Marvel continues to deepen the mystery of "Mosaic" in their latest teaser, which adds a Stark Tech-inspired piece to the puzzle. The new puzzle piece -- which looks as though it belongs to the bottom left-hand corner of the complete image -- features an appearance by Iron Man or War Machine on the left, though the color scheme makes it unclear which character it truly is.
