Earth-1218, sometimes called Earth Prime is the designation given by A.R.M.O.R. to our world, the real, non-fictional keystone world in which Marvel Comics is a comic book company that publishes books featuring the stories and characters referenced on this wiki.
Our universe is the true, keystone Earth from which all the other Earths within the Marvel multiverse originate from.
- In the final episode of Spider-Man: The Animated Series, after saving the multiverse from Spider-Carnage, an evil version of himself from an alternate Earth, Spider-Man briefly visits a animated version of Earth-1218 and meets his own creator, Stan Lee.
- In Indestructable Hulk (Volume 1) #3 , it is revealed that 4 years of comics published on Earth-1218 is equivalent to 1 year on Earth-616. This would mean that only 13 years have passed in Earth-616 as of 2016, counting from Fantastic Four (Volume 1) #1's publication in 1961.
