List of Recommended Manga

[Fortuna]

D.Gray-Man
Gintama
Kaiji

[dcspyro]

Naruto, Tenjou Tenge, Death Note, Hellsing. All good ones that I have read

[Takeshi]

Try One piece or Hajime no Ippo over 900 of good fights and funny moments

+1000

Two of my favourite mangas. I can also recommend Soul Eater, Fairy Tail and Psyren.

[Umi-chii]

If you like GB's genre, you'll most likely like Wild Adapter too, though it has a more serious atmosphere than GB. It's from the author of Saiyuki, Kazuya Minekura. If you want something crazier and funnier, go for Gintama. It's a really good series lol.

Of course there's the big three... there's also Katekyo Hitman Reborn, Fairy Tail (which I really rec!), D.Gray-Man, Prince of Tennis, Tenjou Tenge (THIS you must at least try).

There are also some mangas lately that are borderline between shoujo and shonen, like Pandora Hearts and 07-Ghost. Both are really great and has a very intricate plot. I highly recommend them both.

I agree with a lot of my predecessors about their choices! Mine woud be: Katekyo Hitman Reborn, Wild Adapter and a little more gloomy would be Hellsing and Blood the Last Vampire 2000.

[Asterisk]

wow, lots of good stuf here

I just add 3 of my favourites :

- The Breaker ( Martial )
- Gantz ( SF )
- History's Strongest Deciple Kenichi ( Martial )

And a special mention to Fairy Tail and Mysterious Girlfriend X 

Agree with HSDK.

The series focus' more on real human ability and less of complete fantasy powers (though there still is a lot of crap that would be physically impossible). It's got a good balance of comedy, slight romance and action.

[civer]

you should give death note a try.
Or if you re more into action try samurai deeper kyo (it doesent have a deep story, but it certainly is entertaing)

[civer]

for these who like psychological: lolipop or a bullet -- its not very famous, but its really good. The characters are very real in every way and, while the story is very sad, its not to far fetched
