Id the Selfish Moon is a villain in the Marvel Universe and an enemy towards Deadpool.
Id was born in the Black Galaxy in the shadows of Ego the Living Planet. Ego attempted to keep its existence a secret from the Rigellians and other sentient races. Id, however, wanted to be known and party. Id found the seclusion of the Black Galaxy to be boring, so Id decided to traversed galaxy after galaxy to find something more exciting, but was unsuccessful in finding the excitement that it sought.
Eventually, Id came to the realization that other than Ego, there were no other beings in the universe like them and Id began to despise those that could experience companionship, partying and fun. These feeling caused Id to go through a form of dementia, and Id continued on its quest of revelry and happiness only now it was fixated on destroying them. The first planet to be destroyed by Id was Kegger 24-7. Id used his seismic waves to cause catastrophic force that reduced the planet and its inhabitants to space dust; many more planets followed this horrific fate.
