If ya want Laney, she will either be Gaster's assistant, or an experiment donated to Gaster by her foster parents.

Experiment 3-L
Age- about 12
Sex- Female
Appearance- Gauze around her head with rainbow flaming eyes and star pupils that seeming to change color and shape with her emotions. She has pale skin and seems human, with short brown hair and rainbow highlights.

The subject will not speak or even look at the docter or other people when approached, huddled up in the corner of the room. Her eyes always resemble either pale blue or purple with tears drops for pupils. The subject will sometimes glow in golden light and seems to have a rare soul of gold, but the soul has a large cut down the center. Further tests must take place.

Docter Laney will be normal Laney, but a little motherly and and careful. She doesn't know what Gaster is doing with Sans and Papyrus, but when she finds out, she will be a little more sneaky in trying to save them.
