Role in the Movie
In the film, Rainbow Dash and the Wonderbolts are in charge of weather for the Festival of Friendship in Canterlot. When the city is invaded by the Storm King's forces, led by Tempest Shadow, Rainbow and her friends escape to seek out the "Queen of the Hippos"—later specified to be Queen Novo of the Hippogriffs—for help. During their time on Captain Celaeno's airship, Rainbow convinces her and her fellow pirates to rebel against the Storm King and return to their swashbuckling ways, but she accidentally draws Tempest's attention with her sonic rainboom. In the underwater kingdom of Seaquestria, Rainbow and her friends almost convince Novo to help them save their home from the Storm King, but Twilight's attempted theft of Novo's Pearl of Transformation gets them banished from Seaquestria.

Rainbow Dash and the rest of the Mane Six have a falling-out with Twilight over her actions, but they—along with other friends they made during their journey—return to Canterlot to rescue her when she gets captured by Tempest. After sneaking into the city and fighting past the Storm King's forces, the Mane Six reunite and make amends, and they eventually succeed in defeating the Storm King. In the end, the Friendship Festival resumes, and Rainbow and her friends befriend Tempest.
