Depiction in the seriesSerenity first appears in Hurricane Fluttershy as one of the Pegasi helping transport water from Ponyville to Cloudsdale. Throughout his scenes, Serenity's mane color switches between blue and yellow. During the second tornado attempt, Rainbow Dash shouts at him to "flap those wings", and he has a brief speaking role asking "What was that?" when Fluttershy passes him.
Serenity appears later in Rainbow Falls flying about the Equestria Games qualification tryouts in much the same way as his first appearance. In Equestria Games, he flies up with other Pegasi to stop the ice cloud from falling onto the stadium.
In season five, Serenity appears in Tanks for the Memories moving clouds from Cloudsdale to Ponyville for winter.
