Raditz is a Saiyan who initially comes to Earth to check on the progress of his younger brother, Kakarrot ( Goku). After discovering that rather than wiping out the inhabitants of Earth, Goku has been aiding them, Raditz decides to kidnap Goku's son, Gohan, to try to force Goku to join him and destroy the earthlings as he was originally supposed to do. This action leads to the demise of both Goku and Raditz as Piccolo fires his new Special Beam Cannon attack at Raditz while Goku is restraining him from behind, Goku sacrificed himself in order to rid the world of his evil brother. Before he died he used his scouter to send a messege to his fellow Saiyans Nappa and Vegeta to inform him of the magical Dragon Balls on Planet Earth which could grant wishes.
When Vegeta and Nappa arrive on planet Earth it is revealed that Raditz's power level was 1200, the same as certain batches of Saibamen.
Raditz has appeared as a playable character in most of the newer Dragon Ball Z fighting games including the Budokai games, the Budokai Tenkaichi games and Dragon Ball Z: Burst Limit. He was not however in the roster for either of the Shin Budokai games for the PSP.
Being Goku's brother, Raditz is also the son of Bardock, Gohan and Goten's uncle and Pan's great uncle.
As with all other Saiyans in Dragon Ball Z, Raditz name in based on a vegetable, in this case a radish.
Raditz is a tall Saiyan, at around the same height as Nappa
and considerably taller than his brother Goku. He is known for his extremely long, wild black hair as it is the longest natural hair of anyone seen in the Dragon Ball Z
franchise. The thought of him transforming into a Super Saiyan 3 would be pretty damn crazy. He has brown and black Saiyan Armor
and wears a green Scouter
. His armor is very similar to Nappa's. Raditz also wears red/brown bands around his left arm and left leg.
