The final piece of the Ultron puzzle is finally here. Well, somewhat. Much is still unknown about him (or it), but Marvel has finally given the android Vision his very own poster and his proper place in the Avengers photo op. With this, the chessboard is set and ready for what is expected to be one of the biggest blockbusters this month. But given how Joss Whedon, with the blessing of Marvel of course, has tweaked the story a bit, Vision's origin story and eventual role in Marvel Cinematic Universe.
