Gidget is the sensor and communications officer in Gekkostate. Her role is considered secondary and often she's featured relaying tactical data to crew or talking about relationship issues with Eureka.

Gidget is a bit of an airhead, which she admits, but she's not tactless and will go out of her way to protect others' feelings. She's in a relationship with Moondoggie, but only after she made the first move. Renton spotted the couple having their first intimate moment while hiding in an abandoned mine in episode 16.

About midway through the series, she tries to become friends with Eureka because she wants a sisterly relationship like the one Hilda and Talho have. After Renton left Gekkostate and Eureka realized he's gone, Gidget discovered Eureka taking on Renton's duties and even wearing Renton's sweatsuit given to him to pull off a prank for a laugh, but being the only thing he left behind, Eureka wore it in mourning. She is also one of the few crew members to have heart-to-heart conversations with Eureka, telling her that what she's going through was probably a change inside of her. Everyone found out later as Eureka told Renton and everyone eavesdropped on their conversation on the com-links. In another episode, she also went with Eureka to buy makeup since Eureka wanted to look pretty for Renton. In the end, Eureka tried to use the makeup by herself and ended up looking ridiculous. In the same episode, Gidget also says she couldn't live without makeup. Gidget is also shown to be fond of chocolate bars, and when she first talks with Eureka, she brings her a chocolate bar.

Gidget is based on a character of the same name who appeared originally as the title character of a novel and went on to be the subject of a number of movies and TV shows. The original Gidget was an airhead surfer girl thoroughly entrenched in beach life, much as Eureka Seven's Gidget is an airhead refboarder thoroughly entrenched in lifting culture.
