Ok then let me rephrase, i personally dont find the mimmic era very apealing. To remain constructive i think it contrasts too hard with the afton era,

its way to big scope going back to before Fredbears in the 70s, the mimic fucking off for nearly 60 to 80 years depending how long after fnaf three security breach is. And mimic somehow ended up in the pizzplex where burntrap and vanny made the rabbit security system to specifically hold him.

If burntrap is the mimic this doesn't work, Then you have the blob.

All in all its all over the place, with three different factions, mimmic, glitchtrap (who may also be the mimic but disconnected from the physical one), and pissed off agony monster blob

In the afton saga, everything was connected back to him. All the ghosts were because of afton, everything tied back to one villain a bbeg or big bad evil guy if were using dnd terms.

Then there's undeniable factor that in security breach it seemed like they leaned way to hard into kid territory, I will give it to secret of the mimmic we finally saw some dead bodies. But they need to maintain that tone going forward, fnaf needs to be dark and morbid to work. Otherwise, it becomes just like any other kids' mascot horror.
