Gaster Blaster Sans X Reader

Part 34

"S-Sans! Calm down!" Alphys yells.

Too late. Sans is already transforming into the Gaster Blaster Beast.

You decide to try and call Alphys to see what happened to Sans.

(Back in Alphys's lab)

Alphys left Sans in the machine overnight. She shut it off, but didn't let him out. Alphys went back in to check on Sans, only to find him still blasting the inside of the machine. Alphys cautiously went over to the control panel. Her jacket pocket starts to buzz and ring. Sans stares directly at Alphys. Alphys slowly gets out her phone and sees that you are calling her.

"H-hey, y-y/n" Alphys answers the phone nervously. Sans tilts his head.

"Finally. I've been trying to text you for two weeks! I finally decided to call and-" you say, but Alphys shushes you. You stop talking wondering what's going on.

(At the same time in your house)

"I'm p-putting you on s-speakerphone. Sans is h-here in his full G-Gaster Blaster form" Alphys explains to you.

"Is he alright?" You ask, pacing around your room. There is a long pause. You stop pacing, waiting for a response.

"I-I'm not sure why, b-but he's been really u-upset. I don't think he s-slept last night. H-he went into the m-machine yesterday, and s-something went wrong. He's been r-raging ever since" Alphys finally says "He's kind of c-calm now. I think . . . Maybe it's b-because he can hear y-you."

You hum and start to pace your room again. "Sans? Can you really hear me?" You ask. You pull your phone away from your ear as Sans gives a loud bark. Alphys screams, startled.
