To be honest, I have imagine my OC being a guy and being all gay with Gaster AU... So there is a tease! 😜

Ok so to tell you a little story about what happen. Rose went to Alphys lab to help her with a experimentation. However, one of the substance explode right in front of Rose. Alphys call Gaster to tell him about the accident but didn't manage to tell more as he was already there to see Rose. When he saw her... She became a he! Problem with Male! Rose is that he was a flirt and a teaser which is the complet opposite of Rose. Rose is more shy and reserve. Most of the time, it was Gaster that make the first move. So the scene is more like Male!Rose teasing and flirting with Gaster when on the other hand didn't like it that much, but he cannot punch him cause that would be mean to punch Rose.

There ya go my first drawing! 😄

FYI! This Fell!Gaster is own by Bunnymuse! Her Gasters are great ya all should check her out at her deviantart!
