anime then it would probably be Gundam Wing or Guyver. Manga (excluding the mainstream 3) would probably be D. Gray Man or Tsubasa Chronicles.

I'm ashame to say.......... none. Why.......I'm very cheap........and poor.
IF YOU WANT TO KNOW WHERE I'M FROM TAKE A LOOK HERE MY FRIEND:Spoiler!
I don't like to buy them, unless it's already completed and compiled into one book. English translation of course, and by complete I mean, having all the chapters and extras.
It's highly unlikely though, :p
My first manga was 'Death Note'. I got hooked into the first 10 episodes of the anime and I couldn't wait a week for the next episode so I read all the manga in like 2 days. First manga I bought was 'Full Metal Alchemist', loved the anime and I saw the first 15 volumes at a anime convention...I just couldn't resist!
Black Cat was my first manga I think. Either that or Dragonball
