G-Line Unit Type

The RX-81, unlike the mass-produced GM series that prioritized productivity and thus had considerably lower specifications than the RX-78-2 Gundam, was designed to retain the high specifications of the Gundam. Additionally, the RX-81's design incorporates the FSWS (Full-armor System and Weapon System), which allows for an increased variety of weapons and armor configurations, resulting in multiple forms that the mobile suit can change into depending on the situation. The mobile suit's backpacks can be swapped out as needed, with two thrusters for ground operations and six for space, allowing it to adapt to different combat environments effectively.
