Dead Zone
In the beginning (Dragonball), Kami landed on Earth and created the 7 legendary Dragon Balls. To become pure of heart, the Namek separated into two forms- one good and one evil. The evil replica had a son, who became known as Piccolo! After battling Goku, Piccolo faced defeat. Because Piccolo and Kami are so related, they held a bond of life. When one perished, the other died as well...
Garlic Jr., a rival of Kami, decided to kill Kami through the destruction of Piccolo. As a result, at the beginning of the movie, Garlic Jr. sends his henchmen to kill Piccolo. After a battle, Piccolo escapes with barely his life.
Garlic Jr. decides that he must get stronger so he seeks the Dragon Balls to be granted the wish of immortality. Gohan, meanwhile, wore a hat that had the four star dragon ball on it. So he gets kidnapped for his hat. (He does not know how to fight at this time.) Then, Goku goes to rescue his son with Krillin. At Garlic Jr.'s black island, Goku and Krillin are joined by Piccolo. Goku and Piccolo fight and kill Garlic Jr.'s henchmen. Krillin finds Gohan and carries him and looks for a safe place to hide. Meanwhile, Kami faces Garlic Jr. and gets beat up. Goku and Piccolo finally find Garlic Jr, but Garlic Jr. has already been granted his wish! Garlic Jr. changes into his muscular battle form and fights Goku and Piccolo. Goku and Piccolo are beaten. Garlic Jr. praises how strong he's become and creates a portal that would suck everything into a world of eternal nothingness (Kami did the same to Garlic Jr.'s father). Gohan regains consciousness and sees the threat of Garlic Jr. He gets angry and blasts Garlic Jr. through his own portal. Garlic Jr. is sucked into the dimension of nothingness for eternity and all returns to normal. At the end, Gohan forgets all that has happened and returns home with Goku.
Here, the first alliance between Piccolo and Goku is shown, and Gohan's secret powers are revealed for the first time...

The World's Strongest
Oolong steals Bulma's Dragon Radar to locate the Dragon balls. (Oolong wants to make a wish for a girl's underwear.) He and Gohan are in the northern glaciers to find the Dragon balls, but Dr. Wheelo's assistant, Dr Willow, wishes for Dr. Wheelo to be freed from his icy tomb. Gohan and Oolong go near the lab to investigate, but are attacked by bio-men. Piccolo rescues them, but is defeated by three androids. Meanwhile, Gohan and Oolong escape.
A few days later, Dr. Willow appears with bio-men in the Kame House and kidnap Bulma. She is used to lure Master Roshi to Dr. Wheelo's lab in the glaciers. In the lab, we meet Dr. Wheelo. It turns out that he is a giant brain functioning inside a giant machine. 50 years ago, Dr. Wheelo and his lab were destroyed and buried in ice. Now that they are released with the help of the Dragon balls, Dr. Wheelo wants to find the strongest man on Earth and take over his body. (He believes that Master Roshi is the strongest because Master Roshi won the martial arts tournament at the time he got "iced".) Next, Master Roshi is put in a secluded room to fight the three androids that defeated Piccolo. Master Roshi is defeated with ease.
Meanwhile, Goku is on his way to rescue Bulma and Master Roshi. Dr. Wheelo's computer picks up Goku's signal. Bulma sees it and exclaims that Goku is the strongest man, not Master Roshi. Dr. Wheelo wants to see if this is true and sends his three androids to fight Goku to see if he's really as strong as Bulma says he is. Goku fights them and is soon joined by Gohan and Krillin. They kill the androids and find Dr. Wheelo. Here, they meet with Piccolo, who is brainwashed by some golden straps placed around his head. Goku and Piccolo battle while Gohan tells them to stop fighting and gets kicked by Piccolo a few times. Because Dr. Wheelo brainwashed his idol (Piccolo), Gohan gets very angry (and you know what happens when he gets angry) and releases a shockwave that almost breaks the glass that holds Dr. Wheelo's brain. This shockwave releases Piccolo from Dr. Wheelo's control. Meanwhile, Krillin tries to rescue Bulma but ends up running from Dr. Willow's machine-gun arm. Master Roshi escapes Dr. Wheelo's prison and aids Krillin. Bulma is freed.
With the tie of the battle turning, Dr. Wheelo gets angry. It turns out that the machine Dr. Wheelo is placed in is really a robot built into the lab. Dr. Wheelo unleashes his body (thus destroying the lab) and begins to attack our heroes. The robot seems unable to be defeated, but Goku creates the spirit bomb while Piccolo and Gohan try to hold him off. Goku successfully blasts Dr. Wheelo with the spirit bomb and kills him. It's a VERY feirce battle, watch it if you ever get the chance!
Afterwards, the good guys stand together and joke that Master Roshi is really the world's dirtiest man and Piccolo walks away.

The Tree of Might
The Z crew are camping in a forest. Meanwhile, Turles and his crew are looking for a planet with rich energy sources that can support the life of their special tree. (This tree grows by eating away the energy of the planet it grows on. Whoever eats its fruits can receive a huge amount of energy- Turles and his crew want the power from the fruits.) One of Turles's space probes crashes into the earth and starts a forest fire. This probe tells Turles that Earth is a planet capable of supporting his tree. At the same time, Gohan, Krillin, and Goku battle the forest fire and saved the wildlife living in it. Here, Gohan saves his pet. The Dragon Balls are then used to restore the burned-out forest.
Back in the Kame House, King Kai transmits the news of Turles and his plot to Goku. Goku tells the rest of the Z crew about Turles and they head out to destroy the energy-eating tree that has already been planted. Goku, Gohan, Yamcha, Krillin, Tien, and Chautzu all do fireballs against the tree, but the tree remains unharmed. The Z Warriors then encounter Turles's henchmen and they battle. Piccolo joins the fight. At the end, all the Z Warriors are defeated except Goku and Gohan. Gohan runs into Turles and misunderstands him for his father. (Turles and Goku look exactly alike, but are not related. Turles also has darker skin.) Turles trashes Gohan and realizes that Gohan is a Saiyan. He asks Gohan to join him in the Saiyan Conquest, but when Gohan refuses, Turles creates a false moon. He forces Gohan to look at it and Gohan's tail grows back. As you can guess, Gohan turns into a were-monkey. Goku, trying to get to Gohan, is blocked off by some of Turles's crew. He easily disposes of them! Gohan loses control as a were-monkey and starts trashing everything. Goku tells Gohan to gain control and go after Turles, but he doesn't. Then Gohan sees his little animal friend he met in the woods earlier. He begins to play with it and Turles gets angry, at that, he fires an energy ball at Gohan. Even though Gohan is a were-monkey, he is still no match to Turles and Turles uses Distructo Disc to cut off Gohan's tail. Gohan turns into a small boy again, unconcious.
Now only Goku and Turles remain. When Goku refuses to join Turles, they fight. Turles whoops on Goku, Goku isn't really strong enough to take on Turles. Turles sees the tree now bears fruit and grabs one, he takes a bite. He receives an enormous amount of power and slams his elbow into Goku. Turles then gives Goku a huge amount of rapid blasts to the chest. Turles flies off above. But, Goku keeps telling himself that he must save the Earth so he cannot die. As a result, he creates a small Spirit Bomb with what's left of the Earth's power, which blasts Turles through the tree. Both Turles and his tree are destroyed. Upon the tree's destruction, energy is released are restores it to the damaged Earth.
