Gaster in MHA

Within a container of darkness, lived a lonely man. He was mentally unstable and physically weak in his state. One day however, there was a bright light that brought him into a 'different' place. One that didn't hold monsters such as his first home, but humans. Humans that had powers. I don't own any character, this is just a fan-fic. Also I don't own the cover either, just found it off the internet.
