I swooned at half your list. ESPECIALLY AT SEBASTIAN.
I love Koga from Inuyasha! His voice is so sexy! Honestly, if I made a list, I couldn't stop at a Top Ten. I'd just keep going and going and going. I'll see about making one though so I can share my love.
Okay, the only one I have right now is Fullmetal Alchemist so I might try and watch it. My friends kinda told me to watch it but I was just distracted with other animes like One Piece, Fairy Tail, Ao No Exorcist and a lot more. I have like a ton of anime in my hard disk that I haven't watched. LOL!
@ Vicious Vengeance Alucard and Walter are from Hellsing (watch it because it's honestly amazing) Sebastian is from Black Butler Greed, Pride, Wrath, and envy are from full metal alchemist Howl is from Howls moving Castle :)
