Contamination is a severely radioactive skeleton that resulted from a cataclysmic nuclear meltdown within the CORE, causing an explosion of universal proportions, all from an unwanted visitor tampering with it. Before transforming into the radio-monster that it is now, Contamination was actually one of the three scientists keeping the CORE under control and not having a potentially fatal meltdown, which it inevitably did.

## Backstory

* **Multiverse #000646052**
* **Universe ID: "Nucleartale"**
* **Timeline: Pre-Human**

Nucleartale, a Universe shaped quite similarly to the original Undertale Universe, but with a few notable changes. The CORE is now powered by nuclear energy, being watched by three scientists, each of whom take different shifts; Dr. Gaster, taking the morning shift. Dr. Alphys, taking the afternoon shift. Finally, Dr. Sans who, of course, took the night shift. On the eventual occasion that an emergency happens at the CORE, two of the scientists will hurriedly do as much as they can to prevent a potential nuclear meltdown, if their attempts were to fail, the remaining one shall quickly evacuate everyone from the underground, hoping to protect them from the very likely nuclear explosion. Now, our story begins with Sans preparing to head out for his night shift at the CORE, Papyrus suddenly appearing behind him just as he was about to open the door. "SANS, ARE YOU HEADING OFF TO THE CORE AGAIN?" Papyrus would ask his brother. "yeah, bro. gotta make sure the core doesn't blow us all to smithereens." Sans would respond, about to walk out the door. "SANS, AS MUCH AS I APPRECIATE THAT THIS JOB IS LITERALLY THE ONLY TIME YOU AREN'T A SLUMBERING BAG OF BONES, THIS JOB OF YOURS JUST SOUNDS VERY WORRYING TO ME. I MEAN, YOU'RE BASICALLY RISKING YOUR LIFE EVERY NIGHT BY HEADING UP TO THE CORE, POWERED BY NUCLEAR ENERGY! I HAVEN'T A SINGLE CLUE AS TO WHAT THAT IS, BUT IT SOUNDS INCREDIBLY DANGEROUS! EVEN FOR THE STANDARDS OF THE GREAT PAPYRUS!" Sans would begin to stop in his tracks as he heard his brother worrying his bones off about his truthfully dangerous job. "bro... i know full well that this job is dangerous and, quite frankly, could kill me one day, but somebody's gotta keep the core from exploding. sure, g and alphys are taking shifts at the core too, but even they aren't exempt from potential death, y'know? if the core were to, i don't know, uh, spring a radiation leak and i wasn't there to take the night shift, alphys would probably bite the dust- (ah, crap i made a poorly timed pun.) sorry. or, hell, probably even gaster for all i know. both of which are really good friends of your's, aren't they? look, the point being, i'm just doing all this for the safety of all the monsters in the underground." Papyrus would sigh, coming to a reluctant understanding. "FINE... JUST, PLEASE TRY AND BE CAREFUL UP THERE, OK SANS?" Sans, just before walking out the door for real this time, said one last thing to his brother before leaving. "will do, bro." With a wink, Sans was finally on his way to the CORE. After taking one of his famous 'shortcuts,' Sans had made it to the CORE in virtually no time at all. Once there, he would be met with Alphys, who was just about to head back to her lab after having completed her shift. "O-oh, hey Sans..! Y-you here for the night shift?" Alphys would ask the skeleton that stood before her. "yup, im just here to... nu-'clear' things up." Sans would turn ninety degrees, winking at apparently nothing while a drum beat played out of nowhere. "...Ahh god... Sans, w-we may be friends and all but... sometimes I just can't understand the things that you make happen. I-it's just, completely illogical." Alphys would nervously chuckle before making her way back to her lab, allowing Sans to make his way into the CORE. Once he had made it to the very center of the CORE, Sans would take a look at one of the gauges... ...it appeared to be at acceptable levels, leaving Sans to do whatever for half of an hour, which of course was to take a nap on the floor...

#### **Twenty Minutes Later**

While Sans was napping on the job, he would begin to experience something that would relate quite well to hallucinations. Within his closed bony eyelids, Sans would begin to see these strange dark yellow/bright red blobs. Though this wasn't like those occasional colored blobs that would occasionally float around in your eyesight while your eyes were closed, they felt a bit more... realistic. Sans would begin to open up his eyes to make sure he wasn't just seeing things... Not a thing in sight, only the nuclear reactor in the center of the CORE. Sans would begin to check his 'watch,' or rather a bunch of sharpie scribblings on his arm made to look like a wristwatch. "huh, still got ten more minutes to kill. may as well give the ol' gauges another check, give more time to rest, heh." Sans would get up off of the floor to go check back up with the nuclear reactor... ...It turns out that he wasn't alone anymore. From the distance, there looked to be a white-ish figure wearing a yellow sweater of some kind along with red pajama pants looking at the nuclear reactor from one of the CORE's metal platforms. From up a bit closer, *it looked almost exactly like Sans.* He could hear the mysterious intruder angrily muttering to himself as he gazed upon the reactor, something about Sans living a better life and having friends and family that treated him better? "hey, uh... i don't think you're supposed to be here, whoever you are. core's very dangerous, you could contract radiation poisoning or, uh... worse." Sans would call out to the figure, only to gain a turning of the head as a result. Once the figure had fully turned his head around to Sans, it appeared to be wearing a frighteningly furious expression. "you'd like that, wouldn't you..?" The figure responded, seething with rage. "...uh... yeah? it'd be real nice for the both of us." Sans would call back out, not having a single clue as to what this thing was talking about. "must feel real nice, huh? having a far more competent job than i ever could, having friends and family that don't treat you like a sack of shit for making ONE. *F̴U̷C̶K̴I̷N̷G̴.̴* ***M̷̞͎͇̭̩͈͉̜͚̙̗̬̻̞̬͇̖̑̇̀͌̀́̚̕Ì̶̤͙̭̺͈̦̯̗͈̥̥̲̄̈̓̽̀́̂͆̂̋͗̚͘̚̕͝S̵͎̭͓̘̮̠͚̣̖͕̱̔̑̈́T̷̬̳̦͉̩̤̪͒͘̕̕Ä̷̧͓̫̖̣͚̘̯̀́͗̄̃̆́́̾̓́̀̕͝ͅͅK̷̰͖̲͉̠͓̲̥̬͙̄̓͐͂̆̀͜E̷̯̣̭̳̤̩͐͛́̂̊̋ͅ.̴̨̢̧̪͈̭̬̞̰̘̙͓͆͑͌̎̅̂̓̇͒̒͝͝*** you must be livin' the dream, huh?" The figure would respond back before lightly chuckling, gradually increasing it's way into a full-blown hysterical laughing fit. "uh... look, i understand that you might be having some problems from what you've told me, but uh... maybe go somewhere else for some help? going to the one place in the underground powered by potentially extremely dangerous nuclear energy isn't exactly what i would call a therapy center, heh. so uh..." Sans would then wave his hand to the figure, hoping to get them out of the CORE safely. This would only generate another chuckle storm from the figure. "talk about ME getting help... heh... when i'm done with this place... ***Ń̴̢̩̮̘͐̓ͅO̶̖̐͆̈́̽̋̓͗͗͂̎͗̒͝ ̶̧̢̛͎̻͖͕̞͕̙̙̱͌͜ͅͅA̶̡̡̛̤̣̥̦̯̻̩̻͍̦̹̙͕͗̐͋̀͒͗ͅͅM̵̡͔͔̬̫̹͔̮̥͉̔̉̚͠O̴̡̜̥͖̲͚̙͂̉̂Ṷ̸̩̬̈́́̆͂̾̈̀̈́̓̓̚N̶̛͈̜͔͇͈̿̍̒̍̌̏͂͗̔̎͂̍̑͘͠T̴͙̯͍̈́́̍͗̉̈́̅͐̓̽̚͠ ̴̡̨̤̜̺͙̟̫̿͂̈́̊̊̋̆́͊̔͐͌̚Ó̸̡̦͖̳̬͎͙̼̬̘̘̩̤̙̓̅͐̉̂̾͝F̷̖͔̪̥̘̱͖͈͉̠̣̑̔̓̂͐̀̾̓̂̆͊̚̚ ̷̢̧̛̛̛͎̺̟̭̥̻̫̼̓̂̽̽̅͑̃́̿̌̊̓͝Ḩ̴̛̼͔̜͇̝̜̱͐Ë̶̠̳͔̹̝̮̗̬̳̗̜̩́̅̃̈́̾́̽̽̇̃͐́̎͌́̕͝L̵͍̰͔͓̲̥̋͋͌̓͛̉̋̿̾̌̌͘͘͝͝͝Ṕ̷̺̬̼̠́̋̅́̈́͒͆̓́̑̚̕͝ ̴̢̨̛̬̗̗̜̮̲̦͉̞͖̭̲͒̈́͆̍̎̊͌̐̽̋̆̚͝͝I̸̯̥̊̂̒̄̐̀̀̐̽̽̾̌̕Ń̸̨̤͍̣̄̉̀͑ ̴̨̡̖̱̪̣̫̪͉̟̩͓̔̇̂̑̃̀̄̾T̴̨̧̡̞̲̲̣͖̿̆̉́͝H̵̛̝̝̥́͒̆͛͋͊̿͐̂̐̆́̿̅Ě̴͉̭͂̌ ̷̮̺̥̗̞̙̭͕͙̯̑͊̀́͂̒̚Ḛ̷̓̿̈́̽͑̄̀͛̐̐̇̚͝͝N̵̺̫̗̳̻͙̉̋͌̄̊̒͋̽͗̉̀͒T̶̮̥̬̈́͑̎̍͂͛̕͠͝Ḯ̶̫̹̀̀̔̏̓̀̈͊̒̋̄́̍̚Ŗ̸̛͙̮͎͈̱̫̞̘͈͙̻͉͉̋̅̆͌͑̂͋̊͂̉́̆̐͛̓͘͜ͅĔ̷̛͖̦̥͔͈̙̥̯̪̦͉̞̲̀̆͋̐̍̏̌͘̕͠ ̵̩̠̪͚͖̞̪̞͎̠̦̗̋̑̓̏̋͂̅͌̿́͂́̓̊̕̚ͅM̵̖̾̂̽͝E̷̢̛̩͇͕̯̤̳̳̯̙̓̈́̏͛̌̒̎̅̅͘ͅŤ̵̖̳̌̑̍͂̉̐̀̕̚ͅͅA̵̼̹̻̼̤̼̍̏̽̓̿̈͗̒̓̉̉̆̚͜V̷̥̗͙̞͋̆̀̒̄̋̚͘͝͝Ē̸͎̭̖̮̰̖̼͌̓̂͆̑͐̍̓̉͊̈́͝͝R̵̨̯̺͖̬͙̈́̈́͂̊͂̅͝͝͠Ş̴̝̯̟̻̳̌̊̀̋̊̔̀̇͛̾̔͂͋̀͜͠͝͠Ȩ̷͍̬̠̹̞̜̠̝̬͇̥̦͓̝̱̰̄̉͛͂͛̅̇͂̈́̚͘̕ ̶̧̡̢̥̞̥̯͇̱͖̼̻̦͋̽͆́̿̔͠W̶̛̪͇̆̄́̈̀̈́͛͆͆̓̃͌̎͂͑̚Į̵̟̠̰̝̣͖̤̫̱̟̞̘͎̽̐̈́͊L̶̢̃̉́̈́̉̆͋̏̋̄̈́̚͘͝͠Ļ̶̟̰͈̜̻̤́̈́͒̄̄͐̏͑͂̃͗́̄͐̚͠͝ ̶̱͉͐̉̃͑͋͗̊̈́̏B̶̨̧̨̧͍̘̦̯̰̣̩̲̩͎̪̝̰̋̀͌̽E̸̬͒̇̑͘ ̸̢̢̡̛͕̞͇͉͇̖̳̙̭̝͕́͑͛̐̒͐̚Ä̷̛̠̖̘́̐͛̑̓̇́̉̾͠͠Ḃ̸̨̘̭̞͎͉͚̹̝̤̻͍̭̬̬̈́̾̉̃̆̒͑͋̾̉̎̅͜Ḽ̷̡̡̱͍̜̘͍̺͈̺̻̳̭͇̜͋̈̾̌̏͌̄̿́̈́͝E̵̡̻̞͇̫̪̞̙̟̪̤̗̰̎̆̿͊͑̉́͜͜͝ͅͅ ̶̢̩̩͈͈̣̺̠͕̲̮̹́ͅT̵̡̨͚͍̬̍͛̇̿̄̏̽͛̑̀̑͌Ȯ̷̢̢̻̱͇͉̻̼̠̩̬̙͚̓͆̅̍͐͗̕̚ ̴̧̡̬̳̼͉̭̱͇̼̝̙͈̻̲̫̈́"̷̡͚͕̩͔̲̟̜͉͖̻̙̾̀̀̍͋̈̿́̌̅̆͊̄̐̕̚H̶͇̫̝̘̘̖̙͇̰͙̻̦͚̥̺̄̽͂̀͆̄́̏͑̍́̋̊̚͜͝ͅE̵̡̛̞͙̣̪̮̳͖̜̐̔͋̆͑͊͗̎͝L̷̡̹̞̱̬̟̦̳̙̫͔̥̈́̓ͅP̷̺̩̻̿"̴̲͕̹͇̭̪̌̍͛̐̐̈́̎͊͗͒͐̊̕̚͠ͅ ̴̯̞̻͖͇͓̼̺̻̒̾̽̌̈̉̈́͐̽̉̔͐͌̂̚̕Ỳ̴̪̝̲̮͈̝͎͓̎͒̐̂͆͐̊̏̐͝ͅÓ̷̤͔̳̰̮̮̝͉͇͉̼̗̹̠͐̑Ư̶̧̯̘̂͆̉̊̂̾̋̔̾͝.̴̯̪̗̳̥́͌̄̈́͛͗͐́̈́̔̚.̴̧̢͙͙͖̯̲̗̜̺̦̪͑̏͆͒̕.̸̢̧͚͈̹̩̺̼̲̭͇͉͉͕͋͗̈̄̾͜***" Was the last thing the figure said before pulling out a massive, red trident glowing with yellow, slashing the nuclear reactor through it's center, causing a dangerous amount of yellow, noxious gases to leak from it. "SWEET MOTHER OF GOD, WHAT HAVE YOU DONE???" Poor Sans wasn't even able to finish that sentence before there was nothing but a bright, white light covering everything in sight, also feeling a hundred times more pain than he had felt in his entire life. The CORE had exploded and there was virtually nothing Sans could do about it...

#### **The Aftermath**

After a good three or four hours, the white light had finally died down, revealing to Sans nothing but what seemed to be nothing but a floor of dirt. Though, Sans was face-down when he saw this, this changed once he got up by using the last remaining bit of energy left inside of him. Once he lifted his face up, Sans could see a pile of yellow slime-like substance on the floor beneath him, also the fact that the dirt ground that he was lying upon was all that was left of his world. Not only that, but it seemed like this floating chunk of dirt covered in yellow goop was literally the only remaining thing in his Universe, even the Multiverse in this case. He also saw that the figure was still there, floating about in the vast remains of the space-time continuum, looking to be holding a hideously deformed yellow object, what looked quite similarly to... *his brother...* "so, i take it that this is your pathetic overprotective pussy of a brother? ...anyway, sibling or not, i'm takin' 'em with me... ***I̷̱̘̘͚̠͔̠̜̭̠͎̞͋͛̈́̿̉̔̀̓͆͒̐'̴̡̮̫͕̲̀̆̅̔̀͛̈́̈́̽̉̄̋̚͝M̶̢͕̖͇͎̅͌͑̉͑̆̔̈̾ ̷̢̛̤̙͈͈̼͔̈́̅͋͆̿̾͂̈́͘̚͜͝͝͝ͅͅG̶̲̭͎͕̜̣̞̈́͗̚Ȯ̶̳̠̦̏N̴̛͙̲̰̤̝͍̲͙͉̜̘̬͚̻̭̐̂̽̐͆̅͜N̷̛̝͚͉̩̠̫͓̞̼̽̔̐͌̏̄̀͝ͅǍ̸̧̢̫̟̩̬́̐̿̔̍̈́̓͛̆̋̒̀̇͘̕͠ ̸̺̖̘̬̀̅̅̒̾H̵̠̥̱̞̲̥̤̘̠̥̒̆̿̃̀͑͆A̶̧̛͔͚̺͇͒͐̎̓̓͒̍̕Ṿ̸̨̨̛̗͚̦̼̳̜̣͓̰̪̱̟̀̄̈̽͑̂́̐̀̌̽̚͝ͅE̵͔͙̣̜̖̦͖͍̭̪̹͖̮͛́̈́ ̶̘̥̟̣̭̯̹̪̘̥̩͔̙̺̔̽̏L̶̙͋O̸̡̡̺̯͖̠̼̝͔͔͙͎̺̭̮͊́̎̎͛ͅT̴̗̬̙̪͚͙͉̩̮͍̥̜̳̲̱̬̋̀̒̀̓́́͘͘͠ͅŞ̷̼̠̰͖̰̥̮̩̙̠͗̆̃̕ ̶͖̪͍̙͇͔͇̣͍͓́̔̆͊͜ͅO̸̗͐̋̅̐̃͑F̷̧̜̠̼̣̗̘̱͓̥͙̔̀ ̷̢̡̼̜͔̹̯͇̯̬̲͔̽̄́̐̄͐̋͛̀̈̀F̴̛̟̻Ų̶͇̲̳͖̥̲͙̩̝͇̥̦̇̊̓̉̈́̌̈́̈́̈́̀̃̊͒͘Ņ̷̫̯̣̲͉̫̼̬͙̩͖͔̳͈͙̈͆͌͗̂̅̇̚͜͝ ̶̨̧̡͖͈̤͖͖͓̬̗̟͆̍W̴̨͉̻̪̪͙̰̝̓̈́̏͐̃̂͝I̵͈̜̪̠̔̂̌͊̂͂̕̚͘͝T̴̯͍͖͎͑͂̏͆̋͊̑̎̅͌̈́̕͠H̴͎̾́̂͗͆̎͆͂̓͊͠ ̷͙̖̻̼̩͌̀̾͂̏̾́͒̆H̸̨̡̜̺̬̫̝̰̖͓̄̇͗̈̉̀̔́͋̽͋͗̐̅̈̚͝I̴̧̤̜̺̠̮̲͈̱̩̖̟̞͋͑̾̆̆̌̽͜͜ͅM̸͍̦͚̘̼̯͕̰̾͒̑͒̉̍̿̾̏̆̈́̈̉͜.̴̛̻̰̮̥͍̯̺̗̻͙̂̀̔̌͒͐̆͐̋̅́̚.̸̡̨̢̛̛̬͉̘͈̜̣̥̺̞̤͈̃̎͋͊̎̄̈́̓̍̀̈́̌͌.̸͙̌̅͐̽̾̊̋͋̃͊̚͝***" With that being said, the figure vanished along with the last remaining monster of Sans' entire multiverse apart from himself. Seeing the figure disappear with his only living brother in such horrible conditions, Sans would begin to slam his slimy, deformed fists down onto the dirt chunk beneath him in a fit of a mixture between rage and grief. He would begin to try and take one of his shortcuts in a desperate hope to get his brother back... it turns out that the nuclear explosion had hindered his ability to teleport. As it turns out, getting his brother back, much less his Multiverse, seemed grimly futile. Sans was doomed to float about on a barely stable chunk of dirt for the rest of his remaining days... ...until another figure tapped him on the back. Sans would look up to who had tapped him, the figure looked to be some sort of wounded, hooded monster with one giant, purple eye, wielding a crossbow, leaking blue blood from it's chest. It would begin to notion it's hand to come with it to a place of some sort...

## Appearance

Before the nuclear meltdown at the CORE, Contamination's work attire consisted of a long, black lab coat that has two white stripes near the top of it with a white t-shirt underneath, along with black sweatpants black boots that have white laces on them, as well as a yellow facial mask to protect him from accidentally ingesting any radioactive fumes while working with the reactor within the core along with heavily secured goggles that strapped on from on top of his skull and at the back as well. Prior to the events of the nuclear meltdown at the CORE, his skeletal structure now looks to be oddly textured and severly yellowed. Not only that, but his entire body looks to be leaking some sort of yellow substance from it, staining his white clothes by a very noticeable amount. His goggles may have been lost and/or destroyed in the explosion as he now has two very large scars running vertically through his eyes. Finally, his teeth have also been horribly disfigured from the meltdown.

## Abilities

### Bone and Gaster Blaster Magic

Though his ability to teleport has been lost in the nuclear explosion, Contamination still maintains his capabilities of using his bones and Gaster Blasters. Though instead of dishing out the KR effect, they now dish out an RD effect, which is essentially radiation. Getting hit with this effect will function much like KR, only it drains tens of thousands of times faster and WILL kill it's target if it reaches their HP to 1. Once the target is killed by this effect, they will disintegrate into a pile of yellow sludge, which will also dish out the effect if anybody were to step in the puddle corpse. This effect is permanent for any beings that are of High Multiversal power or below only, anything higher and the effect will only be temporary. The effect is completely useless against other radioactive beings.

### Toxic Substance

As mentioned several times throughout the article, Contamination is practically dripping with this substance, which is also incredibly dangerous to just about anything that it comes into contact with. It pretty much does the same as what the bones and blasters do, inflict the RD effect, only that it is far more potent if dished out from the sludge, specifically. As mentioned above, the sludge's effect is ineffective against radioactive beings, though it can only dish out one-tenths of harm towards them.

### Noxious Aura

Well, this isn't really more of an aura, more of highly toxic radiation emitting from Contamination. It pretty much functions the same way as the sludge does, only with half the potency.

## Trivia

* Though it seems highly unlikely to him, Contamination plans to get revenge on Animosity!Sans for destroying his Multiverse and kidnapping his terribly conditioned brother.
* Contamination is one of the astronomically few survivors of Animosity!Sans' Metaversal wrath.
* There are plenty more Multiverses containing the Nucleartale Universe, though none of them have met the same fate as this particular one did.
	+ This may be because of something potentially personal that Animosity had against that one Multiverse in particular.
