No Snap in Hell's Kitchen

There's the Red Skies Crossover, where a huge, cataclysmic status quo shaking event is barely acknowledged in works set in the same universe around the same time frame. And then there's this trope which goes way beyond that to its logical extreme: a work in a shared universe isn't affected by a massive change in the status quo.

Maybe it's a work where the author has a lot more creative control than the studio. Maybe the work only exists in Broad Strokes compared to the rest of the universe. Or maybe the writers of the work don't feel like including the particular event in their work.

Whatever the reason may be, the work is completely isolated from the massive event taking place in the rest of the universe. Not even red skies, not even a token mention of the event, nothing.

Often leads to Continuity Snarl and Exiled From Continuity.

Examples of No Snap in Hell's Kitchen include:

• Several television shows in the Marvel Cinematic Universe, such as Agents of S.H.I.E.L.D., aren't affected by the Snap of Avengers: Infinity War or the five years Time Skip and the Blip in Avengers: Endgame. The same goes for Runaways, Cloak and Dagger and Helstrom.
• Masked Rider is part of the main Power Rangers universe, yet the show was never effected by the massive invasion of Earth in Countdown to Destruction. Furthermore, while the Megaforce Rangers get keys to all the past Rangers, they never get Masked Rider keys, nor is Dex seen in the final battle in Super Megaforce.
• None of the characters from Kong: Skull Island seem to be affected by the events of Godzilla: King of the Monsters. Skull Island and Kong do get namedropped a few times, yet when the time comes for all the Kaiju to be summoned in order to destroy the Earth, Kong and the Skrull Crawlers are noticeably absent.
• Doctor Slump never acknowledged all the times in the Dragon Ball franchise where either the Earth got destroyed, or the Moon got destroyed.
• Despite being established as being part of the Ghostbusters Multiverse, Filmation's Ghostbusters are completely absent from Ghostbusters Crossing Over .
