‘Avengers 2’ title revealed

(CNN) -- Prepare yourself for the Age of Ultron.

Joss Whedon surprised the crowd at the end of the Marvel panel at Comic-Con to reveal this as the title and main character of Avengers 2.

We'll get to that. We promise.

But first the Marvel crew ran down all the major titles coming up, including new details on "Thor: The Dark World," "Captain America: The Winter Soldier," and "Guardians of the Galaxy."

Here's how it happened:

Kevin Feige is introduced as "the master of nerd puppetry" by moderator Chris Hardwick.

Asked what he has in the works, Feige says: "Well, we have a movie called 'Thor: The Dark World.'"

A cavernous boom! And then total darkness as the billboard-sized screen in 6,000-seat Hall H goes blank.

"Humanity ... look how far you've fallen. Lining up in the heat ... chattering together in the dark ... LIKE BEASTS!!!"

Aaand LIGHTNING FLASH as Tom Hiddleston appears in character as Loki.

Thor: The Dark World

"Stand back, you mewling quim!" He declares. And everyone falls down in fealty, cheering.

"You should have let me rule you when you had the chance."

Hiddleston, er, Loki unleashes an Asgardian-style Don Rickles routine, insulting the miserable mass of humanity before him. Then asks: "Say my name?"

LOKI!!! the crowd roars

"Say my NAME!" he says, no longer asking.

The crowd chants: LOKI ...! LOKI ...! LOKI ....!

Hiddleston smiles: "Then I have an army."

A clip of "Thor: The Dark World" begins to play, showing Chris Hemsworth's hammer-swinging hero in an epic, galactic battle.

At one point, Natalie Portman's character appears to slap Loki. "That was for New York," she says.

Again, Loki smiles.

The clip ends and bow power has been restored. Feige begins introducing the cast of "Captain America: The Winter Soldier," which has one more week to shoot.

Captain America: The Winter Soldier

Unknown thugs gather in an elevator and Steve Rogers can tell something is wrong. One of them is Frank Grillo as the villain Crossbones. "Before we start," Cap says, "Anyone want to get out?"

A face-crushing fistfight breaks out, and all fall except Crossbones.

"I just want you to know, Cap. None of this is personal," he says.

"It kinda feels personal," Rogers says, and the battle continues.

"To build a better world sometimes means tearing the old one down," says Robert Redford's voice. He appears against a large window, Alexander Pierce, "Disorder, war, all it takes is one step."

Now Samuel L. Jackson's Nick Fury speaks: "We're going to neutralize a lot of threats before they happen."

"I thought the punishment usually came after the crime," Cap says.

"S.H.I.E.L.D. sees the world as it is, not as we hope it to be," Fury replies.

The last shot is Sebastian Stan's Winter Soldier, picking up Captain America's fallen shield.

Guardians of the Galaxy

Now, Feige reveals that the upcoming space saga "Guardians of the Galaxy" has just started shooting in the U.K. and wanted to come to Comic-Con. "So they decided to come ...!"

Here's a rundown of who is who:

Yondu -- Michael Rooker

Nebula -- Karen Gillian — "I might have done something a little bit crazy," she says and pulls off a wig to reveal her shaved head.

Korath the Pursuer -- Djimon Hounsou

Ronan the Accuser — Lee Pace

The Collector — Benicio del Toro

Drax the Destroyer-- Dave Batista, "When I got the job, I broke down and cried like a little baby," the physically massive pro wrestler said. "I'm 44 years old, I'm the baby on the set in terms of acting experience. I go to work every day and try to learn something new."

Gamora — Zoe Saldana, "I've done blue, I figured why not try green?"

Star-Lord — Chris Pratt, on his new ripped physique: "I had a tapeworm."

Finally ... The big finish:

Joss Whedon arrives to reveal that "The Avengers 2" will be called ...

Age of Ultron!

Crowd. Melts. Down.
