The Blorg became something of an inside joke within the game. Due to fan requests, the empire was included in the game at launch, together with the Fanatic Befrienders AI personality, unique only to the Blorg and any empire with the exact same ethics and traits.
The Blorg Commonality was a fanatic xenophile misunderstood empire that desperately wanted to make friends, and also had a militarist side in order to force others to be their friends if everyone rejected them. During the pre-release stream series former Stellaris game director Wiz was inspired by one of the fungoid portraits to create a very friendly but hideously ugly species called the Blorg.
