Calling all aspiring super heroes:  Megan Nicole wants you to "Get Your Cape On." The YouTube sensation teamed up with Warner Bros. Consumer Products and DC Entertainment to record a brand-new DC Super Hero Girls theme song, encouraging you to embrace your inner warrior.

The song kicks off a season of activity for DC Super Hero Girls that is inspiring fans to support others through teamwork, friendship and words of encouragement. Be on the lookout for a Halloween costume challenge, community-based activities during the holiday season and more.

So grab your cape, crank up the volume and sing along with the video above. And don’t forget to show how you “get your cape on” by posting pictures to social media using #GetYourCapeOn and #DCSuperHeroGirls.
