The term guest appearance generally denotes the appearance of a guest in an artistic or pop-culture setting.[1]
The guests themselves (referred to as guest artists,[2] featured artists,[3] guest stars,[4] or guest fighters,[5] depending on context), are distinguished from the other real artists or fictional characters by not being part of or fitting the usual theme of the cast. They are usually recognisable on their own and only appear once or rarely within that cast.[6]
