Raditz

"I have a little something that will surprise you! " — Raditz before going Super Saiyan in Evil Reborn

Raditz (ラディッツ, Radittsu) appears in Dragon Ball Z, Dragon Ball GT (cameo) & Dragon Ball Z: Evil Reborn.

Pre-Evil Reborn
While Goku cries out in pain with Piccolo helplessly watching, a power suddenly erupts and Raditz's spacepod explodes. Just as Raditz prepares to kill Goku, an enraged Gohan emerges and [http://dragonball.wikia.com/wiki/Leave_My_Daddy_Alone! flies straight into Raditz's chest], seriously injuring him. Raditz, incensed and in awe of the small child, and whacks Gohan across the field, and limps over to Gohan, preparing to kill him, in fear of Gohan's power, which he complimented as he approached. Before this can happen, however, Goku grabs Raditz from behind in a full nelson, giving Piccolo enough time to power up another Special Beam Cannon. Raditz, fully aware that the beam will be enough to finish the both of them, implores Goku not to sacrifice himself for "these Earth dogs" and let him go, but Goku refuses. Piccolo fires the Special Beam Cannon and hits both Raditz and Goku square, mortally wounding both.

As he lies dying, spitting blood and suffering on the ground, Raditz genuinely acknowledges Goku's death (as well as his own), but Piccolo tells him about theDragon Balls, that will revive Goku shortly after the wish is made. Raditz, however, retorts that his scouter is also a transmitter, and his two Saiyan comrades have heard everything and will come for the Dragon Balls to wish him back. Laughing his head off, Raditz is finished off by Piccolo, and dies shortly before Goku does so. Using his scouter to transmit Piccolo's message, Raditz calls for help from his two fellow Saiyans, Nappa and Vegeta, who eventually journey to Earth to gather the Dragon Balls, not to revive Raditz (as Raditz believed), but for immortality. In the Other World, Raditz attempts to fight King Yemma, who overpowers him and sends Raditz to Hell.

After Goku dies, Bulma and Krillin remove Raditz's scouter from his corpse (which remains unseen). Bulma modifies the scouter so it can display numbers rather than the alien symbols that are used by Frieza's forces. The scouter later explodes when Goku powers up during his fight with Vegeta.

Evil Reborn
In Dragon Ball Z: Evil Reborn, Raditz reappears shortly to fight Goku and Vegeta, eventually, Raditz goes Super Saiyan 4 and calls in the help of an also SSJ4 Nappa but loses anyway.
