If I could direct a wreck it ralph 3 , here's what i came up with.  If the first movie is about video games and the second movie is about the internet,  then I'd make the third movie about television 

The title of the film is Ralph wrecks the Broadcast. 

So litwacks arcade has gotten more popular and he has expanded , now making it bigger to host birthday parties and stuff. He has a bunch of TVs installed into the arcade , which ofc the video game characters can go into to explore.  Unlike the second film , I want ralph and Felix to be the main stars but Vanellope and Calhoun will also be there , as big supporting roles. They go inside the tv and meet a bunch of television characters,  all with different art styles to match their show whether it's 2d animated , puppets , live action,  anime , etc. The way it works is whenever a new show is made , the characters are then essentially created and spawn into the tv world,  and are forbidden from leaving their show to explore,  unlike the game characters who can leave their games. The tv characters follow a script for each new episode and act them out in real time , thus creating a episode.  

Ralph and Felix then discover a shocking truth : Fix it Felix jr has a cartoon show. Their show is very similar to the mario bros and Zelda cartoons from the 90s. Tv Felix is a cocky yet stotic hero , one of the nicelanders is a nice secretary lady who Tv Felix has a crush on and Gene in the show is a mayor.  Tv Ralph is a pure arrogant villain who's plan is to steal felix's magic hammer and rebuild the world into what he wants. He's paired up with a comedic relief sidekick named Stacks , because every villain in a 90s cartoon needed a bumbling lackey to kick around. This is when the two ralphs and felix's meet and discover about each other's worlds and when the conflict begins

So tv ralph is the main antagonist and he pretty much becomes self aware. He discovers upon being a tv show character that he is always destined to lose and because of his script , he will never be able to defeat tv Felix and rule the world , because the show makes it so that Felix triumphs over him all the time. He then gets increasingly upset to discover that because of how their game works,  that if a player messes up then game Felix can lose against ralph. Having an existential crisis about his existence,  tv ralph then decides to change EVERYTHING.  He successfully steals both the hammers of both felix's and with their overpowered properties , is allowed to leave out of his show and starts changing other tv shows , even making his way to the arcade and changing video games in his image. He also ditches stacks and kicks him aside. Game ralph and felix , and tv show Felix then chase after him to stop his rampage.  

As for Vanellope and Calhoun,  this is where I have them doing something major because they discover themselves that they also have their own tv shows : Hero's duty being the neon genesis type anime while sugar rush is a Dora the explorer / my little pony type kids educational cartoon.  While game Calhoun likes the look of her show , game Vanellope doesnt vibe with her show counterpart,  who fully embraces being a sweet and kind princess rather than being a adventurous tomboy. Thanks to tv show ralph however,  they're all allowed to leave their shows and start crossing over with each other , creating chaos. 

Eventually,  everyone ( Tv show Felix,  game Felix and game ralph , both Vanellopes and both Calhouns and Stacks ) corner tv show ralph. Tv Ralph tries to get game ralph to join sides with him , reminding him that he's the bad guy of the game and that he must be hated and has nobody but together they can rule over the arcade and the television world. Game ralph refuses  But thanks to Stacks,  they successfully stop tv show ralph before he uses the hammers to change the game and tv worlds inside that room that king camdy used to alter everyone's memories in thw first movie. Also during the fight , which features other television villains fighting against television heroes and the game characters,  Vanellope runs off to the internet world and gets some help from her friends in Slaughter Race. She then returns to the arcade with something to show tv show ralph : Fan art of his character and photos of collectable toys and merch. They explain that even though he always loses against Felix and can never win against him because of the rules of his show , that he's still an incredibly popular character who fans love and adore. 

This finally ends tv show ralphs rampage and he returns the hammers to both felix's who fix all the damage and return everyone home. Tv show ralph reunites with Stacks and realizes even if he loses in his show , that no one does it better than him and he's gonna put on one hell of a performance. 

The Movie ends with another joke like the Rick roll from the second movie,  except its a trailer for a live action wreck it ralph movie with the actors ( John C. Reilly , Sarah Silverman , Jack McBrayer and Jane Lynch ) dressed up as their characters as they reenact scenes from the first wreck it ralph movie trailer. 

My pitch for a Wreck it Ralph 3
