DBZ Episode 18

Story

Son Gohan and Piccolo continued to fight each other. Gohan was obviously outmatched, but did not give up. Son Goku continued to run on the Serpentine Road. That night, Gohan has a dream about when Raditz attacked his father and becomes totally enraged. He hears a voice saying, "Wake up, Kakarot", and responds to it as if he were Goku! Piccolo hears his screaming and flies to him. Gohan attacks Piccolo and seems to be doing much better than he did before by actually giving Piccolo a good fight. Piccolo continues to fight Gohan, and splits into two beings in order to better his chances. While one Piccolo fights, the other watched on. Piccolo sees that Gohan's tail had grown back, and deducts that it only takes six months to grow back. Piccolo turns around and sees the moon, which has mysteriously came back. Piccolo looks around, and sees that it is coming from Goku's original space capsule.

Meanwhile, Turtle Hermit, Bulma Brief, and Oolong had a congratulations party after they had found all of the Dragon Balls. They looked up at the sky and saw that the Moon was back. Gohan got a sucker punch in on Piccolo causing the two beings to fuse together again. Piccolo trapped Gohan in a electricity web, but it caused Gohan to look directly at the Moon and he transformed into a Great Ape. Piccolo evaded Ggreat Ape Gohan's maneuvers and eventually had to destroy the ancient space capsule itself. Great Ape Gohan transformed back and Piccolo removed his tail again.

Meanwhile, Goku reached the tail end of the Serpentine Road. When he got there, he found that there was actually nothing there. He looked up, however, and saw a small planet high above. He flew up to it and saw a house and a car. Just then, the gravity weighed him down and he crashed straight into the planet. He saw a fruit-bearing tree and tried to climb it, but he fell off. He then saw a Monkey behind him and assumed that he was North Kaio. He asked "North Kaio" to get him one of the fruit from the tree, but it fell so fast that it went right through the ground. The monkey came down and started to parade around, so Goku mocked him. Suddenly, the real North Kaio appeared and introduced himself with one of his signature corny jokes.

Major events

• Goku reaches the end of the Serpentine Road.
• First appearance of North Kaio and Bubbles.

Trivia

• Gohan's Great Ape transformation is filler.
• The filler portion of this episode establishes a six-month time frame for Gohan's tail to grow back, foreshadowing its return in "The Battle Ends".
• Destroying Goku's space pod is contradictory to later canon events where Dr. Brief uses it to build Goku a space pod. It could be argued that Dr. Brief actually got Raditz's space pod (broken to pieces, but not completely destroyed), however, after discovering that Goku's was destroyed.
• Despite being aware that a tail is necessary for the transformation, Piccolo never considers removing Great Ape Gohan's tail as a way to stop him. In addition, he always removes the tail after destroying the moon (or anything that resembles moonlight), without which such a transformation should not be feared (in the uncut version, Piccolo explains why he is taking both precautions because the lack of a moon would prevent the evil Saiyans from transforming and Gohan's tail, even without the moon, was only a liability due to Saiyans having a weakness there).
• Goku makes a statement about Sir Issac Newton after Bubbles drops an apple from an apple tree.
