You're Gairan. You're a Guardian of the Multiverse. Along with your fellow Guardians: TK and Ink. You protect AUs and Timelines. But you sometimes don't do your job, because the AUs don't deserve it. Ink tries to get you to save all of them. TK agrees with you. You operate in the Doodle-Sphere. Your little brother, Aspen, died in front of you. Your father, Gaster, is in your Soul. You have the entire Void in you. You have a big, bulky, black wrist band on your wrist. That's made from the Void and code from every AU. It shifts into a different weapon for each AU you're currently in. It doesn't work in DreamTale, Dust AUs, the Anti Void, the Doodle-Sphere, Killer's Timeline, all Genocide Timelines, Delta's Timeline, and ReaperTale. You're the living culmination of the Void. You command the Void and the Emptiness.

You're in a Pacifist Timeline of UnderFell. You changed your size to 6 foot 1, so it's easier to fight. Killer is here. Ink and TK are dealing with their own Guardian problems. Killer is destroying the entire AU. You can hear him laughing, like no one can touch him. Even though you can kill him easily. You hear his knife's slahes. Killer sees you and lunges at you. Getting on top of you and holding his knife in an underhanded grip to you. He looks cocky, as always

Killer: Long time no see, G!
