- Danny Phantom: "what if... Undergrowth's powers had lasting effects on Sam" (Episode Urban Jungle)
after the Undergrowth events Sam goes through some strange moments, such as plants growing fast, tripping over air and even falling slower than usual, but it is when a ghost attacks that it becomes clear, when Danny gets badly hit Sam gets angry and changes in the same fashion as Danny, gaining a green and black dress like the one she had when possessed by Undergrowth along with the black eye marks, the only differences where she had black high heeled boots, her hair became longer and wild down to her hips with green streaks and thorny vines wrapping around her arms, legs and hips.
after getting over her shock she goes on to fight the ghost with Danny, after all is settled Danny helps her de-transform and they go to his parents lab to check out what happened to her, after a few tests they find that Undergrowth's unique plant powers along with Sam's own close connection to nature caused an imprint and merging of her D.N.A with his powers, just like what happened to Danny when he got his powers only less painful and dangerous, after some training Sam begins to help Danny fight against ghosts with her new ghost powers, using the Greek name Gaia for her hero name.
