Dragon Ball Z - episode 85 - 02 Apr, 1991

Despite his dramatic increase in power, Vegeta is no match for Frieza. It seems that he is not a Super Saiyan after all. Gohan, Krillin, and Piccolo helplessly look on in horror as Frieza incapacitates Vegeta and tortures him. Luckily, Goku has finally recovered. He breaks out of the healing chamber, and flies to the battlefield. (Source: Wikipedia)
