Transformations in Dragon Ball have a special place in the hearts of fans of the franchise. The first time a new form gets unveiled is often the result of many, many episodes of hard work and a lot of screaming on the part of the voice actors, so it is always a pretty big event. Many old-school fans can remember the first time Goku achieved Super Saiyan on Namek or the reveal of Super Saiyan 2 during the Cell Saga. Those moments manage to be at the top of memorable moments lists going back to the beginning of the series.
