Barb is a spider that is first introduced in "Web Weirdos." She is married to Ed. She was upset with Ed because he thought it was gross when she spins webs, and he insisted that she spin one. Ed tried to give her a Glowing sword as a gift because of Finn's advice, but she thought he got it for himself. They got into a fight in which Barb tried to eat Ed. She was succeeding until Finn saved Ed. Barb then went into contractions, and she gave birth to thousands of Baby Spiders. She and Ed then made up.
Barb is a giant spider, slightly taller than Ed but about the same size otherwise. She has a black body with three round segments and a sucked-in grey face. Her eyes are black circles with white bits that make them shine, giving her a feminine look. Like Ed, she has eight legs with two attached to her head segment and the other six on her thorax. The two legs on her head act as her arms rather than legs.
- When Barb tried to eat Ed, it is similar to what actual spiders do in real life. The female often consumes the male when mating.
