The world's most powerful band of superheroes is getting back together! Marvel's classic favorites are shown reuniting in a new trailer for the upcoming Avengers sequel, Avengers: Age of Ultron.

The early peek at the second installment debuted on Monday, Jan. 12, airing on ESPN during the inaugural College Football National Championship. In a commercial break from Ohio State's battle against Oregon, the Avengers were shown taking on their new enemy.

The latest preview for Avengers: Age of Ultron opens with shots of chaos and civilian strife as the voice of a hero is heard saying, "This vulnerable world... needs something more powerful than any of us."

Appearances are then made by original Avengers stars Chris Hemsworth, Robert Downey Jr., Jeremy Renner, Samuel L. Jackson, and Scarlett Johansson, as characters Thor, Iron Man, Hawkeye, Nick Fury, and Black Widow, respectively. 

Iron Man's human incarnation Tony Stark is shown causing trouble as he attempts to save the world. He reboots an old robotic system called Ultron as a voice is heard warning "Everyone creates the thing they dread."

Intended to keep the people safe, the robot Ultron has inconceivable powers and free will as he comes to the conclusion that humans are the real problem and must be destroyed. Voiced by James Spader, Ultron is shown wreaking havoc before he promises the Avengers, "I'm going to tear you apart... from the inside."

Due out on May 1, Avengers: Age of Ultron also stars Mark Ruffalo, Don Cheadle, Hayley Atwell, Aaron Taylor-Johnson, and Idris Elba, among others. Catch the latest look at the action flick in the video above!
