Alternate versions

The US version from 2004-2006 is heavily edited over the Japanese version. All blood is removed, all guns are changed to non-lethal weapons (pop guns, squirt guns, etc.), all alcohol is changed to juice, and all cigarettes are changed to lollipops, among other changes. When Funimation took over the dub production in 2007, it was a lot more faithful to the original.

Three English dubs exist, one was done by 4Kids Entertainment and ran from 2004-2007 which was canceled due to production costs, the Funimation Entertainment dub that has been in production since 2007, and a lesser known English dub produced by Odex Ltd, that only consists of the first 104 episodes which aired in the Southeast Asian television market.
