You’re Past Gaster.

Dr. W.D Gaster.

Gaster was a skeleton, with an extremely close friendship with Asgore, that was until Gaster fell into the CORE.

Everyone forgot her, even her youngest son, Papyrus, but somehow, her oldest son, Sans remembered her.

It was 20 years later that something strange happened.

A portal opened up in a secluded area near Snowdin, in the UNDERGROUND.

Two humans had fallen, or rather, got thrown out forcefully.

The two kids had very weird looks, that no human should have, they looked almost more like monsters.

The girl looked like a skeleton, with two large holes in her hands, and the male looked more like a goat, just like King Asgore.

The interesting thing about the girl was that she had a distinctive bright red scarf around her neck.

When the two children stood up, Toriel, a goat-like lady, had came across the two, and was motherly.

Timeskip!

After Toriel and the two children introduced themselves, although Asgore had to introduce Gaster, as her language of Wingdings wasn’t understood by Toriel.

When Toriel walked to her home in the RUINS with Asgore and Gaster following in tow, and got there, the two kids saw someone.

A non-binary child named Frisk was at the table, eating some Butterscotch Pie Toriel made, but when they looked up, the child was stunned, clearly recognizing the two new children, despite the fact they were humans and kids.

Toriel turned to the two and spoke.

Toriel: ”Please, go in the living room and make yourselves comfortable, I’ll make you two a pie, you both must be starving!”

Toriel was… kind.

Meanwhile, Frisk was on the phone with Sans, telling him about seeing two children that looked strangely like Asgore and Gaster, but humans.

Meanwhile, Asgore and Gaster were in the living room, and Asgore spoke to Gaster.

Asgore: ”Miss Toriel is so nice!”

Gaster was reading a book, as she listened to her best friend speak.
