Spoilers ahead for the first two episodes of “Crisis On Earth-X.”
In last year’s “Arrowverse” crossover, Oliver Queen met Kara Danvers for the first time, and Oliver gave Kara the cold shoulder. However, she later saved his life while they were battling the Dominators, and that seemed to melt his icy heart.
Oliver and Kara are on good terms now, but their Earth-X counterparts have a completely different relationship.
In the first night of the crossover it was explained that Oliver Queen and Kara Danvers of Earth-X are husband and wife.
Stephen Amell recently teased that Kara and Oliver would share a passionate kiss in “Crisis On Earth-X” and they did, only it was their Earth-X counterparts.
In hour two of the crossover, Dark Flash, Dark Arrow and Overgirl stole a prism, and it was later explained that they want to use the prism to weaken Supergirl.
After Oliver of Earth-X rounded up all the heroes and put a device on their necks that rendered them powerless, he explained why the invasion is taking place.
Taking over Earth-1 was just one of their goals, but the other goal had to do with saving Overgirl.
It was revealed that Overgirl is dying from too much radiation in her blood, and they want to cut Supergirl’s heart out and transfer it to Overgirl so she can have clean blood and become strong again.
They tried to convince Supergirl to give herself up willingly, but when she didn’t Oliver, Barry, Sara, Stein, Jax and Alex were all imprisoned in a concentration camp on Earth-X as the second hour came to a close.
