I think I'm answering these just for Fushigi Yugi. XD And perhaps Ranma, because I've read that too. And maybe Boys Next Door. And maybe some of the yaoi/shounen-ai stuff I've read.
-Which characters/villains/fighters/catgirls (whatever you can think of) are your favorites and why ?
Uwaaa, definitely Tasuki because he's just great. XD He's like, funny, and stuff. And also hot. But mainly funny. And doesn't like Tamahome. Which is why it's so fun to pair them. Why do I keep splitting my sentences?
-Which characters you think are the most attractive/sexy/bishie/cute/etc?
Lawrence (Boys Next Door), Ryoga (Ranma), Tasuki, Nakago, Amiboshi and Tamahome (Fushigi Yugi). OH AND OMG RABI~EN~ROSE. <3 I'd forgotten about DiGi Charat!
-Which characters you think are the strongest/dumbest/smartest/etc?
Strongest... Nuriko. X3 He's so strong~ Dumbest is Miaka (or maybe Ryoga!) for obvious reasons. Smartest... Hm... Maybe Chichiri? Or Mitsukake? I'm not sure.
-Which character you want to be/replace/make real/etc?
I want to BE? o_o; I'm not sure. Maybe Miaka, or Shampoo... Nuriko's spiffy, but I wouldn't want to be him - he's all lovey-dovey over Hotohori, who likes stupid Miaka. OH WAIT NO I want to be CHIRIKO! X3 So cute~
-Which characters are your least favorite and why you dislike them?
I don't like Yui (FY) because she's all fickle and stuff, and won't listen to reason. Oh, and Genma (DiGi) because it's annoying. x_o; OH AND MIAKA. She's annoying too.
-Which pairings, real or otherwise, do you want to see/like?
TasukixTamahome, SuboshixAmiboshi (shut uuuuup), NurikoxHotohori, ChichirixTasuki (how COOL would that be?!), RanmaxRyoga (lmao).
-Which animal/creature/mecha/etc are your favourites and why?
MITSUKAKE'S CAT. <3
-Which weapons/powers/abilities you find to be the coolest/lamest/flashiest/etc and which ones you want?
I want Tasuki's talisman thingies! I'd write dumb things like 'TasukixTamahome' or 'something entertaining'. XD;
-Which character you'd like to marry/be trapped on an island with/go on a date with/team up with to save the world/kill or humiliate/steal from/bake cookies with (whatever you can think of)?
Marry: Nobody. I'm not the marriage type, and I prefer to pair characters with one another rather than myself. X3
Trapped on an island: HUAN LANG. That's Tasuki. XD He could write 'boat' and 'oars' on his talisman things. AND BURN THINGS WITH HIS HARISEN.
Go on a date with: Nuriko. HE'S SO COOL~~
Team up with to save the world: Chiriko and Puchiko! We can be cute together! ^0^
Kill: Miaka. x_o; Or Yui. Or Genma.
Humiliate: Tamahome. X3 Humiliation is fun!
Steal from: TAMAHOME. XD "I had one more coin, I know I had 312!"
Bake cookies with: Chichiri. X3 He's so spiffy, isn't he~?
