- "You seem malnourished. Are you suffering from internal parasites?"
- ―John A. Zoidberg to Edna
- "Why, yes. Thanks for noticing."
Edna was a Decapodian woman who went to school with Zoidberg. She carried more eggs than any other female of her species: as such she wanted to mate with a rock star. She liked to talk about things of little importance at great length (much to the annoyance of those talking to her.) Her apartment is decorated like a fish tank.
Edna went to high school with Doctor Zoidberg and laughed at him because his face was covered in barnacles.
During the mating frenzy in 3001, she was courted by Zoidberg, however she rejected his advances claiming him to be an inferior specimen. Later, Zoidberg courted her again (while being coached on the art of seduction by Fry.) This time he impressed Edna and got her to go out to dinner with him. When a flattered Edna went to the restroom, she found out from Leela that Fry was behind the "romantic" words.
Subsequently, she falls in love with him and lures him to her apartment where she wears a blue teddy and tights to unsuccessfully try to seduce him, to his dismay. After she pins him down and kisses him, Zoidberg walked into the room and assumed she was "cheating" on him after seeing her with an unwilling Fry. Fry got free and tried to explain but Edna (while smothering a protesting Fry with her breasts) confirms Zoidberg's suspicion's by saying she and Fry have fallen in "love" with Fry and plans to mate with him the next day. Zoidberg, beyond angered, challenged Fry to Claw-Plach to settle the issue with Edna telling Fry they'll make love should he survive. Before the two finished their battle to the death, Edna and the Decapod Emperor left together and mated.
After the frenzy, due to the nature of Decapodian mating, Edna should have died, but during the unveiling of the final hole of Leo Wong's "Miniature" Golf Course, she makes an appearance in the stands and it is possible that she may have somehow survived. This is unverified, however. The fact that many older females are seen in the series, such as Zoidberg's mother, it implies that only the males die from the frenzy while the females become pregnant.
