There's no question that "The Avengers: Age of Ultron" is one of the most anticipated movies coming out this year. While epic action sequences are expected, fans need to take heed: spoilers are pointing to a tragic death in this second instalment and it can be heartbreaking. 

There's a rumor going around that one of the Avengers may take one for the team in "Age of Ultron." It is said that this Avenger is actually one of the founding members of the superhero team, which, if true, just makes the loss more tragic.

The news comes from Marvel Movies Wiki where rumors and spoilers for "Age of Ultron" are listed out.

One of the spoilers says, "Hawkeye fires an arrow at Ultron from an exploding Quinjet filled with drones, sacrificing himself to hit him with a USB arrow that uploads a virus created by Stark into Ultron's system." 

An Avenger sacrificing himself isn't something out of the ordinary, but if this is the way Hawkeye is going out, it's highly unlikely. Hawkeye simply dying from an exploding plane will not do his sacrifice justice.

Further, this theory is debunked by a rumor on the same page, saying, "Hawkeye is not the major character that may die."

Then again, does this mean that there will be a major character who will die? 

Still, Hawkeye's alleged death isn't the most surprising thing. The rumor also says, "Captain America wields Thor's hammer and destroys Ultron's enhanced body. Ultron tries to jump to other robotic bodies, but Quicksilver destroys them one by one in a matter of seconds, and Ultron ends up trapped in an old Iron Man armor, which is promptly destroyed." 

How is Captain America able to wield Mjolnir? If he does, then what happened to Thor prior to that?

In an extended preview, the team is making fun at who can lift Mjolnir and only the Captain is able to nudge it a bit. No one knows if the Captain will actually wield the hammer during the fight. 

Moreover, the death of Ultron is revealed here, with a big help from Quicksilver. Ultron trapped in an Iron Man suit that is set to explode is a smart move. It does make sense after all. If true, then the death of Ultron signifies his return to his maker. 

"The Avengers: Age of Ultron" hits theaters on May 1.
