L'intervention de Végéta

Baby, as Gohan, finds Vegeta and Bulla driving along a highway. Vegeta notices something wrong with Gohan right away, and instructs Bulla to go home. Vegeta learns that Baby is a Tuffle who is possessing Gohan. Baby explains how the Saiyans stole the Tuffles' home planet and claimed it as their own. This forced Tuffle scientists to create a parasitic organism, and send it off into the far reaches of space. Baby, this parasite, possessed Dr. Myuu and forced him to create a body for him. Vegeta tries to stop Baby, and has the upper hand, but Goten shows up, and he is still possessed by Baby. The two Saiyan brothers are too much for Vegeta, and Baby takes control of his body. Meanwhile, Goku, Trunks, and Pan find the two-star ball. Now that they have all seven Black Star Dragon Balls, they head back to Earth. (Source: Wikipedia)
