Everything dissolved into darkness...

Everything that Mettaton had, the love and joy of fans, fame, ratings... everything sank into a big abyss, which is unlikely to return everything he lost.

After the monsters were imprisoned underground, they adapted to a cozy carefree life, magical food, good air and stars appeared, all thanks to the CORE, as they call the reactor, which processes magic into useful substances for the Dungeon. Later, Asgore wanted to get to the surface so much that he wanted to use this reactor to break the Barrier, which led to a huge explosion that affected most locations, and Snowdin became a special victim of the explosion, many residents died, and some managed to escape, Asgore banned the use of water in the Water Zone, because of which most zones sank in fire. Alphys helped Asgore make a camp for survivors, but there was terrible hunger and thirst. Toriel starved herself to feed Chara and Asriel, believing Asgore to be a selfish and short-sighted idiot, then slowly managed to restore the reactor, but the attempt failed, causing even more massive explosions.

Asgore fell into despair, the final straw was when Toriel went mad from the weight of all the problems and hunger and ate Asriel. The king locked himself in the throne room and did not come out, leaving Alphys to deal with herself. Undyne, appointed as the general of the guard, led the MRA army, destroying everyone who still served Asgore and tried to take revenge on him, but she was eventually injured and banished. This only increased the death toll, and Undyne achieved nothing.

Mettaton, who had returned to Alphys's lab after a light walk, was still looking for her with a kalpa of hope, believing that everything was fine and as long as he was with her, there was a way out "Alphys! My dear! I think we need to...-" He was interrupted when he opened the iron door. Alphys's lifeless body was hanging on a rope. She had committed suicide, leaving him alone in this hell...

That's it... he didn't know what to do... how could she leave him?.. how... she left him here to rot alone - he thought, sitting on a chair and looking at this horror

A couple of days later, the Monsters had lived to such horror that they had gone mad and now mutated from cute monsters into horrible hungry mutants, only a few people remained alive.

Mettaton locked himself in the Lab, now doing nothing, just sitting and looking at the turned off computer panel, like a lost puppy. he had lost the last sparks of hope and was now just waiting for a terrible fate to befall him or for his body to finally lose its strength and he would pass out, and his steel would slowly become covered with moss and rust..

when suddenly he heard the faint scraping sound of the door to the Laboratory opening

" ah?.."

he didn't know whether to react to it or not
