Okay, as we've seen the Quicksilver and Scarlet-witch picture in the upcoming blockbuster Avengers: Age of Ultron there is always a possibility for our favorite Magneto's appearance in the movie. Though it's yet not confirmed by the Avengers franchaise but as we now know that the [Quicksilver and Scarlet Witch](movie:1081109) are the children of Magneto the possibility remains. As Joss Whedon planned too many cast and crew for the [The Avengers: Age Of Ultron](movie:293035) so we can't expect Magento in Age of Ultron . It will be huge if we are having Magneto for Avengers 3. No sign of this amazing thing by the actor Ian Mckellen has appeared yet. But it is abosolutely sure Marvel is planning something big for [The Avengers 3](movie:738027).
