MTV Movie Awards 2015: 'Avengers: Age of Ultron' Clip Shows Hulkbuster Fight (Video)

Robert Downey Jr. and the rest of the superhero team were on hand to pump the crowd up.

Robert Downey Jr. helped confirm some big Avengers: Age of Ultron speculation.

A clip that Downey brought to Sunday's MTV Movie Awards showed more of the much-anticipated Hulk (Mark Ruffalo) vs. Iron Man (Downey) fight, with dialogue showing that the angry green giant is under the influence of the Scarlet Witch (Elizabeth Olsen) during the battle.

"That girl is just messing with your mind. You're better than her; you're stronger than her. You're Bruce Banner," says Downey's Tony Stark. Fans had long speculated that the Scarlet Witch was controlling the Hulk during the battle.

Downey received the generation award during the MTV Movie Awards, where he was honored by co-stars including Chris Hemsworth (Thor), Chris Evans (Captain America), Scarlett Johansson (Black Widow) and Ruffalo.
