A Heart of Evil Awakened; Vegeta, Prince of Destruction Dragon Ball Kai: Doragon bôru kai : Season 5 Episode 15

As the battle between Gohan and Dabura continues, Vegeta's impatience to settle things with Goku catches the attention of Dabura, who decides to abandon the fight and report to Babidi. Learning that Vegeta still retains a lot of evil in his heart, Babidi uses his magic to target Vegeta's mind and sway him over to his side. To make matters worse, Babidi transports everyone to the tournament grounds, where Vegeta, still focused on his desire to defeat Goku, prepares to face off against him, even with innocent bystanders watching.
