Arrow actor Stephen Amell has shared the first look of his evil character from the upcoming Arrowverse crossover event titled, Crisis on Earth X, on his official Twitter page and fans couldn't be happier.

The epic four-way crossover event between Arrow, The Flash, Supergirl, and Legends of Tomorrow will feature Barry and Iris' wedding being crashed by Earth X villains and will pit the heroes against their evil doppelgangers from a parallel Earth wherein the Nazis won World War II.

In the photo shared by Amell, we see Nazi Arrow in a black costume, standing with the evil Supergirl and the evil Flash, aka actor Tom Cavanagh in his iconic Reverse Flash suit. Most fans replied to him, stating that they can't wait to watch the episode, while others came up with funny captions.

A user wrote, "can't wait for this." Another hilariously commented, "An archer, a fast dude and a flying woman walk into a bar."

A user pointed out that Arrow looks better in his green suit, and noted, "Eh Green is more your colour." A fan of The CW shows said, "Definitely, this season of all the shows has been phenomenal so far and i can't wait for the crossover shows."

"Officially very more excited for the crossover than I already was (I know that sentence doesn't make any sense but neither does this shot!!)," tweeted a social media user. A big fan of Supergirl actress Mellisa Benoist replied, "Melissa looks so goooood."

Previously, Arrow executive producer Wendy Mericle spoke to The Hollywood Reporter about the upcoming crossover and teased a rather emotional episode."The biggest surprise will be the emotional component of the crossover," said EP Mericle and teased a big role for Oliver (played by Amell).

She explained, "I don't think anyone is going to see that coming. It's very much a dark love story. It's the underpinnings of that that will make the Earth-X element a real contrast to that. Oliver has a big role to play in it, and it's bigger and better than any crossover we've done in the past. It's going to be epic."

The event will kick off on Monday, 27 November with Supergirl and Arrow (on a special night for one week only), and conclude on Tuesday, 28 November with The Flash and Legends of Tomorrow episode.

The official plot synopsis reads as follows:

Barry and Iris's wedding brings the gang together, but things go awry when villains from Earth-X attack the ceremony. All of the superheroes band together with help from their super friends like Citizen Cold, The Ray, Felicity Smoak, Iris West and Alex Danvers to take on their most formidable villains yet. Earth's mightiest heroes - Green Arrow, Supergirl, The Flash and White Canary -lead their teams into battle to save the world.
