Martha Shobeypower, alternatively spelled Martha Shoebbeypower, serves as a Reasoner at Basion Academy and belongs to the student combat unit, the Space Squadron. She maintains a consistently close bond with fellow squadron member Ermengarde Johannitz, frequently appearing alongside her during activities.

Martha possesses a notably masculine presentation, often making immediate identification as female difficult. This visual aspect contributes to her interpretation within a butch lesbian archetype, particularly in her dynamic with Ermengarde. She demonstrates pronounced enthusiasm for physical training and muscle development, regularly engaging in strength-building exercises. Her dietary preferences strongly favor meat consumption, contrasting Ermengarde's health-conscious habits.

Within the Space Squadron, Martha operates as a combat pilot, commanding advanced mechanized units called Strains. She integrates into the team alongside members Lottie Gelh, Jessie Ijesse, Dickon Cidnok, Carrisford Radofrics, Ermengarde Johannitz, and Lavinia Reberth. This collective, led by Lottie, initially faces teamwork challenges but gradually evolves into a more unified fighting force.

Official media, including potential supplementary materials like movies, OVAs, or spin-offs, does not elaborate on her character background or developmental trajectory. Information remains focused on her established role and interactions during the primary Basion Academy storyline.
