Goku vs. Tambourine — Rematch
SPOILER!
Episode 107 · Anger with a full stomach this time
Goku's first attempt at Tambourine ends with an exhausted, furious kid getting beaten. The rematch happens after he has recovered and can actually fight the opponent in front of him.
The Breakdown
Dragon Ball uses the pair of encounters to separate anger from effectiveness. Goku is just as furious the second time, but now the body underneath the anger can keep up. Tambourine goes from untouchable murderer to somebody Goku can finish decisively.
Goku vs. King Piccolo — First Fight
SPOILER!
Episode 109
After killing Tambourine, Goku finally gets the enemy he actually wants. King Piccolo stops him cold. The gap is so severe that Goku is left with no meaningful answer and is abandoned as a corpse.
The Breakdown
This is the Tao lesson at a much darker scale. Rage has carried Goku to the correct target, not to the strength required to beat him. The story has to find another way to move Goku's ceiling before a rematch can even be plausible.
Goku vs. King Piccolo — Final Battle
SPOILER!
King Castle · Episodes 119–122
Goku returns after surviving the Ultra Divine Water and can finally trade blows with Piccolo's restored youth. Piccolo answers by attacking everything around the fight: hostages, the city, Goku's limbs, anything that can turn a straight contest ugly.
The Breakdown
By the finish Goku has almost nothing left functioning. He fires a
Kamehameha downward with his remaining arm to launch himself upward and drives through Piccolo's body. It is not elegant. It is the original series turning every remaining piece of Goku into forward momentum.
