Edna was a half-Japanese, half-German, short fashion designer and auteur. She was known for calling everyone "Dahling" ("darling").
Edna had created custom-made original outfits for superheroes since the "glory days", saying that she used to design for gods. It was apparent that she felt infinitely superior to all other designers in the world and showed much disregard toward runway boutiques and modern fashion models, claiming that she had gone to Milan to design clothing for the supermodels, and called them "spoiled, stupid little stick-figures with poofy lips who think only about themselves".
Edna was called out of a 15-year period of imposed retirement to repair damage to Bob's supersuit, and ended up producing a series of completely new, matching outfits for the entire Parr family. For safety reasons, she was very insistent on not including capes in the new design, mainly because any superhero who had a cape ended up killed or trapped.
Later, when Bob's wife Helen discovers that a rip of his super-suit had been mended, she suspected Edna. She contacted Edna, wanting to talk about the suit, and Edna insisted that she come see her almost immediately. Helen went to Edna's mansion, where Edna revealed that she had designed super-suits for the entire family, adding that each suit is equipped with a homing device. As Helen desperately wanted to find out her husband's whereabouts, Edna handed her a device that gave her his exact location. When Helen found out that Bob was on a faraway island, she broke down in tears, in fear that she was losing the man she loved. Edna then whacked Helen on her head with a newspaper, demanding that she pull herself together, go confront the troubles he is facing, fight, and win, now that she knew where he is.
