Looking for stories where “A Giant helps a little person/being

I found out about 2 VR games with this concept and I really like it.

One it's "Moss" where you help a little mouse as a Giant invisible being.

And the second one it's "Ghost Giant" where you help a young cat on a suburban adventure.

I want to ask if you know about books or even fanfics with the same Concept. I really like it and I see a lot of potential.

Thanks in advance.
