Multiverse

the gravity falls fandom is starting to scare me again.

Note: This discussion is about sitcoms. If you have no interest in them, then you may not care about this.

We all know how Nickelodeon is making a SpongeBob multiverse by making several spin-offs such as Kamp Koral and The Patrick Star Show, and movies like Saving Bikini Bottom and Plankton. But with the premiere of When Worlds Collide next week, Danger Force, Side Hustle, That Girl Lay Lay, Young Dylan, and Warped! will crossover putting them all in the same universe. Danger Force is a spin-off/sequel of Henry Danger which has had many crossovers. It has previously crossovered with The Thundermans, Game Shakers, and Knight Squad. The Thundermans also had a crossover with The Haunted Hathaways making that an extension.

So now the following sitcoms take place in the same universe:

Henry Danger/Danger Force

The Thundermans

The Haunted Hathaways

Game Shakers

Knight Squad

Side Hustle

Warped!

That Girl Lay Lay

Tyler Perry's Young Dylan

It may go even further than that though:

Henry Danger has a character named Goomer who is the assistant of Frankini (a villain who is also the main antagonist of When Worlds Collide). Goomer previously appeared on Sam & Cat as Dice's wrestler and a friend of Sam and Cat. He mentions in his Henry Danger debut that he previously hanged with Frankini's sister (Frankini is played by Frankie Grande, Ariana Grande's brother), which means he is either referring to Cat Valentine or Ariana Grande. Frankini seems crazy enough to be Cat Valentine's mentally insane brother that she always mentioned but never appeared. That means Henry Danger MIGHT take place in the same universe as Sam & Cat, which would mean it takes place in the same universe as iCarly and Victorious. Although, there is some counterevidence to this theory, such as Nathan Kress appearing in an early Henry Danger episode, Ariana Grande being mentioned in Henry Danger: The Musical!, and iCarly being a TV Show on Game Shakers, but continuity errors happen all the time, and it might be possible for Ariana Grande and Cat Valentine and Nathan Kress and Freddie Benson to exist in the same universe. So if Henry Danger and Sam & Cat took place in the same universe, than you have the following sitcoms in one universe:

Henry Danger/Danger Force

The Thundermans

The Haunted Hathaways

Game Shakers

Knight Squad

Side Hustle

Warped!

That Girl Lay Lay

Tyler Perry's Young Dylan

Sam & Cat

iCarly

Victorious

That's a whopping 12 series all in one universe, similar to the Marvel Cinematic Universe.

Some notes: Drake & Josh is a TV show in iCarly, Victorious, and I believe Henry Danger, so it doesn't take place in the same universe.

Nicky, Ricky, Dicky, and Dawn doesn't take place in the same universe as they refer to The Thundermans as a tv show.

In Henry Danger's animated series "The Adventures of Kid Danger", Game Shakers is considered a TV Show, meaning TAoKD is in a separate universe.

Bonus: If you count Portal Chase, Henry Danger was seen with SpongeBob SquarePants, The Loud House, and more. Of course, this isn't canon.

P.S: Sorry if this was cringe, I warned you it would be about sitcoms.
