This is the second Hulk from the Minimates Avengers Age of Ultron wave of figures and this is for the scene where the Hulk is enchanted by the Scarlet Witch and starts rampaging. If you notice, his skin almost looks grey in color, along with the red eyes. Marvel actually said they were considering the Hulk to turn actually grey during that scene but decided against it. Maybe the figure was finalized and put into production before they changed their mind. This Hulk came with the Hulkbuster Iron Man figure who he fought in the scene.
