Old Kai reveals he can unlock a person's dormant potential beyond all limits, though the ritual takes over twenty hours. On Earth, Goten and Trunks finally perform a successful Fusion and become Gotenks, who immediately rushes off to fight Buu.
After some dubious persuasion from Goku, which reportedly involves promises that would make even King Kai blush, the eccentric Old Kai agrees to help unlock Gohan's hidden potential. He reveals that he possesses the ability to draw out a warrior's latent power far beyond their natural limits, a process that requires no weapon, no transformation, and no external power source. The catch is significant: the ritual is extremely lengthy, requiring Gohan to sit perfectly still for over twenty consecutive hours while the Old Kai performs an elaborate, seemingly nonsensical ceremony around him. The process tests patience and willpower more than physical strength, but the promised result is a power that surpasses anything achievable through conventional training or even Super Saiyan transformations.
Meanwhile at the Lookout, Goten and Trunks attempt the Fusion Dance for the first time under real conditions. Piccolo oversees the process with intense focus, watching every angle and finger position. Their initial effort goes terribly wrong when one of the boys makes an error in the symmetrical poses, resulting in a grotesque, overweight version of the fused warrior that can barely waddle, let alone fight. A second attempt produces an equally useless, rail-thin fusion with virtually no power. Piccolo's patience, already strained to its breaking point, wears thinner with each embarrassing failure. The fate of the world hinges on two children who cannot seem to point their fingers in the right direction.
On their third and most carefully coordinated attempt, Goten and Trunks execute the Fusion Dance with perfect synchronization. Every arm angle matches precisely, every step lands simultaneously, and their fingertips touch at the exact correct moment. The two boys merge in a blinding flash of light into a single extraordinary warrior: Gotenks. This is the true fused form, brimming with raw confidence and a power level that dramatically exceeds what either boy could produce individually. Gotenks surveys his new body with obvious satisfaction, flexes experimentally, and immediately declares himself more than strong enough to obliterate Majin Buu without any further preparation or strategy whatsoever. His cockiness is total, absolute, and entirely unfounded in reality.

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....

Dragon Ball handed us a protagonist with no history and the internet named him John Dragon Ball. So we built him somebody to talk to....
Completely ignoring Piccolo's urgent and increasingly desperate warnings about the dangers of rushing in unprepared, Gotenks rockets away from the Lookout at tremendous speed to confront Majin Buu directly. The fused warrior's staggering arrogance blinds him entirely to the reality of his situation. He has not tested his power against a genuine threat, has formulated no strategy beyond charging in headfirst, and does not even fully understand the limits and capabilities of his own fused body yet. Piccolo can only watch helplessly from the Lookout's edge as the planet's best and only real hope for survival flies headlong into a battle he is not remotely prepared to win.
