Arrowverse Four-Night Crossover Gets a New Teaser Plus New Posters

The CW is about to make history with its epic four-night mega crossover event titled “Heroes Vs Aliens”. The crossover will see the heroes of Arrow, The Flash, Supergirl, and Legends of Tomorrow all come together to take on the evil alien invaders, The Dominators. The Dominators are an Alien race interested in harnessing the metagene (the gene that gives metahumans their powers) to enhance members of their own species.

Ahead of the crossover event, The CW has released a new found footage teaser that suggests this isn’t the first time the evil aliens have made their way to Earth. Could the time traveling heroes of Legends be taking the heroes of Arrow, The Flash, and Supergirl back in time to prevent the alien threat from invading in the future??

Four new posters have also hit the web. The posters are rather serviceable as they feel a bit rushed in design and don’t feature the best photoshop, most notably the poster for Arrow.

The four-night crossover event begins at the end of Supergirl on Monday, November 28th, and will then carry over to The Flash on Tuesday, Arrow on Wednesday, and conclude on Legends of Tomorrow that Thursday night.

The crossover episode of Arrow also happens to be the series’ 100th episode and will see the return of many cast members including Katie CassidyJohn BarrowmanNeal Mcdonough, and Susanna Thompson.

Supergirl airs Mondays at 8 p.m. ET/PT, The Flash airs Tuesdays at 8 p.m. ET/PT, Arrow airs Wednesdays at 8 p.m., and DC’s Legends of Tomorrow airs Thursdays at 8 p.m. ET/PT on The CW.
