It would seem that the ambitious plans of the unification of the different comic book universes dubbed as the "Arrow-verse" is going to get a little bit bigger. With the list including comic book to television shows such as "Arrow," "Supergirl," "Legends of Tomorrow," and "Flash," plus another character from "Arrow" will be making it to the party, namely Prometheus.
According to Movie Pilot, the "Arrow-verse" will be crossing over once again to face the doppelgangers from an alternate dimension of Earth called Earth-X. In this alternate reality, the Nazis win the Second World War, which in effect spawns the evil versions of the characters as we know them. This means that the heroes in their respective shows will be going up against their alternate selves, as well as the villains from Earth-X.
Prometheus will not be joining the main heroes, but will appear as Prometheus-X. According to Entertainment Weekly, they speculate that Quentin Lance, played by Paul Blackthorne will be donning the mask of Prometheus-X. This is due to the fact that in season 5, it had been previously teased that it is possible for Quentin to eventually take the role of Prometheus, which seems to be very likely for the "Arrow-verse" crossover.
However, in a tweet by Colton Hayes, he teased that "Roy's coming back very soon," which makes him another eligible possible candidate for the character. According to Blasting News, the events that will spark the crossover will occur during Barry Allen and Iris West's wedding day, which is a very unfortunate thing for them. Fortunately, fans should be excited, because Stephen Amell, who plays Oliver Queen, promised that the crossover will be exciting.
The CW has been very discreet about the details regarding the storyline of the "Arrow-verse" crossover, but it will be shown in two consecutive nights on Monday, Nov. 27, and Tuesday, Nov. 28.
