@extinct_hopes: Trivia: naming the fallen human "Gaster" resets the game to the title screen. Renaming the protagonist "Gaster" via save editing disables the reset option entirely, since the game restarts itself whenever Reset is pressed. Gaster's Theme is internally named "mus_st_him" rather than following the naming convention of other sound test tracks. "snd_mysterygo" uses the same piano sound as Gaster's Theme, which itself runs exactly 17 seconds — possibly nodding to Entry 17. Merchandise: Gaster's tarot card ("IX – The Hermit") was originally part of an Undertale tarot set but was removed and replaced with Gerson once the collection became officially licensed — suggesting it isn't canon (confirmed by Toby Fox). The mystery man briefly appeared on a Fangamer vinyl soundtrack box set cover before being removed from later prints, and was likewise removed from an iam8bit vinyl release and replaced with a save point (though "redacted" text remained on the cover). Possible references: examining a foggy fridge in the True Lab (if the vents weren't activated) describes a human-shaped figure believed to be Gaster — though it could also be the "watcher" amalgamate that covers the player with a blanket, or "the man" from Deltarune, described similarly elsewhere. The voice clips in room 264 are text-to-speech fragments reused from other files, possibly hinting at a meta connection to Toby Fox. The room 272 figure speaks in lowercase with an asterisk like Sans, while Entry 17 is uppercase without an asterisk, like Papyrus. Gaster may have built the Determination-extraction machine in the True Lab, since Alphys's Entry 5 admits she used existing blueprints — possibly the ones in Sans's workshop. Sans once joked in an official Tumblr post about researching Shyren's lower body — her head and body being separate creatures under an optical illusion — which might connect to the mystery man's face-on-body design, or imply he's actually a fused amalgamate of two monsters. An early Papyrus concept sketch Toby Fox tweeted included a note about someone else besides brother Sans, name censored — possibly Gaster, or possibly Grandpa Semi. The company name "Royal Sciences LLC," founded by Toby Fox in October 2015 to manage Undertale/Deltarune rights, may reference Gaster's role as Royal Scientist. Other trivia: Gaster is the only character with a unique font and voice clips but no dialogue portrait (Mettaton in his original form and Temmie also lack portraits, but use the Determination Mono font instead). The mystery man visually resembles Uboa from Yume Nikki and Dr. Andonuts from Toby Fox's EarthBound Halloween Hack. Gaster is frequently associated with the number 666 and repeating sixes — his font value in Entry 17 is 666, his unused datamined battle stats are all repeating 6s, and every fun-value event tied to him falls in the 60s range, with the fake hallway and mystery man room specifically requiring 66. Version history: v1.001 fixed a bug where Gaster's fun events were inaccessible without save editing due to a capitalization issue with the "fun" variable. v1.001-4 fixed a crash on PS4/PS Vita when naming a character "Gaster" instead of triggering the intended restart. v1.03-4 made entering "Gaster" as a name properly restart the game on PS4/PS Vita instead of crashing. v1.05 made the game restart immediately after the last letter of "Gaster" is typed, without waiting for confirmation. #deltarune #fnaf #fivenightsatfreddys #gamedev #indiegame
