"* Don't get me wrong, but those monsters used to be nice but something happened that will change everything. ""BeforeFell is a Backstory AU, its about how Underfell happened.
Asgore, Toriel, Asriel, and Chara
After Asriel born, he was very mean. Asgore and Toriel is always there to calm him down. After Chara fell to the underground, Asriel always bully Chara. Torie always calm Chara down after all of that bullying.
Years later, Chara decided to poison themselves ( Probably to free the monsters. ) Asriel absorbs their soul, and they came to the surface, Asriel and Chara died since they didn't fight back.
Asgore get mad after this incident, and he made a motto: " Killed or be killed. " he is much aggressive than before. Toriel decided to leave him, since she don't like the motto, and the plan to kill humans. Toriel tried to protect them, and she literally got insane after years and years of waiting for the 7th human.
Sans and Papyrus
Sans and Papyrus born with sharp teeth since there is not enough parts to make the whole teeth, Gaster decided to make them sharp. Aswell, Sans and Papyrus used to be nice to each other until one day, they got into the fight. The fight that will change their lives.
They both get aggressive to each other, and fight to each other. Sans get a hit on Papyrus eye, causing a scar on his eye. Sans made a mistake, and tried to apologize to Papyrus, Papyrus didn't forgive Sans for that since it wouldn't heal. After gaster fell to the void, he was being more aggressive to Sans and think of him as a pet, making him do his commands. Papyrus started to join the Royal guard after, Undyne was very impressed at him, and started to hire him. For now, Papyrus and Sans would change their looks to fit, Sans still regrets hurting Papyrus.
This is Gaster's experiments with the skelebros, it didn't end well.
ENTRY NUMBER 1 - THIS IS MY FIRST EXPERIMENT, I MADE ANOTHER SKELETON, THAT PROBABLY LOOKS LIKE ME. I ALSO MADE ANOTHER SKELETON WHICH IS MORE TALLER, AND HAVE MORE STAMINA THAN THE PREVIOUS, THE FIRST ONE I MADE IS SMARTER, BUT IT HAS LESS STAMINA, AND ITS SHORT. THE SECOND ONE HAVE LESS INTELLIGENCE, BUT THEY ARE VERY KIND. BECAUSE OF THEIR SHARP TEETH, I JUST... RAN OUT OF SKELETON PARTS. CUTTING MY HANDS TO MAKE HOLES ISN'T ENOUGH...
ENTRY NUMBER 2 - I DECIDED TO INJECT A BIT OF DETERMINATION TO THEM, BECAUSE IF THEY TRIPPED, OR HURT THEMSELVES, THEY WILL TURN TO DUST. IT WORKS FOR THEM. BUT THE FIRST ONE DON'T GAIN ANY HP, BUT DON'T WORRY, THEY ARE BOTH POWERFUL THAN THEMSELVES.
ENTRY NUMBER 3 - EVERYTHING IS FEELING FINE, THEY ALWAYS PLAY. AND EVERYTHING, THEY HELP ME DO ANY OF MY EXPERIMENTS.
ENTRY NUMBER 4 - SOMETHING HAPPENED, THEY BOTH FIGHT EACH OTHER MORE AGGRESSIVELY THAN THINGS. I TRIED TO MAKE THEM STOP, BUT THEY BOTH ATTACK ME FOR A BIT, AND KEEP ON FIGHTING. UNTIL THAT SKELETON HURT THE ANOTHER, HE TRIED TO APOLOGIZE, BUT HE PUSHED HIM AWAY. TELLING HIM THAT "IT WONT HEAL". THEY WALK AWAY, AND NEVER TALK TO EACH OTHER AGAIN.
ENTRY NUMBER 5 - I DID THE ANOTHER TEST TO THEM BOTH. I WILL SEE THEM SPAWNING THEIR ABILITIES. THEY BOTH SUCCESSFULLY PASS, AND I GAVE THEM BOTH, A STRONG ABILITY. I NEVER CALL IT YET. BUT I THINK I'LL CALL IT "GASTER BLASTERS", NAMED AFTER ME! ANYWAYS, THEY ALWAYS USE THIS ABILITY, AND ABUSE IT TO FIGHT PEOPLE. I JUST DISABLED THEIR POWERS AFTER THIS INCIDENT.
ENTRY NUMBER 6 - I MADE THE CORE, BUT ITS NOT FINISHED, ITS STILL ON PROGRESS. I MADE IT TO DO MY EXPERIMENTS... FAST. BUT I ALWAYS TRY TO FIND THE WAY TO COOL IT DOWN, SINCE EVERYTIME I TOUCH ANYTHING, ITS HOT. I ALWAYS WEAR COLD GLOVES.
ENTRY NUMBER 7 - WHY WONT THEY STOP FIGHTING?
ENTRY NUMBER 8 - OH NO, THE CORE... ITS OVERH- ( There is nothing, the writing stops there. )
As well, after this. All of the papers are ripped out, except for the 8 entries. There is a scribble in a clipboard that says " I STILL EXIST " everywhere.
