Launch’s character was phased out as the series progressed, with her last appearance in the manga being during the Saiyan saga.
Launch was a woman with a peculiar disorder that caused her personality to shift from a sweet, blue-haired woman to a violent, blonde-haired bandit whenever she sneezed. Created by Akira Toriyama, she was a prominent character in the original Dragon Ball series. However, as the series transitioned into Dragon Ball Z, Launch’s appearances became less frequent, and eventually, she disappeared from the series altogether.
The reason for her disappearance is not explicitly stated within the anime or manga, but Akira Toriyama later explained in interviews that he simply forgot about the character as the series continued to evolve. The focus of Dragon Ball Z shifted towards more intense battles and power levels, which didn’t leave much room for Launch’s comedic relief.
In the anime, Launch is last seen in the filler episodes of Dragon Ball Z, where she is often shown chasing after Tien Shinhan, whom she had developed feelings for. Despite her absence from the main storyline, Launch remains a beloved character among the Dragon Ball fan community, and her unique personality and design are still celebrated.
