The Limits of Power

Omega Shenron is desperate to reclaim the Four-Star Dragon Ball and complete his set. Goku takes the most direct approach possible: he shoves the ball into his mouth and swallows it, nearly suffocating before it goes down. Omega declares he will simply kill Goku to retrieve it, but Vegeta steps in and refuses to let that happen.

Both Saiyans attack Omega, but neither can land a meaningful blow. Goku manages to headbutt the dragon from behind, causing some pain, and then lectures Omega about fear and the importance of choosing good over evil. Vegeta remarks that he learned the same lesson the hard way, but Omega dismisses them both.

With Omega Shenron tossing them around effortlessly, Goku and Vegeta decide fusion is their only remaining option. But Omega has learned what the dance means and actively disrupts each attempt. The Saiyans create duplicates of themselves to confuse the dragon, and the diversion works long enough for them to perform the full dance.

Nothing happens. They do not fuse. Vegeta demands an explanation, and Goku blames his index finger positioning, though that is not the real issue. Trunks suspects the true cause: Goku has been fighting for so long that his energy reserves are completely depleted. Omega, realizing this, mockingly offers them another try.

Goku attempts the dance one more time, but mid-sequence, his body gives out entirely. He reverts from Super Saiyan 4 to his child form, the transformation collapsing as his power hits zero. The Z Fighters watch in horror as their strongest warrior shrinks before their eyes. Omega Shenron prepares to move in for the kill.

Then something unexpected happens. The Four-Star Dragon Ball emerges on Goku's forehead, glowing with energy. The ball that Goku swallowed has fused with his body in a way no one anticipated. What this means for the battle, and for Goku himself, remains unknown. But the fight is far from over.
