Throughout the years many mutants in Marvel have gone through changes . Their powers have increased or appearance has drastically change via secondary mutations. The X-men's Beast is the most obvious example as he started as a man-ape changed to an ape-man and now is a giant house cat. Ice-man also has changed from a walking snowcone to a truly man made of ice. Some have gone through change but not in appearance but rather in power. They have gained extra powers and or lost powers , and of course become more powerful or less. This makes me wonder what might the most popular mutants in marvel look like and how will their power levels change in the future. Scarlet Witch for one I see becoming less human and more of an entity. She has almost always been shown in constant struggle with her powers and has been on the edge of insanity often on recent years. I see her becoming almost abstract or as her powers take over. Quicksilver. I see him becoming unstable on a molecular level. He may become a being of pure energy as his human body pulls itself apart. Magneto I see becoming so powerful that he even becomes a danger to himself. He will then need to be in a constant state of concentration in order to control his power and to keep from destroying the world around him. Charles will help but in the end Magneto will finally understand why humans have feared mutants and then will make himself self destruct in order to save humanity and mutants alike.
