Is Gaster actually an important character?

[Bellatrix]

People seem to link everything mysterious back to Gaster.
Gaster seems to have literally no bearing on the plot of Undertale, other than that he designed the core and has some vague links to Sans.
His whole gimmick in Undertale seems to be that he somehow erased almost all traces of his existence, likely by accident; anything that refers to his existence is likely in a similarly tenuous state of existence.
He's a fascinating character, sure, but you could erase him from Undertale and it wouldn't feel like anything is missing.

For Gaster to actually be an important character in Deltarune that's been driving the plot would be a complete inversion of what he is in Undertale.

Also, for a bit of outside-of-the-game logic as to why Gaster isn't particularly important in Deltarune, Gaster is a relatively new character. There's apparently evidence based on file ordering that Gaster was a late addition to Undertale, which would mean he was an afterthought. Given that Deltarune would have already had much of the plot figured out at this time, if there is some super important sneaky character in Deltarune it would predate Gaster.

it's fnaf tier "this one guy does all this stuff!!!!" that's really mind numbing to listen to consistently. There's zero evidence of Gaster doing anything and almost all plotpoints in this game seem to be red herrings.

Is he an Egg or is he a man? He is crazy, so he is prolly Manegg. Ha ha.

yeah ,. i been sayign this too.
gaster isnt even canon.
there might be nods and winks, but DR ch1 showed us that nods and winks werrte intended for US the player, and had no bearing on the plot.
( liek snas and his brother, the fact you knew who he was bc of undertale )

there's a voice, but I think it's the voice of other players playing a game simialr to deltarune. and once in awhile oyu get solme weirdoes that really bend the in -game logic to find hiudden stuff.

my guess is jevil and spamton are allegories for such meddling.

Gaster is a weird entity, we don't even know what he really looks like (the mystery man could very well have been a reg herring, and I could see Toby revealing his true design to be completely different). He's associated with the garbage noise you hear in the dark world, and the few in-game sequences he's linked to somewhat relates to Deltarune's main plot.
The secret bosses all have white or grey faces, which are possibly references to the gaster followers. Hell, the custom character parts have file names.
So far there's only been hints to Gaster's presence, and that excites people. Until Toby releases more chapters, we won't know exactly how involved he is and what his motives are.

Gaster is a really important character, and in Deltarune is even more important. He proves that Undertale and Deltarune are in the same universe, because back in 2015, deltarune.com already existed. In the web you could find the entry number 17, and some time later, the legend of Deltarune. He is like G man but in Undertale / Deltarune

[HeroBehindNothing]

except gman actually is important to the plot of half life while gaster has less influence on the plot of undertale or deltarune than mettaton or alphys or any other semi-significant character. We dont know if gaster even exists in Deltarune. The "garbage" noise could very well be toby fox using the ost for a redhering or he finds it appropriate and again.

the motto of the fanbase is that everything is Gaster related until proven otherwise

[Knud den Store 🧙‍♂]

Gastler created Chara and he invented the method to extract souls out of humans which is a pivotal point.
Chara also looks messed up like Gastler.
Sans beam attack are referred to as Gastler's Canons.

Gastler is behind the corruption of both Jevil and Spamton.
Gastler might be trying to kill Chara.

I doubt Chara was evil but was equally corrupted like Jevil and Spamton, clearly lost it. Gastler is hiding in the space between dimensions and do not wishes to act directly, perhaps Chara's / Kris power is far too great.

It is my fan theory that Chara has lost significant amount of power since the end of Undertale, the reason why the player and Frisk are regaining control of Kris is because they are fighting back.

Can I offer you an egg in these trying times?

gaster is ptrple guy 0_0

Here's yet another reason Gaster won't be important in Deltarune:
There's been too many clues. If it's dead obvious, it won't be exciting. They're probably red herrings instead.
And most of the "clues" aren't necessarily connected to Gaster anyway, just assumed to be. Like the man behind the tree: There's no reason to believe he's Gaster other than that no one else fits the bill of an unknown man behind a tree. Maybe he's just... An unknown man? Someone that is completely unknown, or hinted at in such vague ways as to not be given much thought.

now i feel like gaster could literally show up and have a big sign pointing towards him saying "W.D. gaster" like pipis and people in this thread would still think it's a red herring

ah yes, the writing style of the cryptic tweets before the releases of each chapter, the intro sequence body parts being called "goner", having a track called ANOTHER HIM referencing must_st_him, mus_smile playing on the cell phone, seam saying "darker, yet darker", the bunker playing mus_smile slowed down by 666%, the inclusion of gaster follower #3, don't forget being a direct reference to sans' secret room, spamton's phone playing the cell phone's garbage noise after he left, flashback being literally just gaster's theme with a different soundfont, and the general importance of darkness (which is basically gaster's entire thing) are all clearly just red herrings or coincidences, makes a lot of sense to fill the game with hints to a very popular secret character that probably only existed to tease this game and then just ignore them all completely. honestly, i feel like making all of the seemingly big cool details and secrets just end up being literally nothing would just make the game kinda bad

but if you're talking about him not being important to the main plot about kris, the knight and the fountains then you'd probably be right, he'll most likely be just a really hard to find secret boss on the last chapter with some meta lore about timelines and connections between deltarune and undertale that can be easily skipped or missed

Actually, all of his followers have appeared now, if I'm not mistaken. Along with all the goners except clam girl, iirc.

lmao I'm going to laugh my ass off when Gaster is revealed to not actually exist, to just be nothing more than the collective fever dream of multiple schizo bosses, and all those theory-crafting vids and never-ending threads over 5 years go to waste.

Seriously Gaster is literally just an anagram for 'easter' with a g added. Get it? As in 'easter egg'? Basically an inside joke that's gotten blasted to ridiculous proportion because people have to attribute greater meaning to things, like inside jokes, when even the writer probably hadn't even given it a second thought.

Reminds me of how the Bite of '87 in FNAF was just a throw-away one-liner until the community worked itself into tism fits over it so much that the writer felt pressured to give it greater meaning where there was none.

sans is also a joke character, because he's the font 'comic sans', but that didn't stop him from getting lore and importance in the overall story. plus, deltarune was being worked on since early 2012, and references to grandpa semi (which is supposedly the prototype gaster) exist in the demo and got scrapped before the game was even close to releasing, so he had a lot of time to think about gaster's role in what would become deltarune, and his addition in late development in undertale is most likely because he knew adding extremely rare easter eggs before actually finishing the important parts of the actual game would be a really stupid move
