List of multiple character changes

In BFDI and BFDIA, but mostly BFB, characters will occasionally change their appearance throughout all or part of the show. Although these changes are often temporary and are changed back to normal, usually after a character’s death and recovery, there are other times when the changes are permanent. It is assumed that original appearances of the characters who have changed will return once they die, though there are some instances where this was not the case.

In order for a change to count, it must be a noticeable physical change, and it must span over more than one episode.
