Technology & Combat Characteristics

After its capture by Mars Zeon, the F90 Gundam F90 Unit 2 was extensively modified into the OMS-90R. 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 Mars Zeon, 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.

Although the most prominent feature of the original Gundam F90, the ability to mount the Mission Packs, has been removed, Mars Zeon installed a different hardpoint system as they plan on equipping the mobile suit with new optional equipment. Notably, the forearms are now equipped with connection mounts capable of supplying huge amount of energy, and one theory is that this is for the equipping of beam shields. Other parts of the mobile suit such as its basic avionics system and the pseudo-personality computer remain untouched, and so its performance is mostly unchanged. However, the Gundam's mobility is slightly lowered due to being heavier, but it has improved defensive power in close combat and this resulted in the mobile suit's individual performance being enhanced.

History

In U.C. 0120, the F90 Gundam F90 Unit 2 was captured by Mars Zeon near Side 4 and then modified using the parts they have and repainted in a distinctive red-orange-white color scheme, resulting in the OMS-90R Gundam F90 (Mars Independent Zeon Forces Type). The Earth Federation Forces's 13th Autonomous Fleet was subsequently sent to destroy Mars Zeon and capture the Gundam F90 (Mars Independent Zeon Forces Type). Later, during the fight in the Mars Zeon's Olympus Mons base, the Gundam F90 (Mars Independent Zeon Forces Type) piloted by Bosch Weller 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. The remains of both mobile suits were retrieved and Gundam F90 (Mars Independent Zeon Forces Type) was rebuilt into the F90II Gundam F90II.

In an alternate re-telling of the fight in the Mars Zeon's base, two Mars Zeon F90 were deployed. The first and original unit, piloted by Bosh, fought against several RGM-111BT Hardygun Blitzkriegs before confronting Gundam F90 Unit 1. The second unit, a copy created by Mars Zeon and given the model number of "OMS-90R2", was being upgraded in hangar 7 when Ivalu Dana decided to activate it to fend off another Hardygun Blitzkrieg.
