Michiru Saotome appears across multiple iterations of the Getter Robo franchise, with significant variations in her role, background, and fate. In the original 1974 anime television series, she is the daughter of Dr. Saotome and sister to Tatsuhito Saotome. Witnessing Tatsuhito's death during a prototype Getter Robo test attacked by the Dinosaur Empire draws her into the conflict. She pilots the non-combining support aircraft Command Machine (later renamed Lady Command), resupplying the Getter Robo and deploying explosives or supplies during battles. Demonstrating strong will and courage, she volunteers for a suicide mission against the ultimate Mechasaurus, though Musashi Tomoe takes her place and sacrifices himself. After Musashi's death, she temporarily pilots the Getter Liger when Hayato Jin is unavailable. Her friendly, polite personality earns her the nickname "Madonna of Asama High" among peers. She shares a close bond with Hayato, partly due to their mutual experience of losing their mothers. In the manga continuity (Getter Robo, Getter Robo G, Shin Getter Robo), her role is reduced. She is Dr. Saotome's middle child, primarily depicted in domestic or supportive contexts without combat involvement. She interacts with the Getter Team as friends, showing concern during crises—such as when Ryoma Nagare suffers amnesia or when she protects him from missiles, sustaining injuries. Her personality includes moments of assertiveness, notably confronting her father after he kills her brother Tatsuhito, who was controlled by newts. She attends social events with the team but retreats to safety during invasions. Her story concludes during the events of Shin Getter Robo, where Getter Ray exposure from the Shin Getter Robo's activation kills her and most staff members. In the OVA *Getter Robo Armageddon*, her backstory is reimagined. She dies prior to the series' events in a Getter Robo combining accident involving Ryoma and Hayato. Her death fuels Dr. Saotome's vendetta against the Getter Team and motivates his alliance with the Invaders to destroy humanity. This incarnation establishes her as the older sister of Genki Saotome, who later assumes the identity Kei Kuruma after trauma-induced amnesia. Other adaptations feature divergent portrayals. In *New Getter Robo*, she is depicted as older and more focused on studying the Oni than combat, exhibiting a shorter temper compared to earlier versions. Video games like *Getter Robo: Daikessen!* list her as a playable pilot with reconnaissance abilities, though narrative details are minimal.
