So like Pearl said in Fusion Cuisine, their physical bodies are constructs meant to mimic human physiology. So I'm wondering, what if the monsters they fight are based on alien races? That is to say, we know there are other gem-occupied worlds, and it's reasonable to assume that the gems on those worlds act as guardians in the same way GAP do.

In Cookie Cat, you'll remember that they knew the creatures in Steven's house were called "centipeetles" and that they had "a mother". Which leads me to believe there are more centipeetles in existence than that one corrupted gem. So basically the Mother that Steven befriended would have been the gem that once guarded the planet that centipeetles live on, and this would also be true of each monster they've fought, representing a race they once protected before becoming corrupted.

Just a theory, and it pretty much stems solely from the fact that their wording in Cookie Cat sort of implies there are more centipeetles in existence than that one corrupted gem.
