One of the great things about having multiple television properties that all take place in the same universe is the ability to have epic crossover episodes. The Arrowverse seems to have this down to a science, and the addition of Supergirl has only made these more entertaining.
In what seems to have become an annual tradition, this year’s crossover event, Crisis on Earth-X, features the superheroes of Arrow, The Flash, Supergirl, and DC’s Legends of Tomorrow attending the wedding of Barry Allen and Iris West, only to see it interrupted by evil Nazi doppelgangers of themselves from Earth-X. And in what also seems to be tradition, images have hit the Internet before the event featuring Overgirl who appears to be Supergirl’s Arrowverse Earth-X doppelganger.
Originally introduced in DC’s Final Crisis #2 back in 2008, Overgirl was a doppelganger of Power Girl, not Supergirl. She was created using genetic material from Overman, a darker version of Superman from a world in which the infant Kal-El rocketed from Krypton in 1938 and lands in Nazi Germany. On this Earth, the Nazis would go on to win World War II and eventually control the world.
The four-part crossover event, Crisis on Earth-X, will air on The CW beginning Monday, Nov. 27 with Supergirl and Arrow, and conclude on Tuesday, Nov. 28 with The Flash and DC’s Legends of Tomorrow.
