After upper body strength failed against the Leg Robots who were destroying Jump City, Raven takes on her persona of Lady Legasus once more to save the world with the power of legs. She takes the broken team and trains their legs through rigorous exercises and leg lifting, and succeeds in transforming the old Teen Titans into the "League of Legs". They all receive new "League of Legs" identities which is as follows: Cyborg becomes "Thunder Thighs", Starfire becomes the "Incredible Quad", Beast Boy becomes "The Calf" and Robin becomes "Captain Cankle". With the new legs and names in place, the five members devise a frontal assault against the Leg Robots in Legasus Headquarters, and eventually spring to action returning back to the battle grounds of Jump City confronting the machines once more. The team eventually decide to disband once "Leg Day" was over, not before they show off their legs once more.
