The Earth-X Versions of Arrowverse Characters Introduced in "Crisis on Earth-X"

Guardian

Earth-X's version of Guardian/James Olsen is a character we meet right at the start of "Crisis on Earth-X", and, unfortunately, that appearance sets the tone for everything we later learn about the Nazi dystopian world. Guardian-X stands up to Dark Arrow in hand-to-hand combat with Guardian's shield bearing the American flag. Unfortunately, Dark Arrow does get the better of Guardian and comments that the flag on his shield is not only meaningless but a bullseye. Dark Arrow then shoots Guardian-X in the chest with an arrow, with Guardian-X dying for the cause.

While Guardian dies early on, his defiance in the face of Dark Arrow -- who turns out to be the Fuhrer of Earth-X -- is a hint at other heroes we will meet later on in the crossover: members of the Freedom Fighters resistance.

Overgirl

There are 53 Earth's in the multiverse and there are 53 Karas. The Earth-X version of Supergirl may be Kryptonian, but she's not a hero. The Earth-X Kara goes under the codename Overgirl, and instead of being there to help humanity, she's there to rule over it with an iron fist. Married to Dark Arrow, she appears to be second-in-command of the Nazi forces but equally as brutal as her husband.

That brutality shows itself very clearly when the Earth-X invaders plans are revealed. Overgirl is dying due to getting too much solar radiation and needs Kara's healthy heart in order to survive. That's right; the Nazi's invaded in order to kill Kara and take her heart. Fortunately for Kara, they don't succeed, and Overgirl dies.

Dark Arrow

The Fuhrer of Earth-X, Dark Arrow is the doppelganger of Oliver Queen. He brutally kills Guardian in the opening moments of "Crisis on Earth-X", but proves himself to also have emotions under this Nazi exterior. When Prometheus-X/Tommy Merlyn kills himself while in custody of the heroes, his sadness over the death leads Reverse Flash/Eobard Thawne (who, by the way, is not from Earth-X and is instead the same Thawne The Flash has been battling for years) to question if Dark Arrow can put aside his feelings for the task at hand.

Of course, Thawne has his own motivations, and while conquering Earth-1 for the Nazi banner is on Dark Arrow's to-do list, his bigger plan is to get a new heart for his dying wife, Overgirl.

Alex Danvers

Not seen in the crossover, Earth-X's Alex Danvers is mentioned by Overgirl. While Alex Danvers has repeatedly shown on Supergirl that she will do anything to protect her sister, Kara, it doesn't sound like that was quite the case on Earth-X. Overgirl reveals that her version of Alex wasn't the protective type. Earth-X Alex tried to kill Overgirl. The fact that we don't see Earth-X Alex strongly hints that Overgirl turned the tables and killed her instead.

Quentin Lance

Earth-X has it's own version of Quentin Lance, and like most of the Earth-X characters we meet, this Lance is a Nazi. We're introduced to him when he rounds the heroes up in the Earth-X concentration camp and then takes him out to execute them by firing squad. This Lance is a brutal man, far different than the loving if troubled father we've seen on Arrow. Nazi Lance reveals that he also had a Sara for a daughter, but alludes that he had her killed or killed her himself because she was bisexual. He also later brings out a woman for Oliver (who is posing as Dark Arrow) to kill as a test of identity.

Sara Lance

Another character mentioned but not seen, Nazi Quentin Lance reveals that he had a daughter who looked exactly like Sara (Caity Lotz), but she, like Sara, was also bisexual. That simply wouldn't do, and Nazi Lance revealed that she was removed from his lineage. We take that to mean he either killed her himself or had her killed as her sexual orientation didn't align with the Aryan ideal despite her blond hair and blue eyes.

Citizen Cold

"Crisis on Earth-X" saw the return of Wentworth Miller to the Arrowverse, but not as Captain Cold. The crossover introduced his heroic Earth-X counterpart, Citizen Cold. Citizen Cold may have all of Captain Cold's wisecracking and bad jokes, but he's very different from his Earth-1 counterpart. He's law-abiding (other than the whole being a Freedom Fighter bit,) always has a very detailed plan, and is in a loving relationship. It's revealed in the crossover that Citizen Cold is in a relationship with The Ray.

Winn Schott

Winn Schott (Jeremy Jordan) may be Kara's best friend and one of the smartest people on the DEO, but on Earth-X he's a general in the forces of the Freedom Fighters. Earth-X Winn doesn't have any of the silly, upbeat personality we've come to love from Kara's Winn. Instead, Earth-X Winn is sharp, focused, and determined to take full advantage of the Fuhrer and Overgirl being on Earth-1 to shut down the portal and use the opportunity to save his world. We can't help but wonder if part of what's contributed to this harsh version of Winn is all the loss experienced on Earth-X, potentially including that of Guardian.

Felicity Smoak

Remember how we said Earth-X Quentin Lance was brutal? Earth-X Felicity is the woman he brought out to see if Oliver was the Fuhrer or not. On Earth-X, Felicity is a prisoner in a concentration camp, and Lance wants Oliver to kill her for the infraction of giving her food ration to the starving children in the work camp. Oliver is unable to kill her, which leads to Oliver revealing himself, but we're left with some hope for Earth-X Felicity. Oliver gives her a gun, presumably providing her the means to help liberate herself and others.

Mick Rory

Perhaps the most humorous Earth-X counterpart reveal is that of Mick Rory. Earth-1 Mick is notorious for his dislike of cops, which is why when Citizen Cold reveals that the Earth-X Mick was not only a good man, but that he died rescuing police officers from a burning police station it was not only a much appreciated moment of levity in "Crisis on Earth-X" but a shock for Mick, who declared he felt sick at realizing that there was a version of him who actually saved cops.
