GOKU: Huh?!
KRILLIN: Wha...Wha's he talkin' about? And who is he?
RADITZ: Has something on this world DISTRACTED you, Kakarrot?? Your DUTY was to EXTERMINATE this species! What game have you been playing at!?
KRILLIN: Look, Pal...I don't know who you are, but...GO HOME! Scram! Shoo! Th' LAST thing we need is drunks like YOU hangin' around th' place--
GOKU: KRILLIN!!! DON'T GET ANY-
RADITZ SMACKS KRILLIN WITH HIS TAIL SENDING HIM FLYING AT KAMEHOUSE
GOKU: KRILLIN!!!
KRILLIN IN THE RUBBLE
KRILLIN: PWIK...PWIK...
GOKU AND RADDITZ
GOKU: WHY-Y-Y, YOU...!!!
GOKU, MASTER ROSHI, BULMA: A-A TAIL...!?!?
GOKU: Y-you've got...a TAIL...!! A tail...Just like I usta have...!!
RADITZ: Heh heh heh...and so, now that you know who I am--
GOKU: B-But, who ARE you...!?
RADITZ: You mean...you STILL don't...!? Impossible! You could NEVER have forgotten me...or our mission! What's happened to you, Kakarrot!? Did you take a blow to the HEAD!?
GOKU: Look, I don't know who this "KAKA" guy you're talkin' about is...But I'm SON GOKU!!
RADITZ: You're INSANE!! It MUST be a result of brain damage!!
GOKU: ...Okay! 'S true, I've got a scar maybe I DID hit my head once...But I was too little T' remember!
RADITZ: Damn you, but that WOULD explain it...
GOKU: Explain WHAT!? What th' heck are you TALKIN' about!?
MASTER ROSHI: Goku, your granpa, Son Gohan, he...he told me once that he found a baby in the woods, a baby with a TAIL. He was a WILD one, too, that baby...One what couldn't be tamed by anyone...THAT IS, until that baby fell down a gorge one day, hit his head, and pretty near died. But he was a TOUGH Li'L monkey! He pulled out've it, an' ever after, he was th' SWEETEST Li'L thing you'd ever hope T' see...
RADITZ: "SWEET" !?
GOKU: An' that baby...was ME!?
MASTER ROSHI: ...He was. Is.
BULMA: ...B-but what's that MEAN? Who's THAT guy? and what's he got T' do with GOKU!?
GOKU: ...ANSWER ME!! Who ARE you!?
RADITZ: Take warning-- if there is ANY trace of memories in there, I WILL find a way to reveal them!
RADITZ: SHRRRP *His tail re-coils around his waist*
RADITZ: We need you BACK, Kakarrot..your PEOPLE need you back!
KRILLIN: *crawling out of rubble* UNH...OO-WAH~
GOKU: Krillin! You okay--!?
KRILLIN: Y-yeah...But I dunno how...Be CAREFUL, Goku...He's more 'N human!
GOKU: Yeah, I noticed. Just lookin' at him makes my hair stand on end...An' that's never HAPPENED T' me before!
RADITZ: That is because you and I...We are the SAME!! YOU ARE NO EARTHLING! You are a SAIYAN WARRIOR...A member of the most POWERFUL RACE in the UNIVERSE!!
MASTER ROSHI: N-No...It...It CAN'T be...!!!
RADITZ: And I am RADITZ...Your older BROTHER!!!
KRILLIN: G...G...G...G...G-Goku's got a BROTHER...!?
BULMA: And he's...an ALIEN...!? N-no way...!!
GOKU: YOU LIAR!! Take it BACK!!
KRILLIN: If Goku's an ALIEN, why's he HERE!?
RADITZ: Heh Heh Heh... You may be sorry you asked, but the answer is a simple one. We are a warrior race...and an entrepreneurial one! We locate hospitable planets and sell them to other races looking for living space. But, to make those worlds suitable to their future residents, first we must EXTERMINATE the native inhabitants! When a saiyan warrior is fully grown, he is assigned to the most difficult worlds, with the most powerful natives. But first we warriors must have years of practice, for even as little children, we are, in time, sent to depopulate the WEAKER worlds...Worlds like THIS one! It's a lucky thing this world has a moon...you'd have wiped out all these vermin within the space of a few years...IF YOU HADN'T HIT YOUR DAMNED SOFT LITTLE HEAD!
KRILLIN: If...If this is TRUE...Th-Then all these things, they...they make PICCOLO look like Th' boy next door--!!
GOKU: WAIT a minute...Why is it "lucky" that Earth has a moon...!?
RADITZ: Is your brain THAT badly damaged!? Only when a moon shows her full face do we Saiyans show our true powers!!
KRILLIN, MASTER ROSHI, BULMA: A-HA--!!
GOKU: I've no idea what you're talking about!
RADITZ: That's Because--!! Your TAIL...!! Tell me, what happened to your TAIL--!!?
GOKU: Got cut off a long time ago. Why?
RADITZ: No WONDER you've become so comfortable in the weaklings world! You're passing for one of THEM...YOU, my own brother!!
GOKU: SHUT UP!! I don't care if you ARE my brother! I don't care if I AM an alien!! Krillin was RIGHT-- People like you are just WRONG!! I'm SON GOKU now--!! Get Th' heck off my planet!!
BULMA: You tell 'Im, Goku!
MASTER ROSHI: Nurture over nature, M'Boy! Goku's not just an EARTHLING...He's Th' best dang earthling I know!
KRILLIN: He even SAVED this planet once! So do us a favor an' just GO, will ya!?
RADITZ: Heh Heh Heh...Seriously, though, how do you expect me to do that...? I suppose you've forgotten that Vegeta, The Saiyan homeworld, was destroyed by collision with an asteroid...our entire race reduced to space dust...even our parents. YOUR parents, Kakarrot.
KRILLIN: ...
RADITZ: Of all our proud and mighty race, only four remain...including you! We survived only because we were on other worlds...exterminating their natives. Because we were doing "WRONG" as you put it, we are ALIVE--! WE remaining three recently found a planet which we know can be sold at a VERY high price the locals, howerever are POTENT. Even THREE Saiyan might have some trouble. Ah, but FOUR of us...! Thank the gods I remembered YOU, eh? Even my long-lost, Ill-Trained, amnesiac little BROTHER should be enough to tip the scales. PICTURE it, Kakarrot!!! Picture the CARNAGE! Fell your Saiyan blood STIR!!
GOKU: I WON'T...I'd rather DIE!!
RADITZ: Hmp...how very sad. But do tell me some-thing...is that your WHELP I see behind you?
GOKU: N-NO!!!
RADITZ: Oh, is that so...? I suppose ALL miserable earthlings have tails, then...?
GOKU: You leave him ALONE!!!
RADITZ: Sorry can't be done. If my own brother wont deign to help me...then I'll just have to borrow my tender young nephew, instead...
GOKU: One more STEP--and I'll KILL you--!!!
RADITZ USES ZANZOKEN AND KICKS GOKU IN THE STOMIC
GOKU: ...NGH...!! NNG...GGUHH...!!
GOHAN: DADDY-Y-Y!!
RADITZ: Oh, no, you don't.
KRILLIN, MASTER ROSHI: ...
GOHAN: BWAAAH!!
RADITZ: If you wish him returned to you ALIVE, Kakarrot...You will follow my orders...is that clear?
MASTER ROSHI: RRR...GUHH...!
KRILLIN: He...He beat Goku...W-with ONE KICK, yet...
RADITZ: I'll give you a full Earth day to...shall we say...agonize over it? WHEN you decide to join us...and you WILL decide it...WE shall require...proof...of yoru good intentions. Let's make it simple, One Hundred humans by this time tomorrow. Pile the bodies here, and don't think we won't count. Did you hear me!? I'll be looking forward to tomorrow. This is, after all, my only nephew...I'd hate to have to kill him.
KRILLIN: Y-You WOULDN'T...Y-You CAN'T--!!
RADITZ: Just to make sure we're clear on this...One hundred daed humans. This time tomorrow. Be here or he's dead.
GOHAN: WAAAH!!
RADITZ: Do it, and we fly off together to pile up a few million more bodies. Fail, and there'll be only one dead body--your son's.
GOKU: UNGH...!
KRILLIN: Y-you call yourself a warrior!? Usin' a KID..!?
MASTER ROSHI: H-He's right! If you think Goku'd ever go 'N' kill somebody, You're crazy!!!
RADITZ: The choice is his. If he values a hundred humans over his son. Fine. Although, I feel I should warn you, after my comrades and I exterminate the vermin on that other world...We most certainly shall return, and repeat the process here!
KRILLIN, MASTER ROSHI, BULMA: WHAT!?
KRILLIN: Y-You'll WH-WHA--?!?
RADITZ: I give the inhabitants of your puny planet...oh, lets say a MONTH...Once we three begin the clean-up process...Really, if you think about it, what difference does it make if Kakarrot should happen to give one hundred of you a head start...? Do you SEE now!? Your "choice" is NO choice at all, my dear younger brother!!
GOKU: Give me...back...my...SON...!!!
PICCOLO IS LISTENING IN
RADITZ: Make the RIGHT decision, O my brother...for YOUR sake, as well as his!
PICCOLO: ...!
RADITZ: *in the air* And also, PLEASE...Don't make the mistake of trying to fight me. Even if you HAD the power to challenge me, ,you haven't a fraction of the necessary traininig.
GOHAN: DAA-A-A-D-D-Y-Y-Y--!!!
GOKU: G-GO-O-O-HA-A-A-N!!!
RADITZ: Until tomorrow "Kakarrot"...!! *FLYS AWAY* WA HA HA HA HA !!!
ah thats it...man I"m tired...phew! Hope it helps
