Marsha Rizarov holds the position of second-in-command within DICE F-99, a specialized rescue unit operating across the Sarbylion galaxy. F-99 is distinguished as DICE's sole unit comprised entirely of children. At fourteen years old, she serves directly under the unit's fifteen-year-old captain, Tak Carter. Her teammates regard her as an older sister figure. Marsha possesses striking green eyes and vibrant red hair. She utilizes the RADOC system to summon her Gild suit, enabling her to "guild up" for missions alongside similarly equipped teammates. Unlike several other core F-99 operatives, Marsha does not pilot or operate a personal Dinobreaker transforming vehicle. Narrative elements in Episode 8 hint at romantic feelings between Marsha and Tak Carter. Throughout the documented missions involving the team, her responsibilities and role within the F-99 unit remain consistent.
