Dtale!Unknown!Sans

I did this in the night which means I have to do it tomorrow I really need to stop doing projects at night but that will most likely never change

Dtale!Unknown!Sans and Unknown!Dtale!Sans and Determined!Unknown!Sans are all different.

Story
He was living normally in his AU Named ???. Until Unknown!Gaster made DT but only 1 syringe since he was working on a experiment. But after a while his Universe started to collapse because something went horribly wrong maybe it was Unknown!Gaster's experiment. But Sans got out of there and grabbed a weird syringe with him and he became what he was he decided to take the DT syringe since he's got nothing else to lose. Once he injected it he became extremely more powerful and he roamed the Multiverse until he found out about The Dtale!Multiverse so he went there as he feels like that is his true home and he took the blue screen death screen with him. And he changed his appearance to look more like Dtale AU

Appearance
He wears the same shirt as Dtale!Sans and his pants are black with pink stripes and his shoes are the same. And he was a blue scarf since taking the something that wasn't supposed to be moved made his scarf turn blue and the letters on the black text box have been changed to red. And he bleeds less when he takes it off.

Personality
He is the depressed of the incident and even more depressed after taking DT since he could have used it to save someone from his AU like papyrus and after being in the DT Multiverse he doesn't hate Charas except the ones from like killer!Dtale and others and he still hates all of the other Charas which are not from the DT Multiverse except the ones who take the place of Sans or Papyrus. And whenever he hears the Name Papyrus or see him just like his original Self he will have an emotional breakdown but he will have an even severe one.

DeTermination bones
it's almost impossible to see since it's black but in a Ghostly form and do a lot of damage and also because it's glitched and he can change into blue or Orange or Red but they all looks the same so people who know about it need to be extremely careful. And in all of modes they all ignore invincibility frames and the bones are extremely fast almost impossible to dodge them.

DeTermination Basters
They are extremely powerful also glitched they also black and the Ghostly form and same as the bones he can turn it to Blue or red or Orange. And they also ignore invincibility frames and extremely fast even faster than Unknown!Dtale!Sans since Unknown!Dtale!Sans has a huge gap in the head

DeTermination Ghost
No attacks will work on him once he is in this state which makes them extremely powerful sadly though his attack will be reduced to 10 which is still good enough except when you're fighting against Gods so to counter this he summons a lot of blasters and bones. And he cannot feel any emotions during this state which gives them an advantage of some sort.

Immortality
It's unknown if he is Immortal but he is extremely difficult to kill but the reason why he possibly has Immortality is because he survived a attack from Dtale!Error404 and Dtale!Clans since he accidentally got hit in the crossfire, they were using almost all of their power and that makes Dtale!Unknown extremely powerful.

Create
He can create stuff he got it when he was fighting Ink since he got some weird paint on him which gave him the power and he can create AUs but not

Maker
A side effect of Create he can make living beings if he wants.

travel
He can travel to different AUs and jump into the code of the AU and he can travel to other multiverses the only multiverses that he traveled to is the original Multiverse and The RESETFELL Multiverse since he is aware that the Creator of Dtale is also the Creator of RESETFELL.

bounded by code
So much like his original Self and Geno once he's in the blue screen he cannot be damaged.

Coded barrier
He can make himself only to be damaged by code or glitch attacks.

Save, Load and continue
Very simple he can be resurrected from the dead and he can load can continue after death very simple.

Reset
Once he is in an au he can reset it if he wants.

AU Lock
He can lock a AU if He wants

ATK and DEF increase
He can increase his ATK and DEF by 99999, with no limit.

Termination
If he gets really stressed or angry his body will be covered in blue codes which have some red with them since it's filled with determination and his stats will be multiplied by 1000 and he will destroy anything that he sees and it will become a part of the blue screen death and cannot be reverted.

Unknown!Dtale!Sans
Friend and enemy. He is friends with the Unknown side but enemies with the Dtale!Sans side

Dtale!Dtale!Sans
Enemies? He hates the Dtale!Dtale since it's basically just Dtale but double the better DT, but he will appear on the 3rd genocide run since he doesn't want any AUs to suffer like he did.

Determined!Unknown!Sans
Friends. He enjoys being around him since he's technically another him, just a different story.

Error!Dtale!Sans
Ally. He met Error when he was talking to his original Self (Unknown!Sans) he was aware that Error was there so after his original Self left he talked to Error and they made Allys sometimes he will meet with Error talk about some other stuff. He also knows Error secretly works for Dtale!Virus404.

Unknown!Sans
Friends. He has met his original Self at this point, Unknown!Sans wasn't surprised that there was another Dtale version of him since there was already Unknown!Dtale!Sans and Determined!Unknown!Sans but they made friends and are a great Duo.

Dtale!Error!Sans
Ally. since he found out about Error!Dtale of course he found out about Dtale!Error at first Dtale!Error wanted to destroy Dtale!Unknown but after learning some things he had to become Allys with him.

Dtale Fatal Error
Ally. Dtale!Fatal is aware that Dtale!Unknown made Allys with Dtale!Error and Error!Dtale, so he became Allys with Dtale!Unknown since they both need something, Dtale!Fatal wants Papyrus Code while Dtale!Unknown need some things for a project that he's working on.

Dtale!Error404
Ally. since he got hit in the crossfire Dtale!404 saw him as a important person, originally Dtale!404 was going to take Dtale!Unknown as his henchmen but he realize that since he managed to survive the Crossfire he would just make him his Ally which work down in the end.

Error404
Enemies. since he used to be a Unknown!Sans, the original 404 will want him dead and they are still enemies but since he made an alliance with Dtale!404, Dtale!404 has mostly told original Error404 to go back to the undertale Multiverse or he will suffer the consequences and also saying that the Unknown that became a Dtale AU and is not his enemy anymore and that he should just focus on the original Unknown!Sans

Error!Sans
Enemies. Once again he used to be unknown so of course he's enemies with the original Error

Ink!Dtale!Sans
Enemies. since he destroys AUs sometimes, it makes him an enemy of Ink!Dtale.

Dream!Dtale!Sans
Enemies. Same reasons as Ink!Dtale

More relationships coming soon
