The cast of "Avengers: Age of Ultron" surprised fans during Marvel's Hall H appearance at the Comic-con on Saturday by revealing a footage showing a montage of scenes from the "Avengers" sequel. One of the scenes highlighted in the footage was the fight between Iron Man and The Hulk. However, Mark Rufallo hinted that The Hulk also has a vulnerable side to him other than being angry all the time.

As previously reported by IBTimes, Iron Man will eventually follow Marvel's comicbook storyline and battle The Hulk. This is where Tony Stark's new armour comes in, the hulkbuster. Stark created the Hulkbuster specifically for the angry green giant so he can be defeated. Iron Man's Hulkbuster is reportedly "hulk-like" in nature since it is almost the size of The Hulk himself and also bulkier.

Marvel Studios president and producer Kevin Feige initially revealed a 2-minute footage during the Q&A for "Guardians of the Galaxy" in London showing the two heroes engaged in a fight. It is where the Hulkbuster was initially spotted.Now the footage from Comic-con revealed a much more thorough look at Iron man and Hulk's fight scene.

Comicbookresources reported The Hulk and Iron Man in his Hulkbuster armour took their fight scene in Korea. Hulk is seen throwing a sedan at the Hulkbuster. However Iron Man manages to catch it just for a split moment before Hulk came forward, crashing the car's head into his chest. Then Hulk delivers a heavy punch on Iron Man but the Hulkbuster's metallic hand was quick to intercept the blow. The sudden block caused Iron Man to reel back for a moment.

Speculations as to why the two heroes are fighting are linked to Bruce Banner not being able to control his alter-ego. There would come a point that Hulk would be too powerful to be defeated by any of the Avengers, unless of course, they have the Hulkbuster.

However, Movieweb revealed that Mark Ruffalo hinted on The Hulk as being not altogether the bad giant in "Avengers: Age of Ultron." The actor claimed his character actually has a vulnerable side to him.

"What makes Hulk afraid? It's himself. It's a version of himself that's weak. It's a version of himself that's vulnerable. It's a child inside of him," he said.

Mark Ruffalo said there would come a time where both Bruce Banner and The Hulk would learn to work together since they are both afraid of each other.
