The universe of Creator/JossWhedon and MutantEnemy's ''Series/BuffyTheVampireSlayer'' and ''Series/{{Angel}}'' , some ''Spike'' comics, and in a later time period, the comic series ''ComicBook/{{Fray}}: Future Slayer'' (but apparently not ''Series/{{Firefly}}'', as it is set in a very different future from ''Fray'' - though it may simply be much, much later).

It has been given different names by fans: Slayerverse, Jossverse, and Whedonverse.
