Look out for Launch!

Because Krillin can't sit on the Nimbus Cloud, he is forced to cling to Goku's back during their search for a girl. They find a girl being attacked by two men. Goku beats up these two guys, and they bring the girl back to Master Roshi's island. Unknown to either of them, the girl, Launch, was actually being arrested when they found her. When she sneezes, she turns into a mean, aggressive, blonde criminal. Back on the island, Roshi likes Launch so much that he agrees to take her on as a student, along with Goku and Krillin. Launch sneezes, and then takes out a machine gun and shoots at the three boys. After another sneeze, everything is back to normal.
