Kamille would eventually abandon the Mk. II (episode 21, "A Sign of Zeta") when the titular MSZ-006 Z Gundam, which Kamille helped design, is completed and delivered to the "Argama" (this also marks the first "mid-season upgrade" in the protagonist's mobile suit selection, which has since become a staple of the Gundam franchise). The Mk. II is then used by former Titans pilot Emma Sheen, who defected episodes earlier, before the Jaburo drop operation. Katz Kobayashi takes up operating the G-Defenser, and the two form a competent and effective team in utilizing the "Super Gundam".
