And before you start, I know this completely disregards any reality that DBZ may have been created in. I know the manga existed before the anime but it suits my purposes to have Toriyama-san and a Director discussing the story before it's actually created.
Time Frame: Between DB and DBZ so Chichi is pregnant with Gohan.
Attendant #2: "Number Fourteen. Call for the Fourteenth Audition - Name Crane Master."
[The ever familiar Crane Master walks in with his silly hat.]
Most of the cast: "..."
Tenshinhan: "What do you want?"
Toriyama: "You're not supposed to ever reappear! NE..."
Crane Master: "Now, now! You really ought to give every one fair time." (snidely) "Unless, that is, you want me to give you a bad reputation and tell everyone how I was kicked out before I got my chance to audition. Well?"
Director: "Alright, but you had better make it good."
Crane Master: "Eh?"
Cast (collapsing): "..."
Toriyama: "What exactly did you come here for?"
Piccolo: "You're old!"
Crane Master: "You're a fine one to talk! You're over 600 yourself!"
Piccolo: "But I kept my youth!"
Yamcha: "You're powerless!"
Crane Master: "And you're one of the weakest fighters there are!"
Yamcha: "I know. I'm just cannon fodder."
Goku: "You're one of Master Roshi's enemies."
Crane Master: "Past involvement in the series is a point in my favor, Son Goku."
[The rest of the cast nod their reluctant agreement.]
Goku: "..."
Tenshinhan and Choazu: "You're studentless."
Crane Master: "Only because you two deserted me."
Toriyama: "In short, you're too old, too powerless, were involved with the wrong character and have no students. You've got nothing to offer the series! NEXT!"
[As the Crane Master reluctantly leaves he can be heard muttering.]
Crane Master: "I'll get my revenge. A demon of a Tenkaichi Budokai Champion will rain havoc on your series. Satan will be my revenge!"
Attendant #2: "Number Fifteen! Call for the Fifteenth Audition - Name Alien."
[A spindly black drooling alien flowed in. I use the word flow, since walk fails to capture the deadly grace of the creature. A tallish woman with short hair accompanies it.]
Toriyama: "This looks interesting."
Freeza: "This could be bad."
Woman: "I'm just a spokes person for it. So please focus your attention on the alien."
Director: "Spokes person?"
[On cue the alien opens it's mantiples and extends its 'tongue.' Drool goes everywhere.]
Bulma: "Eew! Gross."
[Puar immediately hides behind Yamcha and Oolong ducks behind the nearest person as well.]
Puar and Oolong: "It's going to eat us!"
Woman: "With a jaw like that, do you think it can talk?"
Toriyama: "It does look impressive though."
Director: "Why don't you tell us something about it?"
Woman: "It is actually a them. There is almost always more than one of them. Even if you start off with one, you'll soon have others."
Toriyama (nodding): "Quickly multiples. A useful trait."
Woman: "This is a warrior type. They are ruled, insect like, by a queen, whose sole purpose is to produce eggs. In fact, their whole goal is to replicate their species, but to do that they need hosts."
Director: "So their goal on Earth would be?"
Woman: "To make everyone a host. They originally come from space and have been traveling from planet to planet."
Toriyama: "What about their fighting ability?"
Woman: "This is a fighting series isn't it? Well, as you can see, it's got some very sharp teeth and claws. You can not cut them since their blood is highly acidic and will melt anything it touches. It will melt the earth through to lava if enough is applied."
Goku: "Wow!" (he at least knows a formidable opponent when he sees one)
Woman: "Their most useful ability is that it's blind. It doesn't need eyes to see you and it has a 720 degree awareness or its surroundings. You simply cannot sneak up behind it."
[The fighters who are still paying attention look a little worried. They might be the heroes of the series but even they will strike from behind if they must.]
Freeza: "It's very impressive but there is a fatal flaw!"
Toriyama: "Freeza, you've already been accepted so what's the problem?!"
Freeza: "They're not an ANIME/MANGA character!"
Toriyama: "NANI?" (to woman) "Is this true?"
Woman (shrugs): "Yeah. So what?"
Toriyama (spluttering): "S...So what? It's everything! DBZ is manga/anime series! How can I put a real action character in there?"
Freeza: "And they look like my third transformation!"
Woman: "Correction - you look like they do!"
Freeza: "Does it matter?" (to Toriyama) "Toriyama-san, their particular form is already in your series, thanks to me, the great Freeza-sama! My third form looks fairly similar to them."
Toriyama (still spluttering from the concept of a non manga/anime character): "It does?"
[Freeza and his henchmen nod.]
Freeza and henchmen: "It does."
Toriyama (happily): "Then that solves the problem! I'll just have to
make sure that you go through all your transformations and that way we'll
be able to include something like them."
Freeza (angrily): "Me? Go through all my transformations! I hardly think I will need to."
Director (placidatingly): "Your transformations are there are as a reserve feature of you. It is yet to be seen whether you will need them all or not." (to Alien) "I'm sorry, but we cannot offer you the part at this point in time. Thank you for your audition."
Toriyama: "NEXT!"
Attendant #2: "Number Sixteen. Call for the Sixteenth Audition - Name Saiyajin's."
Freeza: "What? Saiyajins? They are my servants!"
[Vejiita, Radittsu and Nappa walked in, in that order. They all had scouters and the haunty expression that adorned their race. And from the perspectives of the cast they were dressed in the same armor as Freeza's group, although theirs was universally accessorised by a furry belt.]
Vejiita: "We'll audition for what we want Freeza-sama. After all, you told us to go away for a month."
Freeza: "Feh! You've got no hope!"
Toriyama: "Freeza! You have already been accepted and while your help with the previous audition is appreciated, could you please give the other auditions the politeness they deserve."
Bulma (over Vejiita and Radittsu): "Kakkoii..."
Yamcha (without much expression): "..."
[Freeza backed off a little. It's amazing the power that the series author had.]
Director: "Why don't you tell us about yourselves?"
Vejiita: "I am Vejiita, the Saiyajin no Ouji. We are the premier warrior race in the galaxy."
Freeza and Henchmen: "Bwahahahahahahah!"
Attendant #1 (in a harsh whisper): "Could you please remain silent?"
Radittsu: "Our home planet was destroyed by an asteroid..."
Dodoria (in a sing song voice): "That's what you think."
Radittsu (continuing): "So we will fight anyone, at anytime. Even if we are out numbered we do not back down."
Toriyama: "Adds a good tragic aspect. Are you the last of your kind?"
Nappa: "Yes."
Toriyama (nodding): "Very tragic." (he ticked off some items on his checklist)
Director: "Attendant! Check their power levels!"
Attendant #3: "Yes sir!"
[The attendant passed the scouter over the group.]
Attendant #3: "They are just within the limitations that you've set sir."
Vejiita (angry): "We'll be more than just! Every fight that a Saiyajin survives makes them stronger, and the closer they get to death but still survive, the stronger they can get."
Toriyama: "A very useful trait!" (to self) "And it would explain some of Goku's strength!" (to attendant) "What's their exact levels?"
Attendant #3: "Vejiita is the most powerful at 18 000, Nappa is the next at 8000 and Radittsu is the weakest at 1200."
Toriyama (disappointed): "That low?"
[Buu and the Ginyu force pulled mock astonished faces at the Saiyajins. They knew they were weak!]
Vejiita (frustrated): "You..."
[Vejiita's tail unwound from his waist because of his frustration.]
Toriyama and Goku: "Ara? You've got a tail!"
Vejiita: "Of course I've got a tail!"
Goku: "Just like I used to have!"
Toriyama (to self): "Just like Goku used to have..? I can use that! I could make it explain so much if he was an alien!" (To Vejiita) "Do you transform?"
Nappa: "All Saiyajin transform with the sight of a full moon! All saiyajin with a tail."
Toriyama (excitedly): "Wonderful!"
[The assembled cast look a bit surprised at the strength of response Toriyama is showing.]
Toriyama: "I've got two more questions for you."
Radittsu: "What are they?"
Toriyama: "What does your transformation look like?"
Vejiita: "It's an Oozaru transformation. It looks like a giant monkey."
Toriyama (happy stars in his eyes): "And what's your relationship with Freeza?"
Nappa: "We work for him. Ever since Vejiita-sei and even before, Saiyajin have worked for Freeza."
Toriyama: "Wonderful. You're in! I'll forward details of your coming battles to you soon." (to self) "They're perfect! Tails, transformations, everything, just like Goku. I can explain so much! And..." (an evil grin appears) "'You stuck on fat and pink?' They're not fat and pink." (looks at Bulma) "Oh, I can really work with this!"
Director: "NEXT!"
Attendant #2: "Uh, sir? They're the last ones."
Director: "Finally! Alright everyone, you're all dismissed for the moment. Would the new cast members please stay so that they can formalise their contracts."
[Toriyama gets up, still with the evil grin and plans forming in his head. The other established cast members leave quietly, unaware that Toriyama is going to change their lives forever or perhaps they might have stayed to argue with him as he went about he business of drawing his manga.]
Goku (on Kintoun): "Well bye bye minna. I'll see you when we get together to make the script! Come on Chichi, let's go!"
[Goku and Chichi fly off.]
Bulma: "Come on Yamcha! You promised you'd go shopping with me after the auditions." (looking at Yamcha with a wicked gleam in her eyes) "But after that..."
Yamcha: "Oh? After that..?"
[The two of them disappeared. Kuririn, Muten Roshi and Turtle pilled into a capsule plane and left for the Kame House. Tenshinhan and Choazu flew off with Ranchi following on a flyer. Piccolo snorted once at the assembled Bad Guys and then himself flew off to continue training. He had to perfect that move before the next battle, the move he was developing to defeat Son Goku once and for all. Kami-sama and Mr Popo disappeared in a flash of light back to the sanctuary.]
Puar: "I guess that means we've been left alone."
Oolong: "Again..."
Puar: "At least with the new people's power levels we won't be fighting."
Oolong: "That's something at least!"
Puar: "Another day another dollar, right?"
Oolong: "Yeah, right."
Puar and Oolong: "WHY ARE WE ALWAYS LEFT BEHIND?"
The alien comes from Alien.
Well, that's the final casting call. I hope people have enjoyed them
