Starfire's happy life suddenly takes an abrupt turn for the worse when a large lump pops up on her forehead ... and that is just the beginning. As the days pass, her body begins to develop new mutations, making her feel horrible because she fears that she is turning into a monster. She more and more shies away from her friends and hides her new deformities under heavy clothing.Then the Titans receive an emergency call about Plasmus, who is ripping up a stadium in search of a nourishing sewer pipe. When the Titans engage him, they come to notice Starfire's problem for the first time. After Plasmus blasts off her protective clothes, exposing her mutations, Starfire flies off into space in shame. Thinking that she now has no home to return to, she attempts to find aliens whose mutations match her own, but in each attempt she is met with fear and revulsion. Her Teen caretakers worried about her and should've taken better care of her modify the T-Ship for space travel and set off after her, tracing her route through the alien planets she has visited.
Eventually, Starfire arrives on a strange planet where, following a violent encounter with a flesh-eating plant, she encounters a beautiful humanoid woman who sheds some light on her current condition: Starfire is undergoing the Transformation, the biological passing of Tamaraneans from prepubescence to puberty. Starfire's transformations were so bizarre because she is turning into a special type of pubescent called Chrysalis. But before Starfire can ask more, a cocoon forms around her, protecting her. And then the woman reveals her true self: she is actually a member of a hostile alien species who are specialized in hunting Chrysalises, whom they consider a special, if rare, delicacy.
But before for the Chrysalis Eater to be able to devour Starfire, her Titan babysitters arrive and interfere. Robin frees Starfire from her cocoon and shows her that she has reverted to her former appearance, though with one improvement: she can now fire starbolts out of her eyes. With this new ability, she blasts the Chrysalis Eater onto the surface, where it is devoured by the flesh-eating plant Starfire had met earlier. With the reassurance that the other Titans will always be her friends and take care of her, no matter how much she changes on the outside, Starfire returns home with her guardians taking her home to bed and happy once again. But then it is said that Beast Boy gained the chicken pocks... a lesson from this episode: remember teen titan fans, just because your changing do 'sent mean your turning different, it do' sent matter what you look like on the outside and no matter how much you change on the outside, you will always be beautiful on the inside and that's what true beauty is and starfire learned that lesson too.
