'Heroes' unite, as the world faces 'darker' challenges in 'Justice League' trailer

DC fans, Rejoice! The 'League' has united to fight evil in the final trailer of 'Justice League'.

The makers unveiled the final trailer on YouTube and it is surely going to make fans even more excited.

The trailer starts with a grieving Lois Lane, dreaming of getting engaged to Clark Kent. But she wakes up to a completely different reality - an empty bed.

The footage moves forward with TV reports of a world falling apart, thanks to war and terrorism.

The clip also shows flashes of battle scenes between the warriors of Themyscira and Parademons, with Steppenwolf being the leader of Parademon army.

Before we hear Bruce Wayne aka Batman (Ben Affleck) telling Diana Prince aka Wonder Woman (Gal Gadot) he's been dreaming of a dark future for the world.

Bruce Wayne also describes a dream he had as "the end of the world." When Wonder Woman suggests it is an invasion, he replies, "I think it's something more, something darker."

The footage moves forward with Bruce telling all the assembled heroes, "Divided, we are not enough. The world needs Superman, and I made him a promise, which is why I've brought you together."

The trailer gives what fans have been waiting for since the first trailer - a look (kind of) on the 'Superman', but not in his cape, only in a dream seen by Amy Adams.

David Bowie's 'Heroes' replaces the initial look's take on The Beatles' 'Come Together' and no song could have been better for this trailer as it sets the tempo for what we can expect.

Helmed by Zack Snyder/Joss Whedon, 'Justice League' brings together the DC heroes Batman (Ben Affleck), Wonder Woman (Gal Gadot), The Flash (Ezra Miller), Aquaman (Jason Momoa), Cyborg (Ray Fisher), Henry Cavill (Superman), Amber Heard (Mera) and Amy Adams (Lois Lane).

The flick is scheduled to release on November 17.
