Dragon Ball · Major Antagonist / Demon King

The ancient, terrifying Demon King freed by Emperor Pilaf who shifts Dragon Ball into high-stakes dark fantasy. The literal evil purged from Kami's soul, King Piccolo assassinates world martial artists, murders Krillin and Roshi, restores his youth with Shenron, and executes the dragon immediately after. He represents pure, unadulterated malice until Goku punches a hole clean through his chest.

King Piccolo Makes the Dragon Balls Feel Mortal

SPOILER! Open →

Youth restored · Shenron killed · Kami becomes essential

King Piccolo understands the Dragon Balls better than most villains before him. He does not just make a wish. He restores his youth and immediately kills Shenron so nobody else can use the same system against him.

That single decision changes the problem from 'beat the villain and wish everybody back' to 'beat the villain while the reset button is gone.' The later reveal that Shenron can be restored only because Kami still exists quietly expands the divine side of Dragon Ball's world.
Why it matters
The franchise's signature safety net becomes part of the stakes instead of sitting outside them.

Krillin's Death Changes the Rules

SPOILER! Open →

Episode 102 · Goku stops thinking

Goku finds Krillin dead immediately after the tournament and does exactly what his friends tell him not to do: he chases the killer while exhausted and furious. Tambourine beats him badly.

That failure matters. Goku's instinct has always been to run directly at the problem because being stronger usually makes that reasonable. King Piccolo's story repeatedly punishes that assumption. Roshi dies attempting the Mafuba. Chiaotzu is killed trying to stop Piccolo's wish. Shenron himself is destroyed after granting it.
What changed
For the first time, the Dragon Balls do not make death feel automatically temporary. The mechanism that normally repairs the damage is attacked too.

Goku vs. King Piccolo — First Fight

SPOILER! Open →

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! Open →

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.
