LucidVerse Nightmare sans
Nightmare- Leader and master strategist of the bad sans
(I may change things in the future, I just really want to get this out of my head)
This version of corrupted nightmare is still passive nightmare and not a parasite which plays a massive role in how he acts and will hopefully show the complexity and tragedy of his character as while yes nightmare in this multiverse is pretty much the main antagonist of this multiverse and he will earn that title with the evil things he will do in this story. The inclusion of nightmare still being passive and being able to create bonds with certain monsters and may be humans show that deep down there is a part of his old self trying to claw his way out of his sludge and tar prison.
In this au he is a weird mix of the ruthless canon nightmare and the fanon ‘dadmare’/ Good leader and what I mean by this is that he has a soft spot for his team due to the fact that he is still passive nightmare no matter how much he tries to shove his old self sensitivity and compassion he will see someone like him with Dust the feeling of being trapped, with killer its isolation and with Horror it is the feeling of being forced to do horrible things to survive and the fact that Undyne and Alphys betrayed horror like how he feels like he was pushed around by the villagers and forced to do something drastic.
However, when it comes to people outside of his faction, he retains a lot of his canon demeanour which includes sadism and his terrifying manipulative tendencies and how he is willing to do anything to get what he wants and achieve his goals, the goals being to take over the multiverse by corrupting it and then puppeteering from the shadows as he understands that while the universe needs positive and negative emotions to function doesn’t mean he can’t twist into his favour.
While I’m not an artist I have come to love the design choice some people have with nightmare making him more monstrous and eldritch looking and so, this version of corrupted nightmares design is far more monstrous and eldritch looking with him in most situations having sharp rows of Barbed teeth that come together to create a horrific and sadistic grin that goes all the way up to his ears which he can unhinge like a snake, multiple eyes across his body and tendrils and defaulting to the size of Asgore with monstrous bone crushing claws and long four tendrils with his tar and sludge goop being able to take an acidic and toxic property’s as negative emotions can be harmful and toxic.
But when he is interacting calmy with his allies he tries to maintain a more appealing version of himself which is closer to his canon design look, accept he sucks at it and just becomes a smaller version of his monstrous form (which would for be the same size of papyrus) but replace his sharp rows of teeth with an uncanny valley grin.
This is because Nightmare is basically an entity made of pure negativity and so struggles to create forms that everyone would universally be comfortable with and is one of his major weaknesses he struggles to understand why star sans try and help people they don’t even know. Hell, hes only been able to treat his faction kindly due to their situations which re-awakens how he was when he was passive and allows him to create bonds that he really shouldn’t logically be able to make as a being of negatively he shouldn’t be able to have good relationships within his faction.
The reasoning behind this more honestly edgy (Hopefully not cringey design) and disturbing design is I want to give Nightmare this feeling of being and looking like the final boss and give of the air that he is truly a nightmare that has come to life. While also showing how strange it is from an outsider perspective when you see this Lovecraftian horror have a positive reaction and interact with his subordinates.
This version of nightmare has a large range of powers and abilities like for example:
Being able to shape shifting into pretty much everything and sometimes even get some of their abilities but the goop tar like body gives him away always.
Acid and toxic goop which he can turn off or on.
Insane levels of Regeneration
High levels of Durability and Endurance outside of his regeneration.
Superhuman (Super monster?) levels of strength
Impressive reaction time.
Summoning horrific spawn or people’s biggest fears to fight for him
Powerful Anti-magic which affects his opponents the more negative they are ( Ink and dream are pretty much immune or have a high resistance to it).
The ability to create mass amounts of his goopy tar to containment the battlefield.
However, his biggest and most powerful ability is just how much of a biohazard he is to universes that he enters when he isn’t to contain his magic because as soon as he enters an AU his dark negativity and dark magic that he radiates will start to either kill, destroy the mental of people or horrifically mutate anything like turning plants into carnivores that will eat anything or poisoning the water so bad it kills everything inside of it and the worse part the damage is unfixable.
Now after reading of his powers, you may wonder why would he need subordinates if he is this busted? Well nightmare isn’t someone who fights in skirmishes like in most comics with the bad sans vs stars sans, he is in fact the win condition instead as he can’t enter au’s with a lot of positivity as the positivity creates a barrier in which he can’t get through physical( but he still can get to people in their mind and dreamscape) but he can if the conditions are right to teleport a certain group of people who would happily create enough negativity so he can enter the AU and contaminate it permanently. I think this also makes the bad sans like the MTT more of a threat and gives them more importance as its normally up to them if nightmare can’t do much with his mind manipulation.
Dream (our protagonist) and his magic like always is his kryptonite and truly the only one who can truly challenge but since Nightmare grew far more powerful after the apple incident, Dream is unable to undo his contamination, but he can fight to stop his rampage from hurting anyone else in the universe.
Nightmare being passive is also a major weakness to him as it makes him sometimes fail with going through with a kill shot that would of killed or hurt dream. He will sometimes even get distracted and points when certain situations make him relive an old memory.
His relationships (Subject to change)
( The descriptions may be lacking as I wish to develop deeper into the characters and their dynamics when I have time to write the story.)
Killer sans/ Something new sans-
Something new sans and nightmare sans is vastly different from their toxic dynamic in Canon Dreamtale and Canon Something new comic series, with them having a king and their right-hand man friendship or a another way to look at it a bromance between two sarcastic assholes who have a lot of issues between the two of them. Killer was the first person nightmare ever recruited into his group with their being two years between Killers recruitment and Dust recruitment who was the next to be recruited, this led to them developing a bond where killer is able to get away with things that most people wouldn't be able to get away with and in any situation where Nightmare doesn't know what's coming and needs to bring at least on person to back him up its always going to be killer.
Dust was the second person to be recruited by nightmare and this version of Dust sans quiet nature and Nightmares more serious and professional nature work really together. But they also struggle to communicate well with each other due to the distance that these two characters give each other as they refuse to stick their noses into each others business if they don't have too due to mutual respect for the other.
Horror was actually the hardest for Nightmare to recruit due to the fact that unlike Killer and Dust universe which is pretty much dead in the Lucidverse. Horror sans still had people he cared about and looked after Snowdin and so Nightmare would have to put so much effort into contacting and recruiting Horror as Nightmare is a walking biohazard and would have ruined the Au if he went their without any prep. They ended up creating an Alliance between the two of them with an agreement that Nightmare would offer help in Horrors Au while Horror would offer his assistance in Nightmares plans.
The two have a good relationship as Horror is able to help with planning team exercises due to Horror having make shift leadership experience and Nightmare being a pretty isolated person all his life and being an entity of negativity struggles with emotions and with the fact that Nightmare has way more people under him other than the murder time trio like versions of Asgore, Undyne, Papyrus, Flowery and Muffet.
Horrors and nightmare relationship can be best described as business relationship that turned to a close relationship that has a deep understanding of each other.
(I plan on posting my version of Dream and Nightmares backstory and their dynamic when I Have finalized both characters.)
