Image via WikipediaI have heard a rumor that there does exist a version of the son of Magneto in MUGEN. There is even a video of Quicksilver in action. However, I'm not sure who made it and I am also not sure when or if it will ever be released. If anyone has any information, please feel free to comment below. The video shows a great character and I hope the developer(s) will decide to share it soon.
