Goku has faced numerous battles throughout his adventures in Dragon Ball, but there are ten in particular that proved to be incredibly challenging for the powerful Saiyan. As the main character of this renowned action anime franchise, Goku naturally finds himself at the center of the most significant and impactful fights. While some of his battles have been relatively straightforward, particularly in the earlier parts of the series, there have been many encounters that have pushed Goku to his absolute limits, often requiring a miraculous effort for him to emerge victorious.
Although all of Goku's opponents have posed some form of challenge, there are ten fights that truly stand out as the most difficult he has ever faced. However, it is important to note that just because a fight was tough for Goku, it does not necessarily mean that his opponent is considered a powerhouse by today's Dragon Ball standards. This distinction is particularly relevant in light of the substantial power escalation that has occurred in Dragon Ball Super. While the level of power is indeed a significant factor in determining the difficulty of a fight, another crucial aspect taken into consideration is the extent to which Goku had to push himself to overcome the odds.
10 Goku Vs. Vegeta (Saiyan Saga)
Goku’s initial encounter with Vegeta during the Saiyan Saga holds immense significance, largely due to its portrayal of the true might of the Saiyan race. Vegeta's relentless attacks compelled Goku to continuously push his limits with the Kaio-ken technique, disregarding the toll it took on his well-being. Furthermore, what truly emphasized Vegeta's indomitable nature was the fact that Goku still ended up defeated. Despite infusing his Kamehameha with the Kaio-ken, Goku failed to vanquish Vegeta. Subsequently, when the antagonist transformed into a Great Ape, Goku found himself completely overwhelmed, necessitating the intervention of Gohan, Krillin, and Yajirobe to ultimately bring Vegeta down, albeit barely. Vegeta from Dragon Ball undeniably established himself as a formidable combatant, and even with his transformation into an ally, this fundamental aspect remains unaltered.
9 Goku Vs. Frieza (Namek Saga)
Few battles in the history of Dragon Ball are as iconic as Goku's epic showdown with Frieza during the Namek Saga. Frieza, known as the mightiest being in the universe, lived up to his reputation by dominating most of the fight. Even Goku's most powerful attacks only fueled Frieza's anger. Ultimately, Goku tapped into his hidden potential as a Super Saiyan to defeat Frieza. However, it is worth noting that Frieza's subsequent appearances in Dragon Ball Super serve as a constant reminder of the immense threat he poses.
8 Goku Vs. Cell
Another remarkable battle in the Dragon Ball series was Goku's encounter with Cell. Despite being portrayed as the sole hope against Cell in the latter half of the Android Saga, Goku quickly found himself outmatched when they finally clashed. This was further exacerbated by the revelation that Cell had intentionally held back during their fight. Although Gohan ultimately triumphed over Cell, it speaks volumes that Goku was unable to defeat him, solidifying Cell as one of the few adversaries Goku couldn't overcome.
7 Goku Vs. Kid Buu
Kid Buu was the ultimate antagonist in Dragon Ball, and he posed a formidable challenge for Goku. Despite the debate surrounding whether Kid Buu was the strongest version of Majin Buu, he proved to be a force too mighty for Goku to overcome using conventional methods. Recognizing Goku's inability to emerge victorious single-handedly, Vegeta, Fat Buu, and Mister Satan joined forces to assist him in generating an immensely powerful Spirit Bomb. This climactic showdown against Kid Buu marked a truly epic conclusion to the series.
6 Goku Vs. Beerus
Beerus proved himself to be Goku's first formidable opponent in the Dragon Ball Super era. Despite Goku's initial claim as the strongest character in the series, Beerus effortlessly defeated him in their first encounter. Even when Goku obtained the power of the Super Saiyan God, he could only push Beerus to use a fraction of his true strength. Ten years later, Goku is still far from surpassing Beerus' overwhelming power, making him the perfect catalyst for the new era of Dragon Ball.
5 Goku Vs. Goku Black
Many of Goku's toughest battles have been ones in which he faced insurmountable odds, with Goku Black serving as a prime example. In their initial encounter, Goku Black not only overwhelmed Goku and Vegeta but also grew stronger with each confrontation, making him increasingly difficult to overcome. Despite their best efforts, including Goku's, none of the heroes were able to claim a definitive victory over Goku Black. Ultimately, his defeat came about only because a literal god intervened, as he vanished upon merging with Zamasu to become Fused Zamasu. This highlights the extent of Goku Black's power and solidifies his status as one of the few adversaries in the series that the heroes could never conquer.
4 Goku Vs. Jiren
Dragon Ball Super’s Tournament of Power showcased Jiren as the unrivaled powerhouse, not only in the tournament but potentially in the entire multiverse. His dominance in every battle, effortlessly overpowering Goku and other contestants, solidified his reputation as someone surpassing even a God of Destruction. It was only when Goku tapped into the power of Mastered Ultra Instinct that he finally gained a slight advantage over Jiren. However, even years after the Tournament of Power, surpassing Jiren remains a crucial milestone for both Goku and Vegeta to achieve.
3 Goku Vs. Broly
Dragon Ball Super: Broly introduced Broly from Dragon Ball Z into the official Dragon Ball canon. As expected, he proved to be one of Goku's most formidable adversaries. Initially, Goku was able to overpower Broly when he activated Super Saiyan Blue. However, Broly's transformation into Super Saiyan gave him enough strength to completely overpower Goku, even with Vegeta's assistance. It was only when Goku and Vegeta fused into Gogeta that they were finally able to defeat Broly. This clearly demonstrates that Broly is undeniably one of Goku's strongest opponents, whether considered canon or not.
2 Goku Vs. Moro
Moro, the manga-original villain introduced in Dragon Ball Super, stands out as one of the most distinct and formidable adversaries in the series. Possessing magical abilities and the ability to absorb energy, Moro consistently outmatched Goku and his companions in combat, particularly after assimilating Seven-Three. His utilization of Merus' Angel powers to merge with the Earth propelled him to such an overwhelming level of power that even Beerus, the God of Destruction, deemed it necessary to intervene. Ultimately, Goku emerged victorious solely due to the collective energies of his allies, enabling him to tap into even greater power through Ultra Instinct. Thus, Moro rightfully earns his place as one of Goku's most formidable foes.
1 Goku Vs. Gas
Gas, the final opponent faced by Goku in the Granolah the Survivor Saga, proved to be the most formidable. Thanks to the power of the Cerelian Dragon Balls, Gas became the strongest fighter in the universe, easily overpowering Goku, Vegeta, and Granolah individually. Despite their combined efforts, Gas proved to be too overwhelming, forcing Frieza to intervene with his new Black Frieza form in order to defeat him. Without a doubt, Gas stands as Goku's most challenging battle in the Dragon Ball series thus far.
Goku undoubtedly possesses immense strength and fighting skills, but what truly captivates the audience is his constant struggle against formidable adversaries. The perpetual element of surprise in Dragon Ball lies in the unpredictable ways Goku and his companions manage to conquer the overwhelming threats to their lives. Ultimately, it is Goku's relentless battles that exemplify his resilience and contribute to the enduring popularity of both him and his series.
