S1, E40: The Lightning League stops on a planet to warn its two occupants of Monster Minds taking over the galaxy. Selena has the rare gift of song -- she can sing anything into being, or destroy it. She and her father come to this deserted planet to escape those who would use her gift for evil. Of course, Saw Boss is hot to have her and he snatches her father to blackmail her into singing the destruction of Jayce. However, she chooses a song of destruction for she will not use her gift for evil no matter what. Saw Boss flees. She warns Jayce to go, but everyone joins hands and they all sing to help her restore the planet once again. Her father rejoins her unharmed.
