A depiction of Universe Iteration Y5G-58, 2029 A.D.
A couple hundred years ago, it was taken over by the aformentioned GOMER GIMPSON, when some scientist fellows decided to experiment with several Simpsons vhs tapes. The tapes were being subjected to some thamaturgical stuff before it accidentally transformed it into a blob-like mass with Homer's face on it. The blob assimilated the entire facility, turning it into a neon-yellow structure with Homer's giant face on it.
Afterwards, it took over the surrounding neighborhood, and then the North American Continent. It spilled into the ocean, converting the water into liquid Homer, and transfiguring all the fish into homer-fish. A year later, the whole world was converted, now a giant yellow meatball with homer's face on it (you can actually see it in the sky in the provided image).
Bored, the now lonely Gomer Gimpson began exuding Homer-Oxygen from its massive pores and traveled to the other planets. It assimilated Mars, then Jupiter, then 98% of the Asteroid Belt, you get the picture. Over the next 286 years, it traveled from extraterrestrial planet to another, absorbing the knowledge of whatever organism it could find on them. Eventually it learned to somehow make its own dimension after an encounter with a particularly intelligent species of amphibious space-shrimp.
Now here we are, Gomer's 800,000,000,000,000,000,000 children that used to be humans, animals, aliens frolicking around the yellow masses that used to be planets and asteroids.
