Extraordinary Confusion.

By being in the middle of the two oceans, they have jumped out of them temporarily. But it was not by their own power, so they can't destroy any copy here. 

They can't even fly higher to reach the cubes above them. They are stuck in their current position and cannot move about.

Not that it would be of much use even if they could move and destroy a copy, because they will need to find the true body of the copy they destroyed and kill that too. Preferably before another copy is created. 

The clones stopped thinking about that and looked around to see if there was anyone not submerged in the void universe. The only ones they saw were them and the creator of the void universe itself. 

The creator and progenitor of every being in the void universe looked like an indescribable entity. At least, it looked indescribable to them. They were struggling to understand what it was that they were looking at.
