Undertale Gaster Secrets

"Beware of the man who speaks in hands" Pulls out middle finger

It's rude to make a video about someone who's watching

Gaster Follower: After all, it’s rude to talk about people who are listening. Frisk: Doesn’t Gaster know that it’s rude to eavesdrop? Gaster: … what

Bro the fact that 7 years later the community is still alive really goes to show how amazing of a game this was (and still is). Clearly left an impact on games. Also, Merg, how do you even manage to see comments from so many old videos??? Like if I had like 800 videos, I wouldn’t care to check over it lol. Dedication my guy, or uh, determination. Wow this was a rant.

Just imagine New mother: Aww! Im gonna name him Gaster! pregnancy restarts

Gaster doesn't do anything. Nothing scary. Yet he's so unsettling. There's something about his very existence that horrifies me. The hints and the secrets. It scares me.

I know 6 years to late for the party. But the "Gaster" theme that is playing while encountering a Temmie is the same jingle that plays at the beginning of Metal Crusher, the OST that plays when you fight Metatton.

also theres this quick secret i found, if your doing a neutral/pacifist run (you have to hang out with papyrus to get his number) and in a specific place in hotland, he would say "oh your near core?" and if you try to call him back he would just say "..." with his sad face

Mettaton’s theme: plays slowly when you don’t feed temmie temmie flakes Merg: Gaster

Goner kid: “Please don’t think about this anymore.” Merg: ”SO I THINK...”

Probably a stretch but i have a theory that his "experiment" was the Deltarune Universe. He created this so monsters could happily live in the overworld. This would make sense because the goal of the scientist of the underground was to find a way to get out and restore peace. The "darkness" he's referring to may be the dark fountains spreading throughout the earth leading to the Dark Worlds

Beware the man who hearts comments after 7 years and beyond

An umbrella? But it's not raining... But "It's Raining Somewhere Else". In another timeline.

“It’s rude to talk about someone who’s listening.” ”so it’s not rude to listen to other people’s conversations?”

Regarding Room 264, Entry Number 17 is a missing lab entry in the True Lab during the True Pacifist Ending. While I haven't been big on the Undertale Story/Lore for years and years now, I believe the entry was originally going to be accessible to the player, as you'll notice in the video, the room does not cause a game crash like most rooms would.

I also think that the "You two"part of Gasters speech in room 264 means that Sans and Papyrus. And if you talk to the shopkeeper About the town, she says that the skelebros just "appeared" one day. MAYBE just MAYBE Sans and Papyrus just "appeared" Because when Gaster Shattered across time and space small remnants of him remained. The skelebros COULD be those "Remnants". Sans also mentions that He "gave up trying to go back a long time ago" And "getting to the surface doesn't really appeal anymore" That could because he came from a different timeline. Gasters timeline. Also in true lab, some text appears to be all lowercase, like Sans's font. That could imply that since sans may be gaster, he could be working with alphys on his "experiment". Also also if you beat sans twice he will give you a key to his room. If you do in a secret place there you will find a lab with blueprints on the floor. Could these be blueprints for the strange machine in true lab? Also Also ALSO there is a drawing on the wall, if you interact with it, it says "It is three figures you have not seen before" MAYBE This is Sans, Papyrus, and Gaster. MAYBE...

Merg: Does no hit sans Also merg: nearly dies on temmie

When Gaster fell into the Core, he split into a million pieces throughout the Underground. So he is always listening and watching.
