This prototype
mobile suit
was developed by the
Titans
at the
Grypsspace colony.
Based on the legendary
RX-78 Gundam,
the Mk.II inherits its predecessor's high performance and remarkable potential, although it suffers from a few lingering design flaws - notably, its obsolete
armor
materials. On the other hand, the Mk.II also introduces the radical new
"movable frame"
design concept, giving it superb maneuverability. All three prototype units are captured by the
AEUG
resistance group during their raid on the Titans' headquarters. The rebels keep one in service, replacing its sinister "Titans colors" with a more heroic white and blue scheme, and eagerly dissect the other two in order to learn their technological secrets.
