Marvel has the edge over its rival DC at the cinema, but DC’s TV properties – Supergirl, The Flash, Arrow and Legends of Tomorrow – are strong. Starting today (November 28), a series of four crossover episodes called ‘Heroes Vs Aliens’ looks to be the DC TV equivalent of Marvel’s Avengers Assemble, bringing some of the most beloved superhero properties together onscreen for the first time ever. The latest trailer, below, sees characters from the four series in an epic crossover extravaganza. Here’s what we’re most excited to see.

Supergirl | Heroes v Aliens: The Dominators | The CW

The Dominators are coming…can DC’s heroes team up to stop them? The invasion begins Monday at 8/7c on The CW! SUBSCRIBE: //bit.ly/TheCWSubscribe About Supergirl: SUPERGIRL is based on the DC character Kara Zor-El, Superman’s cousin, who after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be.

1. Epic fighting team-ups

With over 11 superheroes coming together across the four episodes, it only seems only right that there’ll be some awesome team-ups between them. Supergirl and the Flash already met during Flash’s visit to the alternate Earth (it’s a long story) and this new trailer shows the pair high-fiving as they take on an unknown baddie.

2. The Return of Deathstroke

While the crossover event is massive in itself, Tuesday night (November 29) sees Arrow take the reins, which just happens to coincide with its 100th episode. Celebrating this momentous occasion we see a brief glimpse of season two’s antagonist, Deathstroke. Manu Bennett’s portrayal of the assassin proved to be a huge hit with the fans and his appearance can only mean one thing – one epic fight scene is coming.

3. The Dominators being pure evil

It takes a pretty huge threat to bring this many characters together. Enter The Dominators: aside from sounding like an up-and-coming rock band, the alien race are hell-bent on invading earth and harvesting those with superpowers. They look to be lifted directly from their comic-book pages from 1989’s three-issue run ‘Invasion!’, and they seem pretty threatening in the trailer. As Wally West says, “That is not the name of a species that comes in peace”.

4. The Flash saying goodbye

“It’s been an honour to know all of you, to fight alongside you, now it’s up to you to keep our home safe.” The fastest man alive, who can create tornados with his hands, run across water, and come out on top in a battle with a gigantic Gorilla, is about as heroic as it comes. With the Flash uttering the above line, is he saying goodbye?

 

5. Even more superheroes!

As is probably obvious by now, there are going to be a lot of people saving the day here. Thing is, there could be so many more. Arrow has a team of new recruits, the Legends have met multiple heroes throughout time, The Flash has two sidekicks and Supergirl has even introduced big hitters such as Martian Manhunter and Superman. Although it’s pretty much a safe bet that Supes won’t be making an appearance, the potential for more heroes is almost endless. If there isn’t a scene with everyone walking away from an explosion in slow motion, a huge opportunity gonna be wasted.

The crossover event begins with Supergirl on the Monday (November 28) then continues with Arrow (November 29) The Flash (November 30) and finishes with Legends Of Tomorrow (December 1), all on The CW.
