MASSIVE CREDITS TO THE GREAT AND INTELLIGENT EINESTEIN:

Tobyfox did not implement any Gaster files or references until the genocide Sans battle, which was at the very end of the game’s production. All proceeding creepy references are unanimously either to Chara or Flowey. Gaster has no continuity what-so-ever with the game before that point. Therefore, it seems that Tobyfox needed a reason to explain how Sans suddenly was ridiculously overpowered and understood time travel, and so Tobyfox developed Gaster haphazardly to explain it. Most of the appearances of him are mysterious and creepy in game in order to provide Tobyfox an outlet on which to add more content later if he wanted. Therefore, attempts to connect him with the main plot of the game are pointless.

The rest of their explanation is on here, and i believe it is something the wikia should know about :)
