Which fictional character, other than monsters, was in the most movies?

Charlie Chan wasn't truly a fictional character.

Chan's creator, author Earl Derr Biggers, patterned him after a real-life detective in Honolulu named Chang Apana that he read about in the newspaper in 1919.

Can someone please tell me how many movies Santa Claus was in?
