Doctor W.D. Gaster

**Doctor W.D. Gaster** is a major character in *Deltatraveler* and the one implied to being conducting an experiment involving the Delta Warriors traveling through different worlds.

During the Normal Route and Obliteration Route, he will communicate with Kris directly either when they are sleeping through dreams, or while they are awake by freezing time from Kris's perspective.

He's currently physically found in Hard Mode at the end of LOSTCORE in his laboratory, observing Frisk's actions, with his dialogues changing based on their choices. Additionally he can be found in Section 3 by entering and exiting the snowman room repeatedly, similar to the man behind the tree rooms in Deltarune, and once again his dialogue is different depending on what route you are on.

Unlike all other characters which always use a specific and constant text sound when they speak, Gaster will instead communicate with a "text-to-speech" manner everything he says in his textbox (unless its written in Wingdings, in which case he will resort on a generic text sound). Gaster also seems to have some amount of meta-knowledge, being able to tell if the Player has already completed Hard Mode at least once, as well as if they are using a program to record *Deltatraveler*.

* 👌☼✋☹☹✋✌☠❄ *[BRILLIANT]*
* ✋❄ ☟✌💧 👌☜☜☠ *[IT HAS BEEN]*
* 🏱☹✌👍✌❄☜👎 *[PLACATED]*
* MHH...
* IT APPEARS THAT YOU HAVE FINALLY ARRIVED.
* ALLOW ME TO PROPERLY INTRODUCE MYSELF.
* MY NAME IS **DOCTOR W.D GASTER**.
* I AM QUITE SURPRISED WITH THE OUTCOME OF THIS EXPERIMENT.
* ESPECIALLY WITH HOW DIFFICULT IT WAS TO PROCURE.
* MY POWER IS NOT AS USEFUL AS I WOULD LIKE...
* NONETHELESS, THIS HAS BEEN A SUCCESSFUL EXPERIMENT.
* BUT...
* THIS IS NOT THE PRIMARY EXPERIMENT THAT I AM CONDUCTING.
* YOU MUST LEAD THE DELTA WARRIORS TO THIS VERY LOCATION.
* YOU MUST GET HERE WITHOUT MY DIRECT INTERFERENCE.
* THEY MUST FACE THE HARDSHIPS OF TRAVEL.
* THE GREY DOORS ARE YOUR ONLY PATH TO PROGRESSION.
	+ I CANNOT SHAKE THIS FEELING THAT YOU KNOW THIS ALREADY. **[First time reaching the end of Hard Mode, and a recording program is detected]**
		- I DO HOPE THAT YOU ARE NOT ATTEMPTING TO GET A REACTION FROM ME.
	+ BUT I IMAGINE YOU HAVE ALREADY KNEW THIS. **[First time reaching the end of Hard Mode and Section 2 was completed]**
		- PERHAPS YOU WERE PERPLEXED BY THE QUEEN'S HOSTILITY.
		- ...
		- ONLY YOU KNOW THE ANSWER TO THIS.
		- I DO HOPE THAT THIS IS NOT JUST AN ANSWER TO YOU. **[A recording program is detected]**
			* AN ANSWER THAT YOU COULD MAKE AVAILABLE TO THE WORLD.
			* THAT WOULD BREACH OUR PRIVACY, OF COURSE.
			* YOU WOULD NOT BE DOING SUCH A THING, WOULD YOU?
	+ BUT I IMAGINE YOU HAVE ALREADY HEAR THIS BEFORE. **[Hard Mode was completed at least once]**
		- ...NOT THAT I WOULD KNOW, OF COURSE.
		- IT WOULD BE TERRIBLE FOR ME TO LIE TO YOU KNOWINGLY. **[A recording program is detected]**
			* JUST AS IT WOULD TO BREACH OUR PRIVACY.
			* YOU WOULD NOT BE DOING SUCH A THING, WOULD YOU?
* NONETHELESS...
* I WOULD LIKE TO COMMENT ON AN ASPECT OF THIS EXPERIMENT.
* YOUR PATH.
* THE CHOICES THAT YOU MADE TO ARRIVE HERE.

##### **No monsters were killed**

* YOU HAVE DONE EXCELLENTLY IN NOT HURTING ANYONE. **[Flowey was spared]**
	+ THE MONSTERS THAT YOU HAVE ENCOUNTERED...
	+ YOU GAVE THEM YOUR MERCY.
	+ BUT STRANGELY...DESPITE THE HYPOCRISY IN DOING SO...
	+ YOU EVEN ALLOWED THE FLOWER TO GET AWAY.
	+ EVEN THOUGH HE CHALLENGED YOU TO KILL HIM.
	+ IT SEEMS RATHER COUNTER-PRODUCTIVE TO DO SO.
	+ TO SPARE THE LIFE OF A RUTHLESS MURDERER.
	+ AT LEAST, THIS BEHAVIOR GOES AGAINST MY FINDINGS.
	+ I DO WONDER...
	+ ...IF YOU UNDERSTAND THE CONTEXT OF THE FLOWER.
* FOR THE MOST PART... **[Flowey was killed]**
	+ YOU HAVE DONE EXCELLENTLY IN NOT HURTING ANYONE.
	+ THE MONSTERS THAT YOU HAVE ENCOUNTERED...
	+ YOU GAVE THEM YOUR MERCY.
	+ ... HOWEVER...
	+ YOU MADE ONE EXCEPTION AT THE LAST MINUTE.
	+ YOU DECIDED TO TAKE THE LIFE OF THE FLOWER.
	+ THE ONE THAT ARRIVED BEFORE THE OTHERS.
	+ THE ONE WHO...
	+ ...WELL... I WILL SPARE YOU THE DETAILS.
	+ BUT I WILL SAY THIS.
	+ THERE IS A CAUSE AND EFFECT FOR EVERYTHING.
	+ WHY WOULD A FLOWER ACT IN SUCH A WAY...?

* YOU ALSO FOUND IT. **[The Egg was obtained]**
	+ THOUGH... **[The Egg wasn't exchanged for the Chocolate Candy]**
		- I DO WONDER...
		- WOULD IT PERHAPS OFFER A TRUE BENEFIT?
		- PERHAPS AN OFFER...
		- ...OF AN EGG.
	+ AND YOU TRADED IT FOR A CANDY. **[The Egg was exchanged for the Chocolate Candy]**
		- OH, HOW YOUR CURIOSITY REWARDS YOU.
		- JUST AS MINE REWARDS ME.
		- ...
		- AT LEAST, MOST OF THE TIME.

* AND IF I MAY ADD... **[BLADEKNIGHT was fought]**
	+ YOU DID NOT NEED TO FIGHT THE ABANDONED VESSEL.
	+ BUT I SUPPOSE YOU DID SOMETHING GOOD IN THE END.
	+ I AM UNSURE OF IF YOU CAN UNDERSTAND ITS LANGUAGE...
	+ BUT THE KINDNESS THAT YOU GAVE IT...
	+ CHANGED ITS MIND.

##### **Anyone (but Flowey) was killed**

* NOW, UNLIKE FOR MY PRIMARY EXPERIMENT.
* I HAVE TRACKED THE NUMBER OF MONSTERS THAT YOU HAVE SLAIN.
* YOU HAVE ELIMINATED **X MONSTERS** ON YOUR JORNEY. **("X" is the number of monsters killed.)**
	+ I MUST ASK YOU. **[Napstablook wasn't killed]**
		- HAVE YOU CONSIDERED THE LIVES OF THE MONSTERS?
		- THEY HAVE FAMILIES THAT THEY WILL NEVER SEE AGAIN.
		- ...OR IS THIS NOT SOMETHING THAT YOU CARE FOR?
		- IS THIS JUST AN EXPERIMENT TO YOU AS WELL?
	+ WHAT DID YOU FEEL WHEN YOU SAW **"24 left"**? **[Napstablook was killed]**
		- WAS IT PERHAPS FEAR?
		- WAS IT GRATIFICATION?
		- DID YOU PERHAPS FORGET TO SLAY THE REST OF THEM?
		- OR WAS THIS INTENTIONAL?
		- AND YOU REMORSEFULLY REGRETTED YOUR ACTIONS?

* ...
* THIS IS SOMETHING THAT YOU CAN ONLY ANSWER TO YOURSELF.
	+ BUT STRANGELY...DESPITE THE HYPOCRISY IN DOING SO... **[Flowey was spared]**
		- YOU EVEN ALLOWED THE FLOWER TO GET AWAY.
		- EVEN THOUGH HE CHALLENGED YOU TO KILL HIM.
		- IT SEEMS RATHER COUNTER-PRODUCTIVE TO DO SO.
		- TO SPARE THE LIFE OF A RUTHLESS MURDERER.
		- AT LEAST, THIS BEHAVIOR GOES AGAINST MY FINDINGS.
		- I DO WONDER...
		- ...IF YOU UNDERSTAND THE CONTEXT OF THE FLOWER.
	+ ... HOWEVER... **[Flowey was killed]**
		- THERE WAS ONE ENEMY THAT I DID NOT COUNT IN THE TALLY.
		- YOU DECIDED TO TAKE THE LIFE OF THE FLOWER.
		- THE ONE THAT ARRIVED BEFORE THE OTHERS.
		- THE ONE WHO...
		- ...WELL... I WILL SPARE YOU THE DETAILS.
		- BUT I WILL SAY THIS.
		- THERE IS A CAUSE AND EFFECT FOR EVERYTHING.
		- WHY WOULD A FLOWER ACT IN SUCH A WAY...?

* AND IF I MAY ADD... **[BLADEKNIGHT was fought]**
	+ YOU DID NOT NEED TO FIGHT THE ABANDONED VESSEL.
	+ BUT I SUPPOSE YOU DID SOMETHING GOOD IN THE END. **[Spared it]**
		- I AM UNSURE OF IF YOU CAN UNDERSTAND ITS LANGUAGE...
		- BUT THE KINDNESS THAT YOU GAVE IT...
		- CHANGED ITS MIND.
	+ IT IS ENOUGH THAT ITS EXISTENCE WAS DOOMED. **[Killed it]**
		- IT IS WORSE THAT YOU DECIDED TO END ITS POOR LIFE.
		- HOWEVER...
		- THAT MAY BE THE BLESSING IT WAS LOOKING FOR.
		- AS ITS OWN WILL COULD NOT UNDO ITS OWN LIFE.

* NOW, UNLIKE FOR MY PRIMARY EXPERIMENT
* I HAVE TRACKED THE NUMBER OF MONSTERS THAT YOU HAVE SLAIN.
* YOU HAVE ELIMINATED **X MONSTERS** ON YOUR JORNEY. **("X" is the number of monsters killed.)**
* IT IS QUITE INTERESTING.
* THE LENGTHS THAT YOU WILL GO TO GAIN STRENGHT.
* MURDER. MANIPULATION. POSSESSION.
* RIGHT NOW, I CAN FEEL ANOTHER PRESENCE WITHIN YOU.
* ONE THAT IS VENGEFUL AND WILLING TO END EVERYTHING.
* AFTER ALL...
* YOU HAVE MURDERED THEIR BEST FRIEND.
* *Frisk moves forward a few steps.*
* AH, I DO BELIEVE THEY ARE HEARING ME AS WELL.

##### **After all other dialogues branches have been exhausted**

* Gaster: BUT REGARDLESS OF YOUR PATH...
* Gaster: THERE IS BUT ONE MORE THING THAT WE NEED TO DO.
* Gaster: WE STILL NEED TO CONCLUDE THIS EXPERIMENT.
* Gaster: THEN, ONCE WE ARE DONE, WE MAY GO OUR SEPARATE WAYS.
* Gaster: SHALL WE GET STARTED?
* *Dess Holiday suddenly enters the scene.*
* Dess: Oh my GOD, can you shut up, it's like 3AM.
* Dess: !!!

### **Section 3's Secret**

* Gaster: BACK IN MY YOUTH, BEFORE I WAS ASSIGNED ROYAL SCIENTIST...
* Gaster: I WAS BUT THE ROYAL MAGE.
* Gaster: IT WAS A FAMILY LINEAGE FOR EONS.
* Gaster: WHEN I DISCOVERED HOW TO CONVERT HOTLAND'S MAGMA INTO ELECTRICITY...
* Gaster: IT WAS POSSIBLE TO POWER ABANDONED HUMAN APPLIANCES FOUND IN WATERFALL.
* Gaster: FROM THEN ON, THE FAMILY POSITION BECAME THAT OF SCIENCE.
* Gaster: BUT THE LINEAGE ENDED WITH ME.
* Gaster: IT WAS WHEN THE DREEMURR CHILDREN DIED.
* Gaster: FROM ASRIEL'S DUST LAID A RED HUMAN SOUL.
* Gaster: FROM ASRIEL LEAVING WITH IT, I FIGURED THE BARRIER UTILIZED SOUL POWER.
* Gaster: I UNOFFICIALLY INVESTIGATED THE HUMAN SOUL AND ITS BEHAVIOR.
* Gaster: PERHAPS I COULD DISCOVER A WAY TO BREAK THE BARRIER...?
* Gaster: HOWEVER, AS MORE HUMAN SOULS CAME INTO THE KING'S POSSESSION...
* Gaster: I NOTICED SOMETHING PECULIAR.
* Gaster: THE RED SOUL WAS COMPLETELY IMPERVIOUS TO DAMAGE.
* Gaster: UNLIKE THE OTHER HUMAN SOULS...
* Gaster: WHICH WOULD SHOW SIGNS OF DAMAGE UPON TAKING ITS INTERNAL SUBSTANCE.
* Gaster: AS THE POWER SOUL EXPERIMENT CAME TO AN INCONCLUSIVE CLOSE...
* Gaster: I HAD TO KNOW HOW RESISTANT TO CHANGE THE RED SOUL WAS.
* Gaster: MY TIME OF "FALLING" WAS COMING CLOSE.
* Gaster: WITH WHAT LITTLE MORTAL LIFE I HAD, I RESIGNED FROM MY POSITION...
* Gaster: TOOK THE RED SOUL WITH ME TO THE CORE...
* Gaster: AND CLUTCHING IT IN MY GRASP...
* Gaster: LEAPED IN THE OZONE BELOW.
* Gaster: WITHIN MERE MOMENTS, I FELT MYSELF BEING SCATTERED AND SHATTERED.
* Gaster: AND YET MY GRASP ON THE SOUL HAD NOT LOOSENED.
* Gaster: IT WAS ONLY WHEN MY MIND BEGAN TO RIP APART DID I DECIDE TO RELEASE.
* Gaster: AND HERE I WAS.
* Gaster: SURROUNDED BY AND SURROUNDING EVERYTHING AND NOTHING.
* Gaster: YET... SOMEHOW...
* Gaster: I FELT THE RED SOUL NEAR ME.
* Gaster: IT IS ALWAYS NEAR.
* Gaster: DESPITE BEING ABLE TO RECONSTRUCT A NEW RESIDENCE HERE...
* Gaster: DESPITE BEING ABLE TO REFORM MY MIND INTO ONE ESSENCE...
* Gaster: I COULD NEVER ESCAPE.
* Gaster: I COULD ONLY LOOK IN FROM THE OUTSIDE.
* Gaster: ONLY THROUGH THE VIEWPORT OF THAT VERY SOUL.
* Gaster: WHEREVER IN TIME AND SPACE IT RESIDES.
* Gaster: I ONLY DESIRE TO BECOME WHOLE AGAIN.
* Gaster: AND FOR A LONG TIME, I FELT THAT I WOULD REMAIN HERE, STUCK IN ETERNAL PURGATORY.
* *Gaster turns his head slightly*
* Gaster: ... **[Normal Route]**
	+ Gaster: THAT IS...
	+ Gaster: UNTIL I FOUND IT.
	+ Gaster: THE DARK FOUNTAIN.
	+ Gaster: FROM UNDER THE EARTH.
	+ Gaster: THERE IS A DARK MAGIC THAT CAN ENVELOP ITS SURROUNDINGS AND BECOME A NEW WORLD.
	+ Gaster: THAT YOU KNOW ALL TOO WELL, KRIS.
	+ Gaster: ... SO THEN.
	+ *A sprite of Gaster appears looking at the screen with strange yellow and pink eyes.*
	+ Gaster: SHALL YOU HELP ME CREATE A NEW WORLD, [Player's Name]?
	+ *The room returns to normal.*
	+ Susie: Kris...?
	+ Susie: What the hell were you doing?
	+ Noelle: You were kind of... wandering.
	+ Noelle: You weren't gonna...
	+ Susie: ... Gonna... what?
	+ Noelle: ...
	+ Noelle: ...Nevermind.
	+ Noelle: Maybe they just... needed a minute.
	+ Noelle: These woods are kinda hypnotic in a way.
	+ Susie: Okay, this is getting weird.
	+ Susie: Let's just go.
* Gaster: IT IS TORTURE, KRIS. **[Obliteration Route]**
	+ Gaster: THE REGRET I FEEL DAILY HAUNTS ME.
	+ Gaster: HOW EVERYTHING COULD HAVE TURNED HAD I NOT JUMPED.
	+ Gaster: MAYBE MY NAME WOULD LIVE ON IF I HADN'T "GONE MISSING."
	+ Gaster: MAYBE YOU WOULD NOT BE CONDUCTING YOUR OWN EXPERIMENT.
	+ Gaster: WHEREIN YOU OBLITERATE EVERYTHING IN THESE WORLDS.
	+ Gaster: YOU BARELY EVEN CONSIDERED A MORE TAME ROUTE.
	+ Gaster: HOW SADISTIC...
	+ *A sprite of Gaster appears looking at the screen with strange yellow and pink eyes.*
	+ Gaster: PERHAPS WE ARE MUCH THE SAME, [Player's Name].
	+ *The room returns to normal.*
