Introduction
Gundam F-91 takes place in U.C. 0123, 30 years after the final battle between
Amuro and Char in Char's Counterattack. The colony Frontier IV, on the far end
of the Earth sphere is attacked by the Crossbone Vanguard, a mysterious military
organization with goals similar to those of the Neo-Jion. In the midst of the chaos,
high school students Seabrook Arno and Cecily Fairchild manage to gather a
dozen schoolchildren and attempt to escape the colony. However, before they can
get away Cecily is captured and turned over to the Vanguard. Seabrook fails to
save her and is shot. His friends take him and leave the colony, leaving Cecily
behind.
The Crossbone Vanguard
Cecily is introduced to Korozo, a commanding officer in the
Crossbone Vanguard who wears an iron mask. Furthermore,
Korozo claims to be Cecily's father. Korozo introduces
Cecily to her grandfather, the leader of the Crossbone
Vanguard, who tries to convince her to join them. Cecily is
dazed by the events.
The Space Ark
Seabrook and his friends run into the EMF's training warship, the Space Ark, in
the bordering colony of Frontier I. The crew of the Space Ark is busy transforming
the ship into a resistance base against the Vanguard. The Space Ark also
contains the prototype mobile suit F91. Seabrook and his friends decide to help the
engineers finish the suit and ready it for combat. Eventually Seabrook becomes pilot
of the F91 and infiltrates Frontier IV in an attempt to rescue Cecily. However,
Cecily has finally accepted her destiny by the time Seabrook finds her and has
become a mobile suit pilot with the Crossbone Vanguard. Cecily tells Seabrook
that she cannot leave yet, and helps him to escape. Seabrook regretfully returns to
the Space Ark.
Frontier 1
A Bug in Action
The EMF and the Crossbone Vanguard clash several
more times, and during these battles Seabrook's and
Cecily's New Type powers start to emerge. Eventually,
Seabrook convinces Cecily to leave the Vanguard and
join the crew of the Space Ark. As the EMF forces start
to gain the upper hand in their war with the Vanguard,
Korozo decides to use one of his final weapons. Korozo
releases the "bugs" into Frontier I in an attempt to
destroy the F91 and the Space Ark. The "bugs" are
modified bits that seek out and destroy anything they
find.
Conclusion
Appalled by the mass destruction and death the bugs cause, Seabrook
and Cecily use their New Type powers to destroy the bugs and then go
after Korozo in his Mobile Armor. Cecily's mobile suit is destroyed by
Korozo, and Cecily herself is lost in space. An enrages Seabrook uses
the F91 and his New Type powers to destroy Korozo's Mobile Armor,
killing Korozo in the process. Eventually Seabrook manages to find
Cecily using the F91, and as the two embrace the Crossbone Vanguard
retreats to regroup and prepare for future battles.
