Darkness (Fairly Odd Parents)

The Darkness is the main, later secondary antagonist of Wishology!, and its true intentions remain enigmatic until The Final Ending. Its sole purpose is to alleviate its lonely existence by making friends, but every planet it visits, such as Fairy World and Wonder World, the inhabitants have panicked by its presence, and they blast the Darkness back into space (the only exception was Yugopotamia, which was swallowed into the Darkness without any explanation why, although it may have intentionally did this to lure Timmy out to it).
