Specification: Thought I might leave this here so you all understand this post better, these images are all taken from different media sources, and different canon's, the joke is, is that across these platforms when it comes to level 0 there are many inconsistencies, even though, by popular opinion, there is no entity 0 or entities in level 0 naturally.
Further Specification for your insane people out there: The first image is a reference to kane pixels cannon, which is its own monster altogether. The second image is from another cannon where the entity looks different altogether. And the third and final image is from the standard cannon in which there is no entity 0 altogether, the joke being that there is little to no consistency/agreements regarding this topic across the expanded universe on platforms like youtube.
