Seeing as the CopyCat Girl (Sorry I forgot her name), the one who masters anything she sees on TV, can master everything she watches on TV or her cell phone for that matter, has this unique ability. Wait I am getting ahead of myself, first let's lay down the rules of the show.
1. People Can Fly.
2. Manipulate the elements
3. The whole range of ESP abilities is a reality (Telekinesis, Precognition, Telepathy, Pyrokinesis (not yet proven in the show) etc.)
4. Longevity even immortality is a reality

Now if she were to watch The Matrix then she would acquire all of Neo's skills seeing as they fall within the limits of the show. Also what would happen if she were to obtain a recording of all the heroes in action, wouldn't she then acquire all of their powers just by watching them?
She could become quiet deadly, even Sylar & Peter wouldn't stand a chance against her, it would take all their combined powers just to put a dent in her. What do you all think?
