It has been some years now since the release of the original Buu arc however; this is the digitally remastered Dragon Ball Z Kai.
Dragon Ball Z Kai is essentially the HD version of Dragon Ball Z, which also has no filler, as the original episodes were all made in the early 1990’s.
Although, many fans still prefer the original animation, as well as watching all the filler but for those who don’t and love Kai, part one of the Buu arc is now finally available on DVD.
In part one we see that seven years have passed since Gohan victory the end of the Cell Games, with Goku still dead. Gohan has given up on his training and has grown quite a bit, as have all the characters (KRILLIN HAS HAIR).
Gohan enters high school, Krill and Android 18 have a child, Yamcha has given up on fighting, Vegeta can transform into a Super Saiyan two and the Goku has a new son in Goten. Yes, a lot has changed as the world is now in peace however, that won’t last long.
