Could be from a show and/or movie.
The Cartoon Network City bumpers. Really cool to see all the cartoon characters you love being able to interact with each other in a big city, even if for just a few seconds at a time.
Though, if we’re talking actually part of a show and/or movie, I actually cannot think of anything besides maybe the Cartoon Network cheese aliens one, which I don’t even know if you could consider a crossover.
It’s headcanon, but in my mind Terminator and the Matrix are in the same universe. Terminator is how things started, the Matrix is how it ends.
So the Animatrix is just propaganda?
In my head Mad Max and Judge Dredd live in the same universe.
I’d watch that.
Bubba Ho-Tep and Army of Darkness
Army of Darkness basically meets the horror icons in the Vs series
Terminator versus Robocop
Doctor Who and Star Trek
X-Files / Simpsons
Scooby-Doo and Johnny Bravo.
That might open up Johnny Bravo being in the same universe as a bunch of stuff, didn’t Scooby-Doo do a ton of crossovers/cameos?
I’d have to go with Bladerunner, Firefly/Serenity, Alien, and Predator (they all have the Weyland-Yutani corporation and some have crossovers). Wouldn’t mind seeing a nicely done mash-up show or movie of that (but it would probably end up being a mediocre action sci-fi).
A Mashup of basically every sci-fi/Fantasy story that is set on Earth and is not irreconcilably different. Marvel/DC/Dresden Files/Harry Potter/Percy Jackson/etc.
John Munch/Munchiverse/Tommy Westphall Universe
It’s easier to link to all of the shows:

And a good description:

The thing is it’s all clever inside baseball references, not intentional.
It sort of detracts from the magic to rationally think about Friends, X-Files, Seinfeld, and Buffy all being in a shared universe. Vampires LOVE New York.
I realized this when watching Homicide: Life on the Street, but I didn’t realize the list was so extensive!
The Critical Role episodes that carried over into official DnD lore.
Tap for spoiler
Arkhan the Cruel, played by Joe Manganiello, helped the party defeat Vecna and while they were celebrating he stole Vecna’s Hand. That is why in (I think) Descent to Avernus he now officially has the hand while residing in Avernus. I guess he still has it while Baldur’s Gate 3 runs.
phineas and ferb’s powers included combining the tri-state area with star wars and marvel.
The fediverse.
