Momoka Saotome is a physically strong and principled martial artist, raised in her family's dojo where she mastered disciplines like karate and judo. She consistently presents a polite and caring demeanor, demonstrating empathy and a strong aversion to bullying; she actively assists those in need and disdains flattery. Momoka maintains a long-standing rivalry with fellow pilot Jun Kirishima, frequently competing against her. Within the defense against the alien Draktors, Momoka serves as the co-pilot of the Megaton-class Rogue Maximus alongside Jun Kirishima. The Maximus specializes in ranged combat, utilizing missile pods for homing attacks, a role that necessitates Momoka's collaboration with Jun despite their rivalry.
