The original manga of Astroboy was published in an English language edition by Dark Horse Comics Company from 2002 to 2004. There were 23 issues altogether presented in the form of small paperback books and they read from left to right according to western style as opposed to the way books in Japan read from right to left. Another point of interest is that with the exception of Astroboy himself, all the characters are referred to by their original Japanese names. Doctor Boynton-Doctor Tenma. Professor Elefun-Professor Ochanomizu. And so on.
