After its capture by Mars Zeon, the F90 Gundam F90 Unit 2 was extensively modified. More than 80% of the mobile suit's exterior has been replaced, and the modifications were done with the aim of making it compatible with the maintenance/spare parts owned by the Mars Independent Zeon Forces and priority was given to parts with high wear and tear rates, such as the drive unit and exterior. In addition to the spike armor on the left shoulder and the exposed power pipe around the collar, which were meant to make it look more like a Zeon MS, the sensors have been enlarged and apogee motors have been added.

The Gundam F90 Unit 2 was captured by the Mars Zeon near Side 4 and then modified using the parts they have and repainted in a distinctive red-orange-white color scheme. The Federation's 13th Autonomous Fleet was subsequently sent to destroy Mars Zeon and recapture Unit 2. During the fight in the Mars Zeon's base, the modified Unit 2 piloted by Bosch battled against the Gundam F90 Unit 1 piloted by Def Stallion. Both units were heavily damaged, but in a final move reminiscent of the final battle between the RX-78-2 Gundam and the MSN-02 Zeong, Unit 1 emerged victorious.
