I'm cutting the original storyline of Five Nights at Freddy's off at the third game and removing Afton's weird implied Pamela-Voorhees-meets-Gendo-Ikari motivation for his murders; he kills for a feeling of power and punishment. As much as I like the sci-fi elements, they utterly ruin his character. I'd also remove 3's cutscene of him coming back: he's dead, and he stays dead.

However, I do believe there would be room for sequels after that. I think it could be neat to have games skipping straight to the Vanny story and making her an actual developed villain as well as a real copycat killer, perhaps even starting a small cult of sorts around the Fazbear brand and Afton's legacy.

The Wheel of Time show.... Change it to be like the books. I felt like the books read well and could have been adapted without changing much. Keep to the source material and embellish areas that weren't as well discussed like east of the waste, the islands to the west, etc.

I'm deleting Homeworld 2 from existence.

More The Expanse. More Chrisjen Avasarala. More!

at least half of Dragon Ball Super

Star Trek.

Everything after Voyager gets axed completely. 100% retconned. Doesn't exist. You can't even joke about happenings in it in any new works.

Voyager and DS9 themselves get trimmed down. DS9 loses 75% of its episodes, Dominion war erased, mundane space station stuff instead, no religious weirdness validated. Voyager gets better ending but retains most of its episodes.

ToS gets turned into legendary chronicles rather than full canon with the more absurd less science bits cut out or reduced to the fantasies of the chronicler. Main stories and characters retained with >=80% of it surviving. Movies from both ToS and TNG era retain full canon status.

It is established that alternative dimensions are extremely limited in number, you cannot do Marvel universe #69 stuff with it, the main one is the nega-universe with evil everything and a few other isolated pocket universes that are short-lived and unstable (often as a result of warp core implosion weirdness and such).

All existing writers and producers currently associated or associated since the end of the Voyager era are summarily fired with prejudice. New ones are hired and quizzed by me to ensure at least the main producers are communists like Roddenberry and do not want to turn my hopeful FALGSC property into grim-dark in space IP number 3. Prominent transgender characters are MANDATORY in the new series and other steps will be taken to drive every last reactionary out of what's left of the fan-base.

It becomes studio policy to viciously copyright strike anyone uploading video of retconned parts of the IP to any platform as well as to bully journalist insiders with access into adopting the new line by excluding anyone who disagrees with it from access or favor.
