Live Poll: Favorite Arrowverse Crossover

@Pencho15, I thought it could be a bit clearer, so I tweaked the order and added a few details. Feel free to use it or not, or to pare it for length or edit it otherwise to your liking.

I also don't think the Arrowverse is going away and will continue to be popular in reruns. I just think it has temporarily or permanenty ceased to expand with no currently running series.

"On August 1, 2022, it was announced that The Flash would be concluding with its upcoming ninth season, which would also act as the conclusion of the Arrowverse, due to Superman & Lois having been confirmed to take place in an adjacent universe. In May 2023, The CW stated that it had passed on Justice U." (From Wikipedia)

After eleven years, the Arrowverse is coming to an end with the final episode of its last remaining member series, The Flash (2014), airing on May 24, 2023. Over the past decade, the DC Arrowverse has been by far the dominant comic book superhero media franchise on television.

The Arrowverse includes six CW TV series and two CW Seed webseries, all of which are set in a shared universe with interconnected settings and common plot elements. Its television series include Arrow, The Flash, Supergirl, Legends of Tomorrow, Black Lightning, Batwoman, and web series featuring Vixen and Freedom Fighters: The Ray.

While most series characters have their own stories to tell on their respective TV series, part of the appeal of the Arrowverse is that each season fans could expect a crossover episode featuring many of their characters in a single, combined storyline.

Now that we no longer look forward to new Arrowverse episodes, which of their signature crossover events was your favorite one?
