The LXD, otherwise known as The Legion of Extraordinary Dancers is an online dance series dedicated to depicting dancers as super heroes and villains, using their skills and choreography to "battle" each other. LXD is not only a means of showcasing the underground/underrated world of hip hop dance, but also to show how ideas can lead what was once impossible, possible. During TED, the creator of LXD, Jon Chu, talked about how he was introduced to hip hop dance and how he saw people spin on their hands and legs 80 times, contort their bodies, and perform stunts he didn't think people could ever do. From this, Chu created something that would forever change the dance scene.
