10 Things That Must Happen In MCU Phase 3
8. Peter Parker Uses The Iron Spider

Peter Parker ends up being gifted his iconic Iron Spider armour by Tony Stark, which of course enhances Spidey's pre-existing powers in every way while granting him spider-like tentacles and a host of other nifty additions.
Considering that Spider-Man: Homecoming will see Parker and Stark teaming up, and the movie may see Spidey take on The Vulture, it'd be the perfect film for the web-slinger to bust out the enhanced suit.
How Likely Is It?: This is a tricky one. Marvel may want to spend Spidey's first solo movie dealing with him as a more conventional iteration of the superhero, but one could easily see the armour show up in Infinity War when the battle ratchets up.
It would be a smart and potentially awesome way to one-up Spider-Man from previous cinematic iterations, and considering the subversive creative choices Marvel Studios have made so far, we'll optimistically bank on it for Infinity War. 6/10
