Joss Whedon Announces Revealing ‘Avengers 2′ Title at Marvel Comic-Con Panel

Marvel, the studio that brings us the biggest superhero movies around, brought the big guns to Comic-Con's Hall H tonight.

There was a ton of big stuff – including first looks at "Captain America: The Winter Soldier" and "Guardians of the Galaxy" – but the biggest news is that we now know the reason the "Avengers" team will be reassembling in 2015.

Joss Whedon concluded the panel by introducing a teaser trailer showing what appeared to be Iron Man's mask getting beat up from unseen forces, with the voices from "Marvel's the Avengers" talking about how they aren't a team, they're a "time bomb," and the like. But soon a pan-out reveals the mask is not Iron Man at all. And just as you're wondering who it is, a graphic flashes across the screen: "Avengers 2: The Age of Ultron."

Boom! Lights up. The crowd goes wild. And every geek around was shaking in their seats.

Why you ask? Because Ultron opens up a world full of possibility.

"The Age of Ultron" is a Marvel Comics ten-issue run written earlier this year, which centers around the robot Ultron, who was created by Hank Pym aka Ant-Man, aka the movie Marvel is releasing in November, 2015. Pym uses his own brain waves and adamantium (the stuff that makes Wolverine tick) to create the robot.

Since it's the comics, there's tons of back story, but basically, Ultron has daddy issues, becomes self-aware, rebels against his maker, then brainwashes Pym to forget about making him in the first place.

Empire Magazine tweeted after the panel that they had spoken with Marvel Studios head Kevin Feige, who said the title is "borrowed" from the comic book run, but "bears no relation to the run.

Which would make sense, since the "The Age of Ultron" run takes place after Ultron and his Sentinels have already conquered the world. And we'd want to see that, right?

Also, "Avengers 2" comes out in May 2015, before "Ant-Man," so it would certainly makes one wonder how Ultron fits into that picture, since he would have been destroying earth six months prior.

Also complicating the matter is that "The Age of Ultron" run features Wolverine and the Fantastic Four – properties of 20th Century Fox – as well as Spider-Man – a property of Sony. Though Andrew Garfield did say he'd love to join the Avengers, as it's been portrayed plenty in the comics.

So we know a title. And we know the story will prominently feature Ultron, who has a long rich history in the comics, ranging all the way back to Avengers #54 in 1968. Perhaps Marvel will focus on the fact that Ultron created the android Vision, a future Avenger who kinda looks a little like Vin Diesel in a green suit and red make-up.

Whatever direction Marvel decides to go for "Avengers 2: The Age of Ultron," they won't have any trouble filling up Hall H at next year's Comic-Con to talk about it.
