Reality Warping

[Sniper670]

"I can do anything and I can be anything".

It's about reality warping. I want to find a way to get it useful outside of what is shown. So here's my question. It's just one

Can a character be able to do anything related to what he's been demonstrated to do?

Here's the example
Character A turns people into books.

With this in mind, can we assume he can turn people into various other related objects? Pens, table, vase etc

Or Character B turns a human into a dog
Can we say he can also turn them into horses, cats, goats, etc?

Case by case depends on how deep and far the cosmology goes.

Case by case depending on how the Reality Warping works, if he is said to be able to change anything into another biological form, then example B doesn't matter

And conversely if his Reality Warping has limitations with one specific form, then example B will not work
