A little Crisis on Infinite Earths easter egg from way back in Arrow season 1 has been explained by Arrowverse producer Marc Guggenheim. Arrow concluded in January, bringing Oliver Queen's journey to a close. Fans are hoping the spinoff show gets picked up.

Few could have predicted how big Arrow would become. The first season began airing in 2012, and introduced audiences to the world of Stephen Amell's Oliver Queen. It was The CW's first comic book program since the conclusion of Smallville. Arrow was clearly taking cues from the Batman mythos, and continued to do so later with its Ra's al Ghul storyline. Interestingly, one of the original finale ideas was Oliver Queen's death inspiring Batman. Arrow would kick-start a shared TV universe of superheroes, from The Flash to Batwoman. Oliver died a hero's death, giving his life in the battle against the Anti-Monitor. Crisis on Infinite Earths was supremely ambitious, and actually had an easter egg all the way back in Arrow season 1.

Over on Twitter, one user asked Guggenheim about an easter Egg from the 13th episode of Arrow season 1. In it, there's a computer screen with the names "Wolfman" and "Perez." Of course, these names are referring to the creative team behind the original Crisis on Infinite Earths comic book: Marv Wolfman and George Pérez. According to Guggenheim, the team didn't know Crisis would be made all those years later, but enjoyed inputting references to DC legends.

It must be surreal to go back and see this easter egg. The crossover event was a big deal in the original comic, getting rid of the multiverse in favor of a unified primary Earth. The Arrowverse version united the worlds of The Flash, Supergirl and Black Lightning, while also establishing different worlds for Titans, Stargirl, and more. There will probably never be a TV event as grand as Crisis on Infinite Earths.

Will Oliver Queen ever appear again in the Arrowverse? Recently, Amell said he was done with the character. Although some might be disappointed, the character had a beginning, middle, and true conclusion. Going forward without Arrow, the Arrowverse will nonetheless continue with old and new characters alike. Interestingly, the next crossover event is already planned, though one shouldn't expect it to be as grand as Crisis on Infinite Earths. Those who missed Crisis, or wish to relive the action and many cameos, can check out the re-airing this coming week.
