If Goku was the last Saiyan, it would drastically change the Dragon Ball series and its storyline. Here are a few possible scenarios: 1. No Vegeta or Saiyan rivalry: Without Vegeta as Goku's primary rival, the dynamics of their relationship would be nonexistent. Goku might not have had the necessary motivation to surpass his limits and achieve new levels of power. 2. No Super Saiyan transformation: Goku's transformation into a Super Saiyan was triggered by the anger and loss of his close friends and family at the hands of Frieza. Without any other Saiyans to lose, Goku might never unlock this iconic transformation or tap into his full potential. 3. Lack of Saiyan lineage: Goku's Saiyan heritage played a crucial role in shaping his strength and abilities. Without other Saiyans around, his unique Saiyan DNA would become irrelevant, and he might not possess the same potential for growth. 4. Different villains and storylines: Since Goku wouldn't be battling Frieza or other enemies connected to the Saiyan race, the series might have focused on different villains and story arcs. Goku's battles and adventures could have taken a significantly different direction. 5. Earth-centric focus: As Goku was raised on Earth, his connection and loyalty to the planet would likely become even stronger. The storyline might have shifted to protecting Earth from various threats rather than exploring the Saiyan heritage as extensively. It's important to note that many of the key story elements and arcs in Dragon Ball are tied to the Saiyan race, so Goku being the last Saiyan would require substantial changes to the series. The absence of other Saiyans could impact character development and the overall scale of the Dragon Ball universe.

If Goku was sent to Avalice, the fictional world from the video game "Freedom Planet," it would result in a crossover of two distinct franchises. Here's how it might unfold: 1. New setting and characters: Goku's arrival would introduce him to the unique world of Avalice, with its different geography, creatures, and inhabitants. He would meet characters like Lilac, Carol, and Milla, the main protagonists of Freedom Planet, who possess their own abilities and personalities. 2. Saiyan powers in Avalice: Goku's Saiyan DNA and power level would make him an incredibly formidable force in Avalice. His abilities, such as flight, energy manipulation, and heightened strength, would be crucial in the battles against the series' villains, like Lord Brevon. 3. Collaborative battles: Goku's arrival might lead to teaming up with Lilac, Carol, and Milla to combat common enemies. Their combined forces and abilities would create exciting and dynamic fight sequences, showcasing their unique fighting styles. 4. Cultural exchange and training: Goku could also learn from the inhabitants of Avalice, exchanging knowledge and techniques. He might acquire new moves or fighting styles from the different species and martial artists in Avalice, thereby enhancing his own skills. 5. New threats and adventures: The presence of Goku in Avalice could attract powerful adversaries who are intrigued by his immense power. These new villains might have their own motivations and abilities, which Goku and his allies would have to overcome to protect Avalice. 6. Stepping away from Dragon Ball: Goku's time in Avalice would likely move away from the Dragon Ball universe's traditional themes and storylines. While he possesses immense power, the focus would shift towards the challenges and adventures specific to Avalice, exploring new narratives and character developments. Combining Goku's character with the world of Avalice would undoubtedly create an exciting crossover, blending the two universes' strengths and creating unique interactions and storylines for fans of both franchises.
