The Flash, a beloved hero of the Arrowverse, has crossed paths with Supergirl on multiple occasions. His first appearance, and perhaps most memorable, was in Season 1, Episode 18, titled “Worlds Finest.”
The Flash’s Debut in National City: A Cinematic Collision
The arrival of Barry Allen, aka The Flash, in National City marked a significant moment for both series. Before this crossover, Supergirl existed in a separate continuity from the established Arrowverse (which included Arrow, The Flash, and Legends of Tomorrow). “Worlds Finest” cleverly bridged this divide, opening the door for future crossovers and solidifying Supergirl’s place within the wider superhero universe.
The episode masterfully balances the established tones of both shows. Supergirl’s generally brighter, more optimistic outlook contrasts with the often darker and more serious themes explored in The Flash. This contrast creates a dynamic and engaging narrative, as both heroes learn from each other and work together to overcome a common threat.
The plot revolves around Barry accidentally breaching the multiverse after exceeding his speed capabilities. He finds himself in a parallel reality, Supergirl’s universe, and immediately joins forces with her to combat Livewire and Silver Banshee, two of National City’s most formidable villains. The episode is filled with exciting action sequences, lighthearted banter, and a genuine sense of camaraderie between Supergirl and The Flash.
The Significance of “Worlds Finest” for the Arrowverse
“Worlds Finest” wasn’t just a fun crossover; it was a crucial stepping stone for the entire Arrowverse. It proved that these shows could successfully interact and share characters, leading to the annual multi-episode crossovers that became a staple of the CW superhero programming.
The success of this initial crossover demonstrated audience appetite for these large-scale events, prompting the networks and showrunners to invest further in creating interconnected storylines and expanding the shared universe. From that point forward, characters from Supergirl would frequently appear in other Arrowverse shows, and vice versa.
Furthermore, the episode established the concept of the multiverse within the Arrowverse in a more concrete way. While the idea had been hinted at previously, “Worlds Finest” explicitly confirmed the existence of multiple Earths, each with its own unique version of reality and its own heroes and villains. This opened up countless storytelling possibilities and allowed for the introduction of characters and storylines that would otherwise be impossible.
Beyond “Worlds Finest”: Subsequent Flash Appearances
While “Worlds Finest” is the definitive answer to where The Flash first appeared on Supergirl, it’s important to acknowledge he wasn’t a one-time visitor. Barry Allen continued to be a key figure in subsequent Supergirl seasons, often participating in larger Arrowverse crossovers.
These crossovers usually involved a significant threat requiring the combined efforts of all the Arrowverse heroes. Events like “Invasion!,” “Crisis on Earth-X,” and “Crisis on Infinite Earths” saw Supergirl and The Flash fighting alongside Arrow, the Legends of Tomorrow, and Batwoman to save the multiverse.
These later appearances, while less focused specifically on the Supergirl series, were nonetheless crucial to the overarching narrative of the Arrowverse and showcased the strong bond between Supergirl and The Flash. They demonstrated the power of teamwork and the importance of unity in the face of overwhelming adversity.
