Undertale Multiverse

The universes crumbled in on themselves, vanishing in a familiar pop! However the skeleton did not waste time to admire his work; his time was running short.

Nemesis, the Greek goddess of revenge, loves to tear down the proud and mighty.

His rival appeared soon after, but he was already through his own portal. The shorter skeleton huffed and stomped his feet, annoyed that he still couldn't catch the source of the destruction.

There's a reason why things get more difficult as heroes and villains get better at what they do.

Said source didn't have the will or strength to fight. Instead he covered the parasitic things as best he could, and ran when he finished a job.

Flowers are some of the first plants to grow back after an area is ravaged by a natural disaster.

But that was weeks ago, and now the skeleton was forced to kill millions of strangers from the safety of his empty home. The place that was once his own personal hell.

So what better way to tear down Error, the broken and practically invincible Destroyer of AUs, then with the Flower Disease?

"Error! What the hell?!"

Error ignored the outraged cry that sounded behind him. Not that he could respond, even if he wanted to.

"Are you just going to ignore me?" the voice, which was undoubtedly Ink's, demanded. "First you go on a fricken' killing spree for weeks, and then I find you taking a f***ing nap?"

Even as the sound of footsteps moved from behind him to in front of him, all Error did was look tiredly at his old rival.

"Oh for the love of god, just say somethi-" Ink's outburst was immediately cut off when the Protector saw Error's face. "Oh," Ink said, his eye lights changing to show his alarm, "Oh my god."

The flowers, which formed an otherwise lovely-looking pattern on Error's skull, had sapped so much of his energy and strength that the only response he could muster was closing his eye sockets. The constant pain spiked as the flowers in his throat tried again to cut off his airflow. Error coughed, spitting out a few of the painful, golden petals as he lost feeling in his phalanges. All Ink could do was stare until he noticed the reason why.

Ink did not care about Error. He couldn't. But he did know at least one person who did.

In one swift movement, Ink created a portal to the small skeleton's living room, grabbed Error, and jumped through.

"BLUE!" he yelled, gently setting Error on the couch. Error was quickly losing his fingers and toes, turning into the same petals that were trying to kill him. "Blue, hurry!"

Blue frantically opened the door to his room. "INK?" he asked. "WHAT-" Ink carefully sat Error up so Blue could see him. Blue's bright-well, blue-eye lights dimmed considerably as they shrank from the size of quarters to tiny pinpricks. "Oh my stars-What happened? Where did you find him?" Blue asked Ink a flurry of questions as he ran down the stairs to his glitchy friend's side. Error managed no more than a hint of a smile at seeing him one last time, but Blue saw it. Ink shook his head helplessly. "He was in the Anti-Void. I don't know how long he's been like this, and I don't know how..." he trailed off, his meaning clear. How the hell had Error gotten the Hanahaki disease?

Error coughed again as more flowers bloomed on and in his body, pushing through his clothes to reveal just how many flowers were strangling him. FlowerFell Frisk never had anywhere near as many as Error had. Even though they had long since covered him completely save his skull, they had begun to crowd each other out, fighting each other for space as Error silently worked through the constant pain. Had...had he still been up and moving up till now? Even though they were more than enough to kill anyone else?

Tears formed in the corners of Blue's eyes as the thought came to him. "E-Error, why didn't you tell somebody?" he asked through his sniffles. Error shrugged weakly. His voice had been taken by the disease, and now it would take his life. Blue sobbed and hugged his friend. Prompted by Error's surprisingly clear, pointed gaze, Ink guided Error's arms so he could hug Blue back.

Even for the soulless artist, it was heartbreaking to watch Blue's reaction when, suddenly, Error was no longer there. His eye lights vanished, and the tears stopped as he caught a handful of the petals Error had become. Then, the shock wore off, and the sobbing began. The tears didn't come back; only a small flood. Papyrus, who had been at Muffet's, came in to find Ink doing his best to comfort Blue, as the stood by the couch in a pile of golden flower petals.

You're welcome, sweethearts.
