Ongulian is the home planet of the Ongulians.
It was destroyed by Id, the Selfish Moon, with almost all the inhabitants, with the exception of the crew of the Command Ship of the Ongulian Defense Fleet, led by the Commander Kak who swore revenge on Id.
Those were saved from the planet explosion wave by Id itself, as Id sniffed all the planet dust to enjoy Idself. There is now no proof of precedent existence of Ongulia, except for the remaining Ongulians of the Defense Fleet.
The Ongulians eventually avenge their planet and families, six years later, with the help of Deadpool.
