If I had it my way the movies go like this :
DB 1: a 15 year old Goku (12 years old would be too young methinks) who lived in the woods all his life and taught matial arts by his late adoptive grandfather Gohan, who left him his sacred possession to him, his 4 star dragonball. An 18 year old Bulma is searching for the 7 dragonballs to wish for the perfect man. Her search leads to Goku, whom she convinces to come along with her. Meanwhile the incompitant emperor Pilaf also has plans for these balls, to rule the world. Goku and Bulma's search leads them to Gohan's former master, Kammesin Roshi. Roshi has another dragonball. He tells them the tale of when he was a young man, he defeated an evil demon. This demon's name was Piccolo, the evil half of Kami, the guardian of the earth. He used a powerfull technique called the Kamehameha Wave to imprison Piccolo in a sacred jar. As a reward, Kami gave roshi 3 Dragonballs, which Roshi gave one to Gohan and the other to his other student The Ox King. Roshi tells them about a martial art's tournament, which the Ox King is holding. The prize is his Dragonball. Roshi see's potential in Goku, so he decide's to train him along with his other student Krillin. After months of rigorous training they are ready to enter the tounament. Goku manages to make it past opponents Yamch and Tien. Krillen defeats Chou-Tsu, but is eliminated by Tien. In the last round Goku faces the Ox-King's daughter Chi-chi. She puts up quite a fight, but the fight is interrupted by Emperor Pilaf who has an announcement to make. He know's that all of the 7 dragonballs are there and that he wants them to hand them over, or he will release the demon piccolo. No one believes him, but he proves them wrong by releasing the demon king. He commands Piccolo to get him the 7 balls but Piccolo takes orders from no one. He kills Pilaf, Krillin, Chou-Tsu and takes the Seven Dragonballs and summons the dragon Shen Ron and wishes to restore his youth and strength. He then kills shen-ron and heads to Kami's look out tower were he imprison's Kami and his servant Mr. Popo in the jar. The Ox-King gives Goku the sacred flying Nimbus. Goku, Tien and Yamcha head to Kami's tower and confront the demon king. They put up a good fight but are beaten to near death. The fight ends up back on earth where it is now nightime and a full moon at that. Goku, catching his first ever glimpse of a full moon transforms into a giant monkey creature and nearly destroys Piccolo. However, piccolo cuts off goku's tail which reduces him back to his normal self. Chi Chi interfere's but Piccolo kills her too. Goku in full rage unleasehes the mighty Kamehameha wave which puts a whole through Piccolo's chest, killing him. However, before his death, Piccolo spits out an egg, which hatches and a new piccolo is born. Goku, who is too weak to fight, let's him walk away, then passes out. When Goku comes to, he finds himself on Kami's tower, where Kami has been freed by Yamcha and Tien. Kami tells him he can create a new dragon and they use the DB's to ressurect the victims of piccolo. Everyone lives happily ever after (for now). Bulma leaves with her new boyfriend Yamcha and Goku leaves with his new girlfriend Chi-Chi.
Stay tuned for my post for DB2.
