Idea #35 (Reality Warping to Amalgam)

This is a story based off of anything you want. The premise is that a small child of our world gets reality warping powers and pulls a Saiki K situation (if you don't know know Saiki K, he is an esper that made everyone in the world believe that different colored hair was normal and forced people to start naturally getting green, blue, etc. hair colors).

The main character starts to bring all of the things they love to earth without regard for consequence making a full amalgam universe on regular earth. It depends on you what you want those consist of, and how you build your universe after the bringing together of all these different concepts. The main character loses their power after doing so because they have toyed with reality too much and the beings they have brought over have the ability to seal their power or permanently delete it.

It then can go in any way that you want.
