Hero of the Month: Supergirl is the second webisode of Season 2 of the DC Super Hero Girls webseries.
In Super Suit design class, the class watches Principal Waller make the Hero of the Month announcement. While Supergirl draws a horse, Wonder Woman cheers for her as she is announced Hero of the Month. Principal Waller explains that Supergirl hails from the planet Krypton, showing an image of her ship flying by the planet, and that she is one of Earth's newest Super Heroes, showing an image of Supergirl in the SHHS yearbook.
It then flashes to an interview with Poison Ivy, while she's lounging on a deck chair and being fanned by one of her plant monsters. Ivy comments on how she loves how Supergirl gets her powers from the sun, remarking how plant-like it is. It then goes to Harley, who swings on a trapeze in her room, who remarks how Supergirl's got a knack for making a dramatic entrance. It is followed by a clip of Supergirl crashing into the school when she first arrived. It finally goes to Batgirl in her lab, who explains how Supergirl always manages to pull through and save the day, showing a clip of her tying up Granny Goodness to a tree with a flagpole, during their previous battle with the Female Furies as well as using her heat vision to help her friends roast marshmallows after they fail to start a campfire.
Supergirl then flies by the school and lands on top, nearly slipping. As she gains her footing, Principal Waller repeats that she is Hero of the Month.
