A new extended trailer was released, this time revealing more about Ultron than it did before. The trailer starts with Ultron interrupting a party of some sort where he brings some of his friends with him to attack all our superheroes who are present.

For those who don't know who Ultron is, well he is the Avengers prime nemesis and one of the chief super villains of Marvel. Though it isn't clear what Ultrons goals are, one thing is for sure, he wants to destroy the avengers and take over the world (or something like that). It isn't clear either where Ultron come from but according to Entertainment Weekly, he is a creation of Tony Stark. Ultron is more of a consciousness rather than a physical being that can transfer from one automated thing to another. When Stark created Ultron, he infused it with some of his unpleasing personality which only makes the matter worse.

We can also see new faces, that of Quicksilver and Scarlet Witch. So far, it seems that these two are one of the bad guys too although that remains to be discovered if it's really the case. Quicksilver seems to have the power of super-speed and it looks like Scarlet Witch can manipulate kinetic energy.

There is also a part of the trailer where a very huge Iron Man is fighting against Hulk. Although it's not yet confirmed if Tony Stark is inside that armor, but from the looks of it, maybe it is him inside that suit. There is also that slight possibility that Ultron is controlling that thing resulting to Hulk fighting against him. Speaking of Hulk, it looks like he has something going on with Black Widow since we can see the two touching hands in a romantic kind of way. So that is a must see for all the Hulk fans out there.

From the trailer, it surely looks like the Avengers are in for a tougher fight compared to the first movie. It's a must see movie indeed, especially to those superhero fans out there.
