Sky Pirates!

Now Yani watched the solid shadow of the Big Eating Thing - a form that she could only see hints of but, she knew, the others could not see at all - as it tore at the Magic Man, blasting him with alien energies and burning him up, peeling him back layer by layer.

And Yani saw, in a direction that the others would have never seen, that each time a layer was torn from the Magic Man he was getting bigger.

It directed another burst of energy at the Magic Man - burning away the thin and human-seeming figure that existed on the physical plane - and the Magic Man replaced it with what Yani thought of as his "other body". The body that nobody but she, and Kai, and the others of her people had been able to see.

And the thing that was in the quasi-space was vast now. Bigger than the sun.

Every time the thing inside had burned the hated thing away, the hated thing had merely got bigger. The thing inside couldn't understand it. It was as though a series of fleshy masks had been burned away, one after another, exposing the larger mass enfolded within to at last reveal the massive skull beneath the skin: the horror at the core.

And in dimensions and directions that only the thing inside could see, the hated thing was vast, now, impossibly powerful. It could crush the thing inside with the merest flicker of an idle thought.
