Frieza appears to be strategizing to employ the Cube Spaceship for a journey to Universe 6, intending to exact revenge on Goku and Vegeta by conquering the Saiyans there. In Universe 6, Frieza perceives minimal opposition, judging its fighters to be weaker compared to Goku and Vegeta, with Legendary Super Saiyan Kale as a potential exception. While it remains uncertain whether Frieza is aware of the Cube Spaceship, speculation suggests he may have acquired this knowledge through Frost or his ties with Beerus. The forthcoming Dragon Ball Super arc promises to unveil Frieza's true intentions and plans.
The Tournament of Destroyers sparked speculation on why Black Frieza spared Goku and Vegeta in Dragon Ball Super. His return in the Granolah the Survivor Saga marked a long-awaited moment for fans, yet his decision to spare the Saiyan duo, despite his newfound superiority, left many puzzled. Frieza hinted that his focus lay elsewhere, teasing a deeper motive that remained unexplained but hinted at in earlier chapters.
In Chapter #12 of Dragon Ball Super by Akira Toriyama and Toyotarou, Vados from Universe 6 informs Champa, her God of Destruction, about persuading Hit to join Universe 7's tournament with the promise of a Cube Spaceship. This advanced vessel, capable of inter-universal travel, piqued interest, although Hit opted not to claim it after his battle with Goku. Nevertheless, its potential significance lingered, suggesting Frieza might covet it for a grand scheme.
Speculations arose that Frieza could leverage the Cube Spaceship to conquer Universe 6's Saiyans, mirroring his past conquest in Universe 7. This scheme would be a devastating revenge against Goku and Vegeta, who had previously dismantled Frieza's empire. Despite his ability to easily overpower them on planet Cereal, Frieza's plan might face challenges from figures like Hit and potentially Kale, the Legendary Super Saiyan.
However, uncertainties remain. Frieza's awareness of the Cube Spaceship is questionable, as his introduction to the series postdates its mention. Clues suggest he might have gleaned knowledge from allies like Frost or through his connections with Beerus. Whatever the case, Frieza's unexpected mercy towards his longtime foes hints at a larger, more sinister plot unfolding in future arcs of Dragon Ball Super.
As the series progresses with the conclusion of the Super Hero arc, fans eagerly anticipate Frieza's return and the revelation of his true intentions. His next move promises to challenge Goku, Vegeta, and possibly other characters like Broly and Gohan, pushing them to new limits in their quest to thwart his malevolent plans.
In summary, Frieza's sparing of Goku and Vegeta seems to be part of a broader strategy aimed at executing his most cunning scheme yet, possibly involving the Saiyans of Universe 6 and the mysterious Cube Spaceship. The upcoming arcs of Dragon Ball Super are poised to unveil the full extent of Frieza's ambitions and the ensuing battle that will shape the fate of the Saiyan universe.
