off trying to kill his brother (& threatening to kill Naruto, too), Gaara is trying to become a Better Man after getting beaten into the ground by Naruto.
3. Digimon Adventure
Character:
Hikari ~ She was cute in season 1, & so was Tailmon. And then she was back in season 2, & still cute but this time a little older. *Hugs*
Pairing:
Takeru/Hikari ~ Is it okay to admit that I was shipping them in season 1 as well? Even though they were eight? Takari is almost as sweet as Kazu/Emily, & that's saying a lot. Daisuke definitely doesn't approve, though ;P
4. Digimon Frontier
Character:
Kouichi ~ The whole good twin-bad (long-lost) twin thing is really old, I know, but Kouichi's not so bad really. & he switches sides in the end, and then dies to save his brother. But I loved him even when he was almost-evil (which is strange, 'cause I hardly ever like the evil characters).
Pairing: Kouichi/
Takuya ~ Well "he's the one" really cinched it for me, but mostly it's just because I'm rather shallow, & they're cute together (plus, I like Kouichi better than Kouji).
5. Code Geass
Character:
Suzaku ~ He is totally In Denial about the reasoning for everything he's ever done in his whole entire life. And he still manages to be really, really nice. & the thing with the cat! *Fangirls*
Pairing: Suzaku/
Lelouch ~ Suzaku is the only person who Lelouch will actually admit that he never intended to use the geass on in his grand scheme to kill the Emperor & find out who killed his mum. Now, isn't that sweet?
6. Torchwood
Character:
Mary ~ She was just too awesome for words when she first appeared. And then Jack killed her. Damn him.
Pairing:
Tosh/Mary ~ Canon femmeslash? Even though I like hardly any femmeslash pairings? But they are both so awsome, & as Gwen said, "love suited [Tosh]".
7. Doctor Who
Character:
Jack ~ He's more awesome in DW than in Torchwood, methinks. Especially with the Ann-droid on the Gamestation.
Pairing: Jack/
Doctor/Rose ~ I don't know. They just don't seem to fit any other way. And I like Martha well enough, but she's just... not Rose.
8. Harry Potter
Character: Regulus ~ RAB! I so wish that JKR had decided to reveal that he was actually still alive in book 7, but apparently not. Poor Reg.
Pairing: Harry/Blaise ~ At first it was more like a... complications-free version of Draco/Harry (which I have never really liked, so don't ask me how that figures), but the more I got into it, the more Blaise began to develop his own character, & I got hooked. Plus,
potent_serpent is a lovely place to hang out~ ^^
9. The Dark is Rising
Character: Bran ~ It was the whole Welsh-albino-&-son-of-King-Arthur thing that got me. And Cafall.
Pairing: Will/Bran ~ They are In Love; I am convinced of it.
See? I even wrote an essay on the subject. 10. Bleach
Character:
Ulquiorra ~ He was kickarse when he first appeared, & remained kickarse throughout.
Pairing:
Ichigo/Tatsuki ~ Did anyone else notice that they both wear badges with three stars on them? Just those two, even though Tatsuki's a pretty minor character (thus far). & those dojo scenes were the cutest part of the entire series, imho.
