Move over, James Gunn: Stuart Fails to Save the Universe will have DC crossover episode — and there's one iconic superhero HBO Max would be stupid not to include

I can't say that I've been paying too much attention to what's happening at San Diego Comic Con, but I certainly didn't expect new Big Bang Theory spinoff Stuart Fails to Save the Universe and the DC universe to be mentioned in the same breath.

According to Nerdist, DC President Jim Lee made a surprise appearance at the HBO Max show's panel in Hall H, confirming that multiple DC characters will cameo later in the season.

“Some of the DC characters they have in it, I think, are some of the best versions I’ve seen of those characters,” Lee said during the panel.

In other words, watch out James Gunn. With Supergirl failing to make much impact earlier this year, maybe Stuart Fails to Save the Universe actually is the best DC Universe iteration we'll get in 2026.

If you've been watching the teaser trailers closely, you might have seen underrated characters such as Gotham villain Mr. Freeze have already featured. But if creators really want to bring the existing Big Bang Theory lore full circle, the show can't omit the superhero that's been staring us in the face for years.

Stuart Fails to Save the Universe's DC crossover need to include The Flash to commemorate — or spite — Sheldon

Even if you've only watched one episode of Big Bang Theory in your lifetime, my campaign for The Flash to join the Stuart Fails to Save the Universe x DC episode hopefully won't come as a surprise.

He's Sheldon's (Jim Parsons) favorite DC superhero, and the reason why, nearly every time we see him, he's sporting the iconic T-shirt with the Flash logo.

We're going to be on tenterhooks for all of the new show's 10-episode run to see if Sheldon makes a cameo appearance, and dropping in The Flash as a potential clue could be a really fun way for the creators to mess with us.

On the flip side, a Flash cameo could also work to either spite or celebrate Sheldon. The reason why Stuart (Kevin Sussman) is in this multiverse mess in the first place is because he broke a device built by Sheldon and Leonard (Johnny Galecki); bringing his favorite superhero closer to home could be a great way to apologize.

However, this is a multiverse show, so The Flash likely won't be appearing in the Sheldon we know's reality. So if another Sheldon met the Flash instead... our one would be furious. That, in itself, is hilarious.

At this point, I'm purely speculating. We've got no idea which DC characters will appear in Stuart Fails to Save the Universe, nor do we know exactly which episode they will be in. Regardless, we can definitely assume that the crossover will be an epic one.
