En Sabah Nur is the young mutant who will go on to become Apocalypse. He has only made one post-credits scene appearance so far - when he was played by Brendan Pedder in X-Men: Days of Future Past - but he has already shown enough to put him very high on this list of power rankings. In the one scene we've seen him in to date, he was using his massive telekinetic powers to construct the Great Pyramid of Giza in Ancient Egypt. He was intricately controlling thousands of tonnes of stone materials with absolutely no strain showing on his face whatsoever. You can only imagine just how powerful he will be in his next appearance in X-Men: Apocalypse - when he will be played by Oscar Isaac - which will occur thousands of years later, when his telekinetic power will have developed, he will have powers that haven't yet been shown on screen (telepathy, energy manipulation, technopathy etc) and he will be augmented with technology.
