It looks like Pepsico (NYSE: PEP) has a superhero coming to its aid.

The company's stock has been quite volatile recently, dipping 7% this past February before rallying back throughout March. But Pepsi's stock rose 0.5% on Monday after the company-owned Mountain Dew announced a partnership with the upcoming film The Dark Knight Rises.

According to MarketWatch, Mountain Dew will distribute a limited-edition mixed-berry flavor inspired by the film. The company will also provide exclusive content to viewers through a digital experience before opening day.

The partnership could draw thousands of Dark Knight fans to the soda company. The latest installment, The Dark Knight (2008), broke box-office records with a $158.4 million opening weekend and raked in more than a billion dollars worldwide, according to Box Office Mojo.

Mountain Dew senior marketing manager Zach Harris states that "Mountain Dew is always looking for partnerships that are meaningful to our consumers and that we can customize to increase value for our fans."

The new Mountain Dew Dark Berry will be available for eight weeks, starting in mid-June.
