Raditz

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 o check on his brother Kakarot, as he he had been named by in the planet vegeta. However, Raditz was dissapointed 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, and that they would arrive in search for the Dragonball in one year.
