Dubbing History
The series was initially licensed and dubbed by Manga Entertainment as The Heroic Legend of Arislan and released on VHS in the United Kingdom. Manga only dubbed the first 4 episodes (those being the only episodes released at the time of dubbing).

When the series was later released in the United States by Central Park Media, Episodes 5 and 6 were dubbed using their own New York-based cast and released as Heroic Legend of Arslan: Age of Heros. This caused a lot inconsistencies with the original dub, including utilizing different translations and names.
