Examples of the Over Flag's enhancements included a High-Speed Flight mode, high output flight units that are hard to control but grant improved speed, and anti-beam coating on its surface for better resistance to the beam weaponry of the Celestial Being's Gundams. The mobile suit's dark colors are also due to this coating. Despite some identical enhancements, the Over Flag does not have the risky elements of the Custom Flag, like the disabling of the anti-G limiter requested by Graham, to reduce the stress placed on its pilots. It also lacks the Custom Flag's reduction in hydrogen fuel payload and lightweight armor materials, and is heavier than the Custom Flag and the Union Flag.
A few years later, in AD 2311, Over Flags with colors switched to those of the Earth Sphere Federation's are spotted, and they are known as 'Over Flag ESF Type'. In AD 2312, the head of Daryl Dodge's Over Flag is utilized in the creation of Graham Aker's GNX-U02X Masurao. In AD 2314, space-use version of the Over Flag, the SVMS-01OA Over Flag Astro Package, is one of many mobile suits that participated in the battle with the alien life form, the ELS.
