Cosmo Kramer was a native of the Sitcom Multiverse, although he could sometimes be spotted in others. He wasn't very prominent in that multiverse, just a regular, ordinary fellow, apart from his unusual mannerisms and behaviour.
He was friends and neighbours with Jerry Seinfeld, a comedian who was at the same time often annoyed and yet caring for Kramer. He was also friends with George Costanza, and Elaine Benes. He was also friends with Newman, Seinfeld's arch-nemesis.
Researchers have noted his resemblance to Eugene Sleighbough, among others.
