Part 2 of our yearly crossover is where the action begins! Part 1 (Supergirl) was a nice setup, but there wasn’t a lot of meat to the episode to get you excited except maybe that opening and the dinner party interactions (very reminiscent of Avengers: Age of Ultron party).
Part 2 is where our heroes find out who they are up against in a hilarious scene where Barry & Kara arrive in super speed at a tech company and Oliver shows up moments later on his bike, grumpy. Our Earth-x villains are Oliver’s doppelgänger (who is apparently the Fuhrer of the Nazi regime), Over-girl (Kara’s doppelgänger and General of the Nazi army) and Eobard Thawne, yes, one and the same. He’s back, folks but more on that later. Their plan: to first steal a prism thing that gives off the power of the red sun.
