Five years after winning the World Martial Arts tournament, Gokuu is now living a peaceful life with his wife and son. This changes, however, with the arrival of a mysterious enemy named Raditz who presents himself as Gokuu’s long-lost brother. He reveals that Gokuu is a warrior from the once powerful but now virtually extinct Saiyan race, whose homeworld was completely annihilated. When he was sent to Earth as a baby, Gokuu’s sole purpose was to conquer and destroy the planet; but after suffering amnesia from a head injury, his violent and savage nature changed, and instead was raised as a kind and well-mannered boy, now fighting to protect others.
With his failed attempt at forcibly recruiting Gokuu as an ally, Raditz warns Gokuu’s friends of a new threat that’s rapidly approaching Earth—one that could plunge Earth into an intergalactic conflict and cause the heavens themselves to shake. A war will be fought over the seven mystical dragon balls, and only the strongest will survive in Dragon Ball Z.[Written by MAL Rewrite]
The U.S. version is a dubbed alternative version of the Original Japanese anime. For example, blood has been taken out, beer is called root-beer, dead is called “Another Universe” and people emigrate before the destroying of cities. (Source: YouTube movie – Anime History Day)
The U.S. version edited and compiled the original for a reduced episode count of 276, instead of the original 291. The proper episode count was later restored on the uncut “Orange Brick” Season Set releases by FUNimation Entertainment released from 2006 to 2009. Additionally, the North American “Orange Brick” Season Sets as well as the Season Set Blu-rays crop the show from its original 4:3 aspect ratio to 16:9. The only complete 4:3 release ever released in English were the Dragon Boxes which have long since gone out of print.
