Seriously, I think it's a paradox.

You said that Frisk arrived in the world of Undertale WITH the monster disguise, to investigate the anomaly.

Beta Frisk is just a past version of Frisk, the version that Sans encounters. So they should be retracing Alpha Frisk's steps, until a difference arises between the two timelines-In that case, they can and will do different things in response.

To calculate what Beta Frisk's actions SHOULD be, we ask ourselves:What would Alpha Frisk do if they found themselves in this situation? They're the same person, after all.

And this is why the two timelines are incompatible.

I'm not going to call an event a glitch. It's not a problem with the game, it's a problem specifically with your theory. The answer to why we don't see Frisk with a monster disguise is simple-They never put one on to begin with.

By the way, the DT extraction machine's status was inactive. It was never activated yet. Perhaps Gaster was not conducting DT experiments in 201X, but was merely preparing for them, for when a human (eg:Chara, Patience Human, Bravery Human, etc) would fall. Do you have evidence that Gaster was still specifically making DT experiments this early on, rather than Sans simply killing him before they began in the first place?

...Because if Gaster now did fall before the DT experiments even began, there is no longer evidence suggesting Chara wasn't the first human.

While I can't think of anything more horrible, I can think of something that has more evidence to support it:Deltarune, like the secret images I linked in Round 5 suggest.
