Alternate versions

In Spain and other countries of Latin America, the original release in the '90s had a different intro, with scenes from the movie "Abel" and a song in Spanish (which wasn't a translation of an original but instead a translation of the French intro from "Les Chevaliers du Zodiaque").

The U.S. release changes the blood color, from the original red, to green or grey in different scenes (this at least happens in the first episodes).
