Dragon Ball Z Kai/Episodes

Dragon Ball Z Kai (known in Japan as Dragon Ball Kai) is a revised version of the anime series Dragon Ball Z, produced in commemoration of the original's 20th anniversary. Produced by Toei Animation, the series was broadcast in Japan on Fuji TV from April 5, 2009 to March 27, 2011, and later continued with the final story arc from April 6, 2014 to June 28, 2015. It features remastered high definition picture, sound, and special effects as well as a re-recorded voice track by most of the original cast. As most of the series' sketches and animation cels had been discarded since the final episode of Dragon Ball Z aired in 1996, new frames were produced by digitally tracing over still frames from existing footage and filling them with softer colors; thus reducing visible damage to the original animation. Some frames were selectively cropped, while other frames feature new portions added to scenes that were hand drawn to conform to the designated picture ratio. Much of the material from the Dragon Ball Z anime that was not featured in the Dragon Ball manga has been left out in Kai; reducing the total episode count from 291 to 159. The first Blu-ray and DVD compilation was released in Japan on September 18, 2009, with individual volumes releasing monthly as well as Blu-ray box sets.

In 2010, Funimation licensed Kai for an English-language release in the U.S. Funimation's dub of Kai features most of the voice actors from their in-house dub of Dragon Ball Z (though also several re-casts), as well as a more faithful adaptation of the Japanese dialogue than their previous dub. The series aired in an edited format on Nicktoons, in addition to The CW's Toonzai block (later renamed Vortexx). Furthermore, Funimation has released bilingual uncut Blu-ray and DVD volume and season box sets of the series in North America.

On May 25, 2014, Funimation and Adult Swim announced that the uncut version of DBZ Kai would be airing on Toonami starting November 8, 2014.

As of 2016, only the first 4 seasons (98 episodes) of DBZ Kai have been released to DVD and Blu-Ray in North America by Funimation.
