Although she may look a good person on certain occasions, in other she reveals a hypocritical woman, gossipy and sometimes seed of discord. She often behaves in an arrogant way, and she is also provocative against Marge, in fact it contributes to her conviction for shoplifting, with a false slander. But often, she is confined only to tease her.
An another example of the rivalry between Marge and Helen appears in the episode "Ned 'N' Edna's Blend", when Marge organizes a party and Helen is not happy to be going well, Ned discovers that his children have changed, and he doesn't like what Edna has done, Marge tries to save the party, but she says to her that it is too late and so she photographs the party ruined and sends it over the phone.
She is voiced by Maggie Roswell.
