Since he was introduced in Dragon Ball Z, Vegeta has been responsible for some of the worst things to happen in the world of Dragon Ball. While the character has converted to the side of good, that still hasn't stopped this battle-thirsty Super Saiyan from doing acts of evil. From destroying an entire planet of aliens to letting a villain reach his final form, these are ten of the worst things that the Prince of all Saiyan has ever done in Dragon Ball Z.
10 10) Kicking Dende, after he healed him
Kicking off this list(literally), we start by showing how ungrateful Vegeta can be. When Vegeta demands that Krillin blast him to near death, the earthling obeys, knowing that this was the best chance they had. After Krillin complies, he tells Dende to heal Vegeta. The Namekian boy is hesitant since Vegeta has killed much of his race. However, he regretfully heals Vegeta, only for the Prince to kick him to the side.
9 9) Killing Burter and Recoome when they were down and out
While Goku has killed plenty of villains in his time, he only does so when his opponents leave him no other choice. Vegeta has never been as merciful. He's killed just about anyone that he feels is beneath him. He's even killed people when they were no longer a threat. After Goku does quick work of Burter, he tells Jeice to take the self-proclaimed "fastest being in the universe" to leave Namek and never return. However, Vegeta comes out of nowhere and knee's Burter in the neck. If that's not enough, he then goes on to kill Recoome too. Sure, they're both bad guys, but even they didn't deserve to be taken out when they were already down.
8 8) Killing Nappa
Nappa has been by Vegeta's side since he was only a child. When his home planet was destroyed, Vegeta thought that only he, Nappa, and Raditz were the only Saiyans left. While Radiz fell by Goku and Piccolo's hands(or fingers), Nappa was killed by the man he helped raise as a child. After Goku cripples Nappa with his Kaioken attack, Nappa begs Vegeta to help him out. While it looks like Vegeta is about to give him a hand, he quickly tosses him in the air before obliterating him in seconds. If that's not messed up, when villains escaped from Hell in GT, Vegeta once again blasted away his old partner
7 7) Beating up his son
When Dr. Gero escapes from the Z-Fighters, Trunks pleads to his father to wait for Goku to back them up. Vegeta, being the smug prick he is, says that they don't need Goku and that he'll destroy Gero and his androids in no time. Despite Trunks's continue pleading, Vegeta gets fed up and punches his son in the gut and tells him to stay out of his way. Oh, and let's not forget that time when he attacked Trunks when he tried to stop Cell. If only there were some Super Saiyan powered Child Services to help Trunks out.
6 6) Sucker punching Goku
During their long-awaited rematch, Majin Buu's awakening interrupts the dueling Saiyans. While Vegeta tries to convince himself that the demonic being is not a threat, Goku makes Vegeta come to an agreement that they need to put their fight on hold. As Goku is about to give his rival a Senzu Bean, Vegeta knocks him out so he can defeat Majin Buu and so Goku won't get any of the glory.
5 5) Letting Cell achieve Perfect form
While Vegeta's pride is what pushes him to be a better fighter, it's also his greatest weakness. It makes the Prince of all Saiyans cocky; he can't help but have his curiosity of a potentially powerful opponent be answered. When Vegeta humiliates Cell in his first transformation, Cell is furious that he couldn't achieve his Perfect form. When this prosper of Cell being even stronger catches Vegeta's interest, he lets Cell search for 18 and obtains the form. He even gives Trunks a beating. Well, Vegeta paid the price for doing so, cause Cell got his revenge for Vegeta embarrassing him by showing off his Perfect form.
4 4) Letting Babidi control him
The evil Babidi has the power to not only influence those with dark hearts to his side, but he can also give them an enormous power boost. When Vegeta sees this on display with Spopovich, and see's how strong Goku has become, He allows the evil wizard the chance to take control of him. While Vegeta is able to keep his free will, the proud Saiyan "Sells his soul to Babidi" in his quest to overcome Goku.
3 3) Killing Namekians
While Vegeta has slowly shifted his alliance to the Z-Fighters, that still doesn't eliminate all the terrible things he's done in the past. When searching for the Namekian Dragon Balls, Vegeta comes across a village in the middle of nowhere. Believing that the people of this small suburb have a Dragon Ball, he demands that the people give it to him. When they don't comply, he kills the innocent beings before the group finally gives Vegeta what he wants.
2 2) Killing innocent people at the World Tournament
After becoming the evil Prince that he was when he first met Goku, Vegeta demands that he and his arch-rival do battle once more. Since Goku was only going to be around for one day, Vegeta saw this as his only chance to face off against him. To assure Goku that he's dead serious, Vegeta does the unthinkable and kills numerous innocent people. If that's not enough, one of the blasts bearly misses Bulma and the gang. That's right, Vegeta was so desperate to get that rematch, not only did he let Babidi awaken the evil within him, but he also nearly killed his wife. Did we forget that Trunks was there while he did all that?
1 1) Destroying an entire race
While this little adventure was only a filler episode, it's no less the absolute evilest thing that Vegeta has ever done. When he and Nappa begin to get antsy on their trip to earth, the duo decides to stretch their legs by landing on the planet Arlia. The planet is in the midst of civil war, with its ruler thrown in the dungeon, and its new monarch is running a brutal dictatorship. Vegeta and Nappa, being the "Good Guys," decide to overthrow the evil ruler for the fun of it all. After they leave, we see the original ruler running happily towards his bride. However, while this is happening, Vegeta has already grown bored of Arlia and destroys the planet, just as the king and would-be queen reunite.
