When I think about the heart and soul of the Dragon Ball universe, my mind always goes straight to Goku. For decades, we’ve known him as the ultimate symbol of good, a pure-hearted Saiyan who always fights to protect the innocent. He’s the cheerful, powerful hero we can always count on to save the day, no matter how impossible the odds seem. His unwavering optimism and desire to do the right thing are as much a part of him as his spiky hair.
This raises a chilling question: what if our greatest hero became the villain? Just imagine the one person everyone trusts to save them suddenly becoming the very thing they need saving from. This isn’t just a fan theory; the Dragon Ball series has actually explored this dark possibility through alternate timelines and what-if scenarios. The result is a world where its strongest protector becomes its most unstoppable threat, turning hope into absolute terror.
We’ve seen glimpses of this horrifying concept in a few different ways, proving just how devastating it would be. The most famous example is the terrifying Goku Black from Dragon Ball Super: a villain who stole Goku’s body to carry out a deadly plan to erase all mortals. Even earlier in the original series, we saw a young Goku lose all control and become a destructive monster in his Great Ape form, a transformation that tragically led to the death of his own Grandpa Gohan.
Key Takeaways

Goku Black and the Zero Mortals Plan
The most famous example of an evil Goku we’ve ever seen is, ironically, not even Goku at all. In Dragon Ball Super, we were introduced to Goku Black, a villain who looked exactly like our hero but with a much darker, more sinister energy. I remember how confusing it was at first, but we soon learned the truth: he was actually a Supreme Kai apprentice named Zamasu from an alternate timeline. Zamasu, who despised mortals, used the Super Dragon Balls to wish for Goku’s body, stealing his power to carry out his twisted “Zero Mortals Plan.” His goal was to erase every single mortal from existence, believing them to be a failed creation.
What made Goku Black so terrifying wasn’t just his stolen face, but the unique powers he developed with it. He unlocked his own divine version of a Super Saiyan transformation, the stunning but deadly Super Saiyan Rosé. On top of that, he could create ki weapons out of thin air, like his infamous Sickle of Sorrow. This combination of Goku’s incredible fighting potential and Zamasu’s divine knowledge made him one of the most formidable foes ever. He and his alternate timeline self pushed Goku and Vegeta so far that they had to fuse into Vegito Blue just to keep up in the climactic battle (Dragon Ball Super episode 66, The Climactic Battle! The Miraculous Power of a Relentless Warrior!).
Beyond his immense power, Goku Black represented a horrifying psychological threat to our heroes. Imagine seeing the face of your greatest friend and protector twisted into a symbol of pure destruction. This was the reality for Future Trunks, who watched this evil Goku systematically wipe out what was left of his world. Zamasu’s cold, righteous personality inside Goku’s body created a chillingly effective villain who was completely devoid of the warmth and kindness we associate with Goku. He was the ultimate “what if” scenario, showing just how dangerous Goku’s body could be in the hands of someone truly evil.
Great Ape Goku’s Uncontrollable Rampage
To find Goku’s first turn to the dark side, we have to go all the way back to the original Dragon Ball series. This wasn’t a conscious choice to be evil, but an uncontrollable transformation he underwent. Whenever Goku looked at a full moon, his Saiyan blood caused him to turn into a giant, rampaging Great Ape. In this state, he was a mindless beast, destroying everything in his path with no memory of his actions afterward. This raw, untamed power was our first glimpse of the terrifying potential lurking inside our cheerful hero.
The consequences of these transformations were devastating and deeply personal. We later learn that one of these rampages was responsible for the death of his beloved Grandpa Gohan, a fact Goku himself didn’t know for a long time. Another great example of his destructive power was when he transformed and completely flattened Emperor Pilaf’s entire castle. This early display of power showed that even as a child, Goku was a force of nature that could cause immense destruction, which we see happen right after the gang’s first wish on the Dragon Balls (Dragon Ball episode 12, A Wish to the Eternal Dragon).
The Saiyan Mission: What If Goku Never Hit His Head
It’s the ultimate “what if” for any Dragon Ball fan: what if Goku never hit his head as a baby? I think about this all the time, and the answer is pretty dark. He would have grown up as Kakarot, the ruthless Saiyan warrior sent to wipe out all life on Earth. He would have retained his aggressive Saiyan instincts and followed his mission without question, just as Raditz expected when he first arrived. This single event completely changed the course of history, turning a potential planet-destroyer into its greatest hero, a detail we first learn in the opening episodes of the series (Dragon Ball Z episode 1, The New Threat).
An evil Kakarot probably would have conquered Earth with ease, especially by using his Great Ape transformation. I imagine he would have waited for a full moon and simply stomped civilization into dust, just like Vegeta and Nappa planned to do. This is a far more terrifying version than the mindless rampage we saw when he accidentally killed Grandpa Gohan as a child. In this scenario, there would be no Master Roshi, no Krillin, and no Z-Fighters to ever stand against future threats like Frieza or Cell.
While the story of Kakarot remains a “what if,” the series did give us a taste of an evil Goku with Goku Black. He serves as a perfect example of what happens when Goku’s body is controlled by a malevolent mind. Instead of a primal Saiyan, Goku Black was a fallen god with a specific, genocidal goal. He twisted Goku’s abilities to create his own Super Saiyan Rosé form, proving so powerful that it took a fused warrior just to fight him. This shows that no matter the origin, an evil version of Goku is a catastrophic threat.
Mindless Beast vs. Cruel God
We’ve seen just how terrifying an evil Goku can be, from the mindless destruction of his Great Ape form to the calculated cruelty of Goku Black. While Great Ape Goku was a temporary, animalistic threat, Goku Black was something far more sinister. He combined Goku’s incredible power and potential with the cold, genocidal ambition of a fallen god. Seeing our hero’s face twisted into a smug, evil grin while he wielded powers like Super Saiyan Rosé was truly chilling. These versions show us that a corrupted Goku isn’t just a physical threat, but a psychological nightmare.
The idea of an evil Goku is so fascinating because he would be the perfect, unbeatable villain. We’ve always counted on him to push past his limits and save the day, so what happens when that same drive is used for evil? His relentless desire to become stronger would no longer be for protecting the innocent but for dominating them completely. There would be no hero powerful enough to stop him, creating a true doomsday scenario for the entire Dragon Ball multiverse. An evil Goku represents the ultimate betrayal of hope.
Exploring these dark possibilities really makes you appreciate the pure-hearted hero we know and love. Goku’s greatest strength isn’t his Saiyan biology or his transformations, but his unwavering goodness. While it’s fun to imagine these dark “what-if” timelines, they all prove one thing: the universe is incredibly lucky to have Goku on its side. His simple, kind nature is the bedrock of the entire series, and without it, there would be nothing but despair.
