"A Hero for Halloween" is the Halloween episode of the Disney Channel animated series The Proud Family. It originally aired in the United States on October 18, 2002.
It is Halloween in Wizville, and everybody seems to be in the spirit, except for Penny Proud. When Penny is forced to don a costume to serve Proud Snacks to trick-or-treaters, and then is sent off to a Halloween party she cannot get into, she casually takes a bite of her father's snacks and develops superpowers. This happens just in time, since she has to thwart a major crime spree by the Gross Sisters and protect her family from the wrath of a miserable ghost.
