I've read many mangas but cannot recall alot of the names....most of them were half-translated.
So:
Akira (Goes into greater detail than the anime and it has more characters and another sub-plot with Tetsuo's empire.)
Lupin III (Hilarious.
)
Ranma 1/2 (Same with Lupin.)
I'm hoping to read Naruto and the first Trigun volume soon.
