A new and final teaser for "Avengers: Age of Ultron" has been released, and it shows every superhero in the league and even their opponents with their own sharp one-liner moments and cool fighting moves. The team is shown suiting up as they battle Ultron and every creature on his side.

The trailer, as opposed to the previous ones that focus mainly on the darkness of the crisis at hand, is on the jocular side of things. There are even glimpses of Quicksilver and Scarlet Witch in the trailer, but the spotlight is pointed at Black Widow and how accomplished her friendship and team-up with Captain America is.

Fans already saw it bloom in "Captain America: Winter Soldier," with Black Widow finding a way to get the mighty soldier a proper date. It seems that "Avengers: Age of Ultron" will again be witness to their growing friendship.

At the end of the trailer, the femme fatale helps the Cap battle with the rampaging sinister mechanoid as she delivers his shield to him in time before Ultron breaks his neck. Before she gets there, she looks ultra cool as she drives her motorcycle under a huge truck in slow motion. 

In the past, Scarlett Johansson, who plays Black Widow, has hinted that "Avengers: Age of Ultron" will hark back to her dark and painful past. Clearly, there is more to the fierce agent than drawing weapons and saving people.

"Avengers: Age of Ultron" will see Iron Man (Robert Downey Jr.), the Hulk (Mark Ruffalo), Thor (Chris Hemsworth), Captain America (Chris Evans), Black Widow, and Hawkeye (Jeremy Renner) as they put a stop to Tony Stark's very own creation, intended for peacekeeping but going all evil and running amok. 

"Avengers: Age of Ultron" premieres on May 1. For the time being, fans can enjoy the film's final trailer.
