5 K-pop groups with ex-members

One of the common things that happens in the K-pop industry is that idol groups go through roster changes at certain points in their careers. The reasons for departure of a member or members range from a career change to a dispute with an agency. Usually only one to three members leave, but the next six K-pop groups have the most ex-members before disbanding.

Note: The list contains active / terminated idol groups.
