Dragon Ball Z: The Concept of Fusion Explained
Dragon Ball Z has established the concept of fusion, with the two most well-known methods being the Fusion Dance and Potara earrings.
Firstly, the Fusion Dance in Dragon Ball is a technique that Goku learned from the Metamorans, an alien race from another dimension. This method allows two individuals to merge into a single, more powerful being, requiring that both participants have equal strength.
Secondly, the use of Potara earrings is a fusion method that is both quick and powerful, with one simple requirement: each participant must wear one earring from the Kaioshin. With Potara earrings, anyone can fuse together without the need for equal strength.

Among the powerful fusion warriors, the Majin Buu Saga introduced a particularly strong fusion warrior, Vegito (the fusion of Goku and Vegeta using Potara earrings). This fusion represents the combination of Gohan and Goku.
In the Majin Buu storyline, Goku returns to the battlefield with the Potara earrings from Kaioshin to assist Gohan in battling Super Buu, after the evil foe absorbed Piccolo and Gotenks. Goku’s intention is to fuse with Gohan, but ultimately, it doesn’t happen. The potential power of the fusion raises the question: how strong could Goku and his son become together?
The Power of the Fusion between Goku and Gohan in Dragon Ball

In the final chapters of Dragon Ball Z, Goku and Gohan are two of the most powerful Saiyans, making their potential fusion the strongest among all. At this point, Gohan has reached the “Mystic” state, unlocking his latent power to match Super Saiyan 3, allowing him to easily surpass Super Buu. This accomplishment places Gohan far beyond Vegeta’s level.
Goku, in Super Saiyan 2 form, was capable of fighting evenly against Vegeta in Super Saiyan 2 as well, but Vegeta had an advantage due to Babidi’s magic, while Goku remained composed throughout the battle. The power levels of Goku and Gohan are very closely matched, and this still holds true today. Goku and his son would likely be equally matched against Beast Gohan, resulting in a fusion that balances their strengths and increases their power beyond Vegito.
Moreover, because Goku and Gohan share similar techniques, such as the Kamehameha, their combined abilities would synergize effectively. The father-son duo could potentially create new, unique techniques, similar to how Vegito demonstrated with the Final Kamehameha.
Goku and Gohan would also have the option to utilize their individual transformations, such as Gohan’s Mystic and Beast forms, while Goku can achieve Super Saiyan 3. With Gotenks capable of transforming into Super Saiyan 3, the fusion between Goku and Gohan could unlock a new level of power that would be incredibly formidable.
In conclusion, there is no doubt that the fusion between Goku and Gohan would surpass Vegito’s strength by a significant margin.
