General Galaxy's entry to the Supernova Project. What makes the YF-21 unique is the use of BCS (Brain Control System) and BDI (Brain Direct Imaging) systems, wherein special equipment onboard the cockpit enables the pilot to use his brainwaves to mentally control the plane. Another distinguishing feature is its battloid mode, which resembles the Queadlunn-Rau (Meltrandi Power Suit).

Like the YF-19, the YF-21 can be fitted with a fold booster which enables it to jump from one point in space to another.
