After tonight's episode of Arrow, the next time will see the characters from the Arrowverse will be on Monday night for the start of Crisis on Earth-X when they get together for the wedding of Barry Allen (Grant Gustin) and Iris West (Candice Patton). And as we've seen in all the trailers, the wedding is interrupted by Nazis. We also know they have some meta humans and vigilantes of their own including evil versions of Supergirl, the Flash, and Green Arrow… or at least sort of. Other promo images include another dark archer, an A.T.O.M. drone, and Red Tornado. There are also some heroes from Earth-X introduced including The Ray (Russell Tovey) and Citizen Cold (Wentworth Miller).
The extended trailer below talks about them having a doomsday device and showing us Overgirl at the same time. That might be a red herring… but the other interesting thing is we get to see Green Arrow fire an arrow that then separates to reveal a glowing green head. And he's fired it at Overgirl so we can almost bet that he's made a Kryptonite arrow — which is something straight out of the Batman playbook. Make sure you can take down all of your friends if need arise. I'm sure that's going to be a conversation or two in the four hours. And the fact we're seeing it in the trailer means that it probably doesn't work they way they hope it will.
Crisis on Earth-X crossover event starts with back-to-back episodes of Supergirl and Arrow at 8 p.m. ET on Monday, November 27th and then concludes with back-to-back episodes of Flash and Legends of Tomorrow at 8 p.m. ET on Tuesday, November 28th on the CW.
