Marvel has just released its fourth trailer to the much-anticipated film “Avengers: Age of Ultron.” Some of the scenes were already featured in the third trailer, but this time it shows all the Avengers, (Scarlet Witch, Quicksilver, Black Widow, Thor, Iron Man, Hawkeye, Captain America and Hulk) join forces to battle Ultron. It also shows Hulk going all out with rage on the villain’s army of robots.

Marvel has released an animated GIF from a scene in the trailer for “Avengers: Age of Ultron” that features Hulk (Mark Ruffalo) getting his hands busy destroying Ultron’s army. Although this scene was briefly revealed in the fourth trailer, Marvel thought it’d be a treat for fans to have it relieved in slow-mo. The GIF was shared via The Avengers Twitter page and was captioned, “Smashing through this week, Hulk-style. #Avengers #AgeOfUltron, in theaters May 1!” The post has since received 3, 279 likes with 2, 569 retweets.

There have been speculations of the green angry giant turning grey in “Avengers: Age of Ultron” ever since PopVinyls.com shared a photo of a grey Hulk as one of the movie tie-in merchandise. Although the grey Hulk may not directly represent the character in the sequel, Cinema Blend claimed there’s still a possibly that Bruce Banner’s alter-ego could still turn grey with the help of Scarlet Witch’s powers.

According to Vanity Fair, Wanda Maximoff a.k.a. Scarlet Witch has the ability to create an alternate version of reality and even control those people around her. It’s believed Hulk turning grey is a curse or a hallucination placed upon him by Scarlet Witch. Cinema Blend added the grey version of the Hulk is much more out of control and more savage than his normal self. It’s interesting to wonder how more savage Hulk could get considering that in the GIF he already looks so enraged as he beats down on Ultron’s robots even in his usual green colour.

It’s still uncertain if Hulk will be turning grey in “Avengers: Age of Ultron,” but Mark Ruffalo once hinted of the possibility of Scarlet Witch controlling him. When asked by IGN if Scarlet Witch "able to just call up the Hulk and control him,” Rufallo replied, “"She's able to bring out the worst in us."
