It is not a character. It shouldn't be treated as such. It is a concept created by Morrison, the Grand Master of metafictional BS in DC. Like I said before, if we would create a page only for it, it should be a concept page so that we can try to explain whatever Morrison intended when he came up with this idea.

That said, we already have a section that explains what the Overvoid means in the DC Universe as an entity, rather than a character. You can read it on the The 52 section of the Monitors article.
