The Boggart.

The Boggart was created in 1993.
Molly Weasley's Boggart is her Dead family/friends. Her Boggart is mentioned in the novels, specifically, in 'Harry Potter and The Order of the Phoenix' I believe her Boggart was omitted from the movie.

His boggart is a banshee
A boggart is a shape-shifting creature that takes on the form of its intended victim's worst fear. It generally likes to hide in dark, enclosed places.In Harry Potter and the Prisoner of Azkaban, Professor Remus Lupin teaches his students in Defence Against the Dark Arts to approach a boggart in groups of two or more, so that the boggart will have difficulty in choosing which one to frighten. A common wizard's defense against a boggart is to point a wand at the boggart and say "Riddikulus" while thinking of something very funny; this charm puts out a protective shield so that the boggart can be held at bay, or manuevered away.

A boggart is a shape shifter. It lives in dark places and when confronted, changes into whatever the person fears most.
Lord Voldemort's boggart is his own dead body. His riddikulus is Harry drooping dead.
