The Dragon Ball universe is known for epic battles, shocking transformations, and rivalries that push characters beyond their limits. But in this fan manga continuation, the story takes a chilling new path. This time, Goku is no longer the cheerful warrior who fights for Earth. Instead, betrayal and tragedy turn him into something darker — the God Killer.
This is not the Goku fans grew up with. This is a Goku born from pain, fueled by vengeance, and willing to destroy everything in his way.
The Fall of a Hero
It all begins with betrayal. After Beerus and Whis unleash devastation, Goku loses everything he has ever loved. His family, his friends, and even Earth itself are gone in an instant. For the first time in his life, Goku stands truly alone.
Consumed by grief and anger, he seeks guidance from King Kai. But instead of peace, he finds only more fuel for his rage. To his shock, Vegeta has survived. Yet what could have been a moment of unity quickly becomes another conflict.
Goku wants revenge immediately, no matter the cost. Vegeta, however, argues that survival and patience are the key. Their differences, once a healthy rivalry, now plant the seeds of betrayal and destruction.
The Pyramid of Power
King Kai warns that Goku is not ready to face Beerus. That is when the Grand Kai enters, revealing secrets that could change their destiny. He introduces the Pyramid of Power, a realm where ten years pass inside while only a single day moves in the outside world. Along with it, he reveals the Black Potara Earrings, powerful artifacts capable of creating an eternal fusion without time limits.
With no other path forward, Goku and Vegeta accept the challenge. They step into the Pyramid, beginning a training arc that lasts a decade and pushes their rivalry to frightening new heights.
Rivalry Beyond Limits
Inside the Pyramid, the two Saiyans clash over and over again. Their duels shake the very foundation of the realm as they revisit old forms and unlock new powers.
They fight at the level of Super Saiyan 2, test their limits with Super Saiyan 3, and train under crushing weights and impossible conditions. Vegeta, through sheer determination, awakens Super Saiyan God without the need for a ritual. Both eventually master Ultra Ego, their powers climbing into divine territory.
But with every step forward, their hearts grow further apart. Goku cannot let go of his obsession with revenge. He lives only for the day he can strike down Beerus. Vegeta, on the other hand, dreams of using the Dragon Balls scattered across the universe to revive their families and restore their world.
This difference in purpose creates a storm that neither of them can escape.
The Betrayal of Vegeta
When their training reaches its peak, the Grand Kai gives them the Angel-Grade Potara Earrings. Together they fuse, creating the unstoppable warrior Ultra Ego Vegito. On the outside, they appear united. But inside their shared mind, the conflict rages on.
Vegeta demands that they seek the Dragon Balls. Goku insists that vengeance must come first. The argument escalates into an inner war, and in one of the darkest twists of the Dragon Ball story, Goku makes his choice.
He turns on Vegeta, tearing out his heart within the shared consciousness. With Vegeta silenced forever, the fusion breaks. Yet Goku does not return to his old self. Instead, he emerges alone, carrying Vegito’s godlike power in his own body.
This is the moment the legend of the God Killer Goku is born.
Goku’s March Toward Beerus
When Goku leaves the Pyramid, he deceives the Grand Kai, claiming that Vegeta still exists within him. With the Angel Staff in his possession, he prepares for the confrontation he has been waiting a decade to face.
He arrives during a sparring match between Beerus and Whis. Without hesitation, he steps forward, his aura darker than ever before. When Beerus throws a punch, Goku catches it with one hand. His eyes, cold and merciless, lock onto the God of Destruction.
“I’ve waited ten years for this moment,” Goku declares. “Today… I become the God Killer.”
Conclusion: A Hero Consumed by Darkness
The God Killer Goku origin story is one of betrayal, tragedy, and revenge. It transforms Goku from the cheerful savior of Earth into a warrior broken by loss and driven by obsession.
But the question lingers: will his vengeance against Beerus finally bring him peace, or has his descent into darkness already doomed him beyond redemption?
For Dragon Ball fans, this story is not just about power — it is about the cost of obsession, the fragility of trust, and the chilling reality of what happens when a hero becomes something far more dangerous than a villain.
