When Fat Buu initially emerged from his cocoon, he defied expectations and didn't appear immediately menacing. Although he swiftly defeated Gohan and killed Dabura, it was clear from Vegeta's earlier comments that neither of them posed a significant threat. Meanwhile, Vegeta had recently attained Super Saiyan 2 status through Babidi's powers, showcasing his peak strength by easily overpowering Goku in a fight.

Despite Vegeta being the first real challenge for Buu, it became evident that he was outmatched, and Buu's resilience made him nearly invincible. The significance of this battle lies not in its competitiveness but in Vegeta's unconventional resolution. Recognizing the formidable threat posed by Buu, Vegeta took drastic measures. He incapacitated Trunks and Goten, urging Piccolo to escort them to safety. Openly expressing his intention to sacrifice himself, Vegeta made this fight memorable by putting others ahead of himself.

In a self-destructive blast, he unleashed his power to eliminate Buu. In his final moments, Vegeta's thoughts were not about gaining more strength or his Saiyan pride but solely focused on saving his family, and even Goku.

The Buu Saga is often criticized for introducing over-the-top power levels and numerous transformations. However, it still had some standout moments, with one of the best being a non-Buu-related fight between Goku and his longtime rival.

Vegeta's constant desire to surpass Goku is well-known. After Goku sacrificed himself against Cell, Vegeta lamented that he would never get another chance to prove himself against his rival. Their inevitable rematch occurred when Vegeta, under Babidi's influence, attained Super Saiyan 2, putting them on equal ground. The catalyst for their clash was Vegeta's ruthless act of killing spectators at the World Martial Arts Tournament. Despite other visually impressive battles in the series, this one stands out for its emotional intensity. Each punch thrown by Vegeta carried years of built-up anger and frustration.

While Vegeta won with a cheap shot when Goku dropped his guard, the moment was remarkable as it showcased the return of Vegeta's dark side. However, the impact was somewhat diminished when it was later revealed that Goku had the Super Saiyan 3 transformation all along and had been holding back during the fight.

The significant impact of this confrontation, however, lay in Goku influencing Buu to break free from Babidi's control, resulting in Buu killing the wizard and becoming his own master.
