Not sure if this is the board/thread I would post this, but I had this intrusive thought while trying to fall asleep last night about an eldritch being that was born when the universe was young;
it consumes and consumes for its endless lifespan, eventually growing in size to that of planets, stars, galaxies, nebulas, consuming everything in the universe. But it's not satisfied. It consumes all of the galaxies in the universe, until it surpasses the size of the universe itself and eats it from the inside-out. Free from it's boundaries, it moves on to consume other universes in the infinite multiverse with one effortless gulp, forever growing for all eternity.

Is there a being in fiction already similar to this?
