The Realdo's Flight mode can operate like a fighter jet, but with superior performances. Its excellent flight capabilities allow the Realdo to traverse long distances at a high speed, unaffected by the terrain. It can also be easily sent to different parts of the world through the use of an aircraft carrier. This is particularly relevant for the United States, the core of the Union and the self-declared "World Police", in its conduct of armed intervention in various locations. Unfortunately, the Realdo cannot transform from MS mode to Flight mode on its own, instead the process requires parts swapping in bases or similar facilities. Therefore, in-flight transformation is impossible, and the Realdo's mode is selected and set prior to launch.

The Realdo's armament consisted of a linear rifle, sonic blade, defense rod, 20mm machine gun, rocket launchers and optional missiles. The Realdos deployed in various member states of the Union have the same performance, but can differ in their colors as seen with Taribia's orange color scheme, and can also be adjusted to suit local environmental conditions such as temperature. Variant units of the Realdo include a ground type and a space type.
