Marvel Entertainment finally released the official teaser trailer of ‘Avengers: Age of Ultron’. Ultron is determined to bring down Captain America, Iron Man, Thor and the whole Avenger’s team.

The teaser not only shows how menacing their version of Ultron is, it also shows that the team is threading in the murky waters. Thor and The Hulk were also seemed to be fighting with Iron Man who has a new armour for his iron suit..

While the original plan was to show the trailer on next weeks Agents of S.H.I.E.L.D. TV series, the teaser had leaked on October 22, 2014. The Marvel then decided to finally release their teaser on October 23 as a response and Tweeted the news for their fans.

Ultron, an artificial intelligence without human conscience, had joined with the other villains to squash the Avengers. Tony Stark needed to use his Iron Man suit once again though he had renounced from superheroes’ duties in the Iron Man 3.

As appeared in the teaser, Ultron seemed to have built itself from Iron man’s discarded suits and boast that he had no strings in him and acts as his own. There was also a clip in a mountain and what seemed to be a Hydra.

What is not shown in the trailer but many had been considering is that Paul Bettany who voices Stark’s AI , Jarvis, is rumored to be playing the role of Vision. It is yet to know if Stark will actually sacrifice himself in the second installment of the Avengers, but if it does happen, Vision will be the next Iron Man.

Many can only guess what are the other story lines since shots of Thor and broken Captain America’s shield had been shown in the end of the teaser. Until May 15, 2015, most of us will only guess.
