The untold reason behind Vegeta's deep-seated resentment towards Goku revealed
Goku and Vegeta, the iconic duo of the Dragon Ball brand, were once bitter foes before becoming allies. Their first clash, during the Saiyan saga, played a pivotal role in shaping their future.

In the Saiyan Saga, Vegeta, the antagonist bent on destroying Earth, faced off against Goku, the only one capable of challenging him. Despite Goku's defeat, Vegeta found himself immobilized due to injuries, giving Krillin a chance to eliminate him. Surprisingly, Goku spared Vegeta at Krillin's request.
During the Majin Buu Saga, Vegeta harbored intense resentment as Goku not only saved him but also grew stronger. Yielding to Babidi's magic to enhance his power, Vegeta demanded a rematch with Goku to prove his superiority.

Vegeta revealed a deliberate choice to succumb to Babidi's control, driven by a lingering sense of humiliation from Goku sparing his life years ago. In Vegeta's view, he should have embraced sacrifice as a proud warrior rather than being saved by someone he considered inferior.
Goku's hidden compassion unwittingly fueled Vegeta's transformation into Majin Vegeta. Despite later acknowledging his mistake, Vegeta's lingering resentment serves as evidence of the profound impact left by the first clash between the Saiyan warriors. Alongside this, Dragon Ball solidified Goku's greatest adversary, his companion in battles, the monkey prince, up to this day.
