The Duel Gundam is one of four prototype
Earth Alliancemobile suits
captured by
ZAFT.
The Duel is the earliest and the most orthodox of the
GAT-X units,
and this general-purpose machine served as a development base for the more specialized
Buster
and
Strike.
The Duel is armed with a
beam rifle
and two
beam sabers,
and it carries a shield similar to that of the Strike, with an
anti-beam coating
that protects the mobile suit from energy weapons. After its capture, this machine is assigned to ZAFT pilot
Yzak Joule.
