ALPHA404: What's that?
walks towards the portal then an arm comes out of the portal and grabs ALPHA404
ALPHA404: What the?!?!
ALPHA404 saw a figure and the figure knocks him out
ALPHA404: Ugh what happen?
ALPHA404 sees omniglitch sans (fanon), beyond-omni gaster, error404, and his henchman
ALPHA404: Hey wake up
Omniglitch: What?
Beyond-omni: did someone knock me out
error404: That guy is going to pay
???: Well hello there 
All: Who are you?!
???: Just call me servant
ALPHA404: servant huh. What a weird name
???: That's my nickname
ALPHA404: Okay
Servant: I notice that you guys are extremely strong
ALPHA404: Of course
Servant: But not strong enough
ALPHA404: What do you mean?
Servant: Attack me
ALPHA404: Umm okay?
ALPHA404 punches servant but misses he punch him again and again 300 times
Servant: All of you don't hold back fighting me
ALPHA404: you do realize that's practically suicide
Servant: I don't care
ALPHA404: Very well
All of them attacks at servant but misses ALPHA404 and error404 transforms into their most powerful form but still misses this keeps going on over 5000000 millenniums
Servant: Your attacks are very slow
ALPHA404: OH REALLY
Servant: it's time to put to sleep
Servant snaps his fingers and instantly knocks out every opponent
Servant: Hey wake up.
ALPHA404: What, oh it's you
Servant: what missed me something?
ALPHA404: No
Servant: Okay then It's time for a montage
ALPHA404: Wait wha-
Servant: Me talking to you about hard questions that takes a lot of time
ALPHA404: Wait what?!
After waiting for unbearable centi-cosmological decades (1 decillion years oh did I mention it gets increasingly harder every xentojiffy It takes around (insert huge number here x insert huge number here = huge number x huge= ... every xentojiffy) omniscients 
Servant: fighting
After fighting for centi-cosmological decades
Servant: Fighting until you hit me
After missing for centi-cosmological decades
Servant: Now attack with all you got with no holding back
After attacking Servant for centi-cosmological decades
Servant: Spirit
After making their spirits even more harder to break
Servant: Speed
After making them faster
Servant: Team work
After getting better at team work
Servant: Now 7 traits (What I mean is that the sanses are getting all the traits that a human can have and getting better at it such as determination they're getting better at using the determination and having more abilities of the 7 traits)
Servant: Now stamina
after making their stamina's a lot stronger
Servant: Martial arts
After you get the Idea
Servant: Vision (Which is kinda like the eagle vision from assassin's creed just a lot more powerful)
Servant: Hiding
Servant: Seeking
Servant: Durability
Servant: Agility
Servant: Dodging
Servant: Regeneration
Servant: speed, lifting strength, striking strength, destructive capability, durability fighting skill and power 
Servant: break after a xentojiffy break ALRIGHT LET'S DO THAT AGAIN
All: WAIT NO!
this repeats like huge number at the same time and we all know what's going to happen we take huge you know what you get the idea
All: Will this end? 
Servant: No, and worst of all you're doing the same high scores as you first fight me, so you're doing the same
But what they didn't know that they were actually getting better by getting better I mean a lot and the reason why they getting the same high score is because there a cap to how powerful you can get but when you get out of the antarctic empire you have those benefits from training in the antarctic empire
Servant: Alright you can go now or can you nah I'm just kidding you're free to go
Omniglitch: Really?
Servant: Yep
Summons a portal
Servant: Just go through the portal and you'll be free unless you want to train. BTW protect sans at all cost
Error404: Huh why?
Servant: Just protect him okay
Error404: Okay okay We'll protect sans
Servant: Also don't be spotted by sans okay
ALPHA404: You got that coach
All of them goes through the portal
Servant: sigh cut's off his ring finger
the blood morphs into technoblade
Technoblade: Hello
Servant: what is it
Technoblade: nothing much player are you really a coach though?
PLAYER: No
... Undertale ddd gaster dialogue
Eanaro: Life starts anew and yet it's the same old story forever stranded, forever living foregone deaths such is the destiny of those resigned in these timelines
Gaster: destiny? can't say I've ever had one
Eanaro: And yet here you are
Gaster: by unlikely circumstances
Eanaro: Or by a destiny you thought you never had
Gaster: And yet, even now the a the Absolute truth (All dimensions wiki) barely acknowledges my existence
eanaro: And yet here you are bound, to this twisted fate
Gaster: It's like some cruel joke
Eanaro: Unfortunately, it's this type of joke that I've been forced to live with, for what seems like eternity
Gaster: Speaking of which how long has it been?
Eanaro: Time is seldom kept now... Given the circumstances
Gaster: when will a glimmer of hope ever come forth? If only I were in control, no one would ever have to suffer like they are now
Eanaro: And yet it's frightening to think that such good intentions can lead to 2 drastic outcome, that still mean the same. To liberate everyone either by life or death pacifist of genocide
Gaster: STRANGE. Hm could you repeat that again?
Eanaro: You should go
Gaster: Is it time already?
Eanaro: I sensed a timeline distortion... and I feel as if
Gaster:...I sensed their presence too
Eanaro: Well good luck as always
Gaster: Same to you
NO USE HIDING TEAM NULL
Gaster: I new that eventually fate would bring all of you here. Does encountering something new excite you guys? You must be quite intrigued now Quite frankly so am I I'm glad this encounter finally happen I can now conduct my experiment on all of you and there's nothing you guys can do about it strike me if you guys wish you guys can't kill someone that doesn't even exist well within your world that is take goner kid for example the absolute truth fails to register your attacks as valid due to the fact that the Absolute truth doesn't register Goner kid as an existent entity FORTUNATELY GONER KID IS STILL NATIVE TO UNDERTALE UNIVERSE AND BEYOND TO SOME EXTENT HENCE WHY GONER KID CAN STILL INTERACT TO UNDERTALE AND BEYOND ALL GONER KID NEEDED WAS SOME SORT OF OPENING INTO UNDERTALE AND BEYOND AS WELL AS VESSEL TO STABILIZE THEIR EXISTENCE TOO BAD SUCH CHANCES DON'T LAST VERY LONG BUT HERE? I GOT ALL THE TIME IN THE WORLD WELL... UNTIL YOU DIE FROM THERE I HAVE PLANS TO TAKE OVER YOUR MIND AND WHO KNOWS MAYBE KILL YOU AND DESTROY EVERY EVIL SANSES WHILE I'M AT IT INDEPENDENT OF YOUR CONTROL BASICALLY GAME OVER
Gaster: PITY,I COULD'VE ACHIEVE A LOT WITH POWERS LIKE YOURS 
gaster summons 8 hands that shoots bullets in all direction at high speeds
Cybervirus404 went to punch Gaster but a static effect nullify the attack
Gaster: SCIENTIFIC BREAKTHROUGHS, REVOLUTIONARY INVENTIONS, ALL THANKS TO SUCH POWER THAT CAN OVERRIDE FAILURES SO LONG AS YOU HAVE THE DETERMINATION
GASTER: ALAS, GOOD THING CAN HAPPEN TO BAD PEOPLE
Null: Of course
gaster summons a black hand that shoots 8 bullets in 8 directions while a gaster blaster is appearing above team null shooting all of them then the hands bullets turn into white bullets
Gaster: AND LIKEWISE BAD THINGS CAN HAPPEN TO GOOD PEOPLE
Gaster summons 4 hands spinning while each shooting 2 bullets at the same time the bullets bounce off the walls gaster hands start to shoot different bullets while in the center gaster shooting round balls
Gaster: WOULD I CONSIDER MYSELF A GOOD INDIVIDUAL THOUGH?
Gaster summons a purple hand that binds team null with the purple soul and blue and orange hands start to come out of the purple hand but sometimes the static effect block the team null vision
Gaster better than you at least
Summons 2 gaster blaster at each side of every member of team null A huge blaster shoots out an orange blast and leave a shock wave then a gaster blaster shoots out a blue blast that leave a shock wave

Gaster: All you guys shallow mind can never achieve anything revolutionary, beyond such transient, lowly desires
Gaster summons 10 hands one of them grabs null sans and smash him into the ground while spawning 10 gigantic gaster blasters and shoots all of them at team null
Gaster: ALL YOU DO IS PERSIST, MEANINGLESSLY, AND WITH ANNOYING HIGH LEVEL OF IGNORANCE
Gaster: ENOUGH FOOLERY
Gaster summons 8 hands and the hands shoot at every direction then a gigantic hand start to shoot out thin bullets while the smaller ones is spinning while shooting white balls then the 8 hands make a barrier to prevent members of team null escaping or entering then 2 black hands start to shoot bullets at 2 direction while spinning the 2 hands then disappear and the 8 hands start to close the distance between gaster and the center gaster shoots out a barrage of bullets in every direction the 8 hands turns into a gaster blaster and start sucking up everything before shooting Team null members has been defeated
But that was all null sans dream little did he know this dream would come true if eanaro didn't save them
