Raditz is a character that appeared in only few episodes in season one of Dragon Ball Z. Raditz is the brother of Goku, and is the eldest son of Bardock.
Raditz had traveled to Earth to check on his brother Kakarot, as he he had been named by in the planet Vegeta. However, Raditz was disappointed to find out that Goku's programming had been erased, and Goku had instead of used his powers to take over the world as his programming had been set to, he had helped the people of Earth. Raditz took Gohan as a hostage, and warned Goku that if he didn't join him, he would kill his son. Goku would not join Raditz, Piccolo and Goku united to battle Raditz.
Gohan watched the battle from inside the Saiyan's space ship. During this, Gohan's rage is unleashed, and attacks Raditz with one single blow, enough for Goku to put his opponent on a head lock. Piccolo takes advantage and blasts at both of them with the extremely powerful move known as the Makankossapo, killing both Goku and Raditz. Just before Raditz died, Piccolo told him that Goku would live because of the seven magical Dragon Balls. Raditz surprised him by telling Piccolo that he had transmitted this information to two more powerful saiyans ( Nappa and Vegeta), and that they would arrive in search for the Dragon Balls in one year.
When Goku reached the checkout station and was preparing to jounrey to King Kai's planet for training, Goku asked King Yemma what became of his brother's soul. Yemma states that Raditz caused a lot of trouble when he arrived and King Yemma had to fight him order to send him to hell. Yemma used his patented Yemma lock to subdue Raditz. Once Goku reached King Kai's planet and began his training King Kai invited Raditz to his planet for a chance at defeating Goku, but he was unable to defeat his him and sent back to hell.
Later Raditz learned of King Yemma's fruit and defeated the trolls guarding the fruit. Goku was sent with Gregory and Bubbles to stop Raditz in hell. Raditz planned on eating the fruit and becoming more powerful than King Yemma. Raditz was once again defeated by Goku.
When Gohan was looking for the final Dragon ball to revive his father he had to seek help from Fortuneteller Baba and since he could not pay her fee Gohan was forced to fight her fighters like his father had to do when he was younger. Gohan's final opponent was Raditz who was revived for one day by Baba as a test of Gohan's strength. Raditz was defeated by his nephew.
Powers and Abilities
Raditz at the start of the series was able to outpace both Goku and Piccolo at the same time and utterly dominate them both in battle. In realtion to the rest of the Saiyan army and Freeza's World Trade organization, Raditz is a low level solider who gets little respect and is barley more powerful than the Saibamen used by Nappa. Even so Raditz is capable of moving faster than the human eye can track, fire energy blasts, fly under his own power, and smash stone with his strength. Like most low class Saiyans Raditz becomes vulnerable when his tail is grabbed.
