Could Goku Black Use Kaioken? The Role of Learned Techniques in Dragon Ball

Dragon Ball enthusiasts often debate whether Goku Black could harness the Kaioken technique. This article delves into the nuances of this question, exploring why and how (Super Saiyan) Goku acquired and used Kaioken, and providing context around its limitations for Goku Black.

Understanding Kaioken: A Technique Uniquely Learned

Kaioken is indeed a technique that must be learned, much like the Instant Transmission and Spirit Bomb techniques, which King Kai of Universe 7 taught Super Saiyan Goku. Initially, only Goku learned Kaioken, allowing him to amplify his power to impressive levels, such as reaching 2 Kaioken power during his battle with Frieza.

Interestingly, Goku also combined Kaioken with Super Saiyan Blue for his fight against the powerful entity, Hit. This fusion of techniques demonstrates a versatile command over the powerful skill. The learning of Kaioken is attributed to its origin with King Kai, who initiated Goku in this innate ability unique to the universe's atmosphere.

Supreme Kai’s Exclusive Kai-Kai: A Special Ability

However, another form of the term "Kaioken" often confused with the technique is the Kai-Kai used by the Supremes Kais and their apprentices. This ability is more akin to advanced versions of visualization and telekinetic energy control. For example, the Surprise Kais use Kai-Kai to monitor and nurture the universe, while the God of Destruction eliminates what is no longer needed.

As a non-Surprise Kai, Goku cannot learn Kai-Kai due to his non-apprentice status. Any knowledge or ability held by Supreme Kais, including Kakarot’s transformation techniques, are exclusive to their lineage, much like how Luffy cannot learn the Devil Fruit abilities of Kaido.

Empathy and Access to Techniques: Kakarot’s Body and Training

Contrary to common belief, possessing Kakarot's body does not automatically equate to access to his techniques. The body mechanics and technique command must still be trained. As evidence, Vegeta, during his battle against Goku Black, asserts, "You might have Kakarots body, but you don’t know how to use it." This highlights that even with Kakarot’s form, Goku Black lacked the Kaioken technique.

Moreover, Supreme Kais have a strong emotional bond with their apprentices, as seen through Vegeta’s disappointment in Goku Black. Goku Black, being a reprogrammed version of Goku, may possess innate knowledge of the Hakai technique, but its use is constrained by the paradox of using another's form without proper training. It's akin to attempting to play a grand piano with a set of violin strings; the instrument, though recognizable, does not yield the intended results without the right skills and practice.

Conclusion: The Limitations of Kaioken Usage in Goku Black

In conclusion, Goku Black could not utilize the Kaioken technique despite possessing Kakarot’s form. The learnability of Kaioken is a critical aspect that differentiates it from other transformations like the Super Saiyan Blue or Ultra Instinct. While Goku Black may have the physical attributes, harnessing the full extent of the Kaioken required dedicated training, which he lacked given his unique origins and the exceptional circumstances surrounding his reprogramming.

Through this exploration, we deepen our understanding of the rich tapestry of Dragon Ball’s lore and the unique requirements of mastering certain techniques within the series.
