For those of you who have watched Dragon Ball, you should remember Launch or "Lunch". I found her character to add a bit more humor to the story in a different way. Given the fact that she had some kind of split personality disorder that manifested both mentally and physically with a sneeze always make her character easy to place in different situations. She was very prevalent in Dragon Ball but only seen a few times in Dragon Ball Z by way of the Vegeta Saga and during the Kid Buu Saga where she is shown giving energy to Goku's spirit bomb.
Would you have liked her to stick around in the story more?
