Update (March 20th, 2024)
At this new time of writing (March 20th, 2024), the Lego DC Super Heroes line has not had a non-Batman set available for DC since the end of 2021 (being 76157: Wonder Woman vs. Cheetah). Through both 2022 and 2023, the DC theme has averaged only 7 sets each year. And in that time, many iconic and inspiring characters such as Wonder Woman and Superman have been absent from Lego's DC offering. Furthermore, many other superheroes such as The Flash, Green Lantern, Aquaman, Shazam, and thousands of other characters are at the ready to spark kid's imaginations and drive them to aspire for more.
Some of the movies that have come out since 2021 include Black Adam, Aquaman and the Lost Kingdom, Blue Beetle, The Flash, and Shazam! Fury of the Gods. With all these film releases and opportunities to create Lego products, not a single Lego set has been released for any of these movies. With James Gunn's planned revival of the DC movie universe starting with Superman in 2025, there is hope for a revival of DC Lego sets. But seeing all the recent movies that have not been used as inspiration for Lego sets makes me and many other fans worried about the future of the DC theme.
Other small but great kids shows that are currently airing such as Batwheels, My Adventures with Superman, and Teen Titans Go! have not had Lego sets made for their respective shows.
I'll also point out that many of the locations and characters used in the description of the DC Theme on Lego.com are not currently referenced in Lego form whatsoever.
In solving this problem, there are many solutions that would be profitable for Lego, DC Comics, and Warner Brothers as well as DC fans alike.
One solution would simply to make sets of large, iconic locations. A comparable location that Marvel has (76269: Avengers Tower) is a large and popular set that has done very well. Locations in the DC universe such as the Hall of Justice or the Daily Planet could have the same potential to reach a wide market.
Another solution could be to take a different route from Marvel by being more focused on comic book scenes: taking epic moments from comic book history and recreating them in Lego form. This could not only be included with an excerpt of a comic book, either digitally or physically, to showcase the context of the scene, but it would also connect young Lego fans to become new comic book readers and familiarize them with various characters throughout comic book history. Another outcome of this approach is that it encourages young people to be more interested in reading.
When I think of DC and its comic book history, it means more to me than just a fun or interesting story. DC showcases the best ideals in people we can aspire to be. It inspires us to overcome and persevere through our challenges in the real world. What could be a better opportunity than to connect young builders to reading and inspiration? If you feel as strongly about this as I do, then please sign the petition and let the people at Lego, DC, and Warner Brothers know how strongly we feel about this. And if you know anyone that works at any of these companies, please do your best to share this sentiment with them.
