Avengers: Age Of Ultron - 15 Theories That Were Utter Bull

15. Ultron Would Control The Hulkbuster

The Theory: Ultron would infect the Hulkbuster's tech and go on a rampage, leading to the Hulk having to intervene as the only Avengers capable of beating it in a fight.

The Supposed Evidence: Why else would he be fighting the Hulk in the trailer?

The Reality: Nothing of the sort.

As soon as the first trailer showed Hulk with his red eyes and furious anger, a lot of fans called that he would be the one losing his cool and rampaging. They were right, but not as many correctly guessed that Scarlet Witch would be behind his loss of control (or at least, not until the LEGO tie-in line spoiled it for everyone who saw it).

While Ultron was capable of controlling technology, for some reason he seemed less bothered about doing so to the Avengers' gadgets, which would have made it a lot easier to win. Hindsight's a wonderful thing.

Would It Have Been Better? Possibly. It would certainly have made more sense than Ultron just ignoring the Avengers tech. But then, it is always compelling to see the Avengers fight each other.
