W.D. Gaster

[leonazul19]

I know that if you hack undertale and set "fun value" to 69 a gray door will appear and W.D. Gaster will be in that room but what i want is to see your theories on who he is in the comments knock yourself out theorists

[Killure]

He's sans and papyrus' brother. When you shift around the coding you can even find his "followers", there's three. They explain more. Like how Gaster built the Core and somehow had an accident there costing his life. That's pretty much all I know but its super interesting

[responsible bedtime]

he's sans and papyrus's (older?) brother.
he built the CORE and a time machine and the determination extractor and fell in to the CORE.
it's theorized that he lives on as part of sans, since sans seems to own a few demonic skeleton head weapons called "Gasterblasters".

* so now that i know you're a time traveller, 
  i can let you in on another secret. 
* imagine that this world is like lines of code
* and every choice you make 
  changes something in that code 
* creating a different string of data. 
* we call these codes timelines. . . 
* parallel universes. . . 
* all originating from the same source code.
* no universe is exactly the same.
  unbelievable, isn't it?
* i couldn't believe it for myself at first.
 
* now normally it's impossible to see things 
  beyond our own timeline, 
* but an old friend of mine found a way.
 
* you see it all depends on your FUN value.
* as you can probably imagine, 
  FUN is yet another acronym. 
* it stands for the "frequency of universe". 
* by altering this value 
  it allows us to catch glimpses 
* into other timelines. . . 
  other realities. . . 
* other universes.

* but only those with great power
  can alter these values on their own.
* my "friend" tried to find the secret
  to this power.
* they hoped it could free us. . .
* but. . . well. . .
* to be honest i have no memories
  of them myself.
* just a feeling you know.

* why do i believe all this?

* heh heh. . . well
* i've been thinking lately.
* if you met yourself 
  in another universe. . .
* would you really be exactly
  the same as you?


* by the way, kid.
* i remembered
  what i was going to tell you earlier.
  back at grillby's.
* me and papyrus's last name.

* . . . it's gaster.

[Ragingsword]

I'm guessing he's sans and papyrus's uncle
