"Welcome to Super Hero High" is the first webisode in the first season of the DC Super Hero Girls web series, and first webisode overall. It was released on October 1, 2015.
In front of Super Hero High School, Principal Amanda Waller greets the viewer and the crowd of students gathered in front the school in different languages while walking to the door and introducing the school. Star Sapphire, Green Lantern and Bumblebee then fly over the front lawn and into the school followed by Beast Boy after transforming into a deer and a cartwheeling Harley Quinn after Poison Ivy uses her vines to open the school's doors. Waller then mentions the school's advanced training curriculum, dedication to the arts and rigorous academic programs while Harley makes faces behind her. As she mentions the latter, the screen changes to inside a classroom where Miss Martian receives an A+ grade and turns invisible in excitement. Waller explains that these features are meant to develop students' superpower, (the Flash runs with the Cheetah) brainpower, (Frost holds a hologram of an atom in a classroom) and willpower (Hawkgirl catches and throws a ball in the school stadium) states the school's mission to turn students into the superheroes of tomorrow (a line of graduating students beside a Superman statue). She then welcomes the viewer to Super Hero High if one wants to "supercharge [their] education" (Green Lantern and Star Sapphire do target practice), "meet super friends" (a crowd of female students laugh together), and "make a super difference" (Bumblebee rescues a man about to fall off a window cleaning platform).
