The alternate version of the Sazabi. AKA novel version.


After Char Aznable, the legendary Zeon ace, reappears in the early UC 0090s and establishes the second Neo Zeon
movement, Char commissioned Anaheim Electronics to produce a
custom-designed mobile suit specifically for his Newtype abilities and
superb piloting skills. Painted in his trademark red color scheme and
insignia. (In the novel Mobile Suit Gundam: Char's Counterattack - Beltorchika's Children) This mobile suit produced was the MSN-004II Nightingale.



As is Char's fighting style, he lead's his forces from the front
with his personal mobile suit, as opposed to the rear. Char's strategy
for the Second Neo Zeon War was to force humanity into space by dropping asteroids onto the Earth to create a nuclear winter. The Earth Federation's Londo Bell
task force would lead the fight against Neo Zeon, deploying mobile
suits and nuclear missiles to destroy the asteroids. However Char used
his Nightingale and force of AMS-119 Geara Doga mobile suits to guard the asteroids until they reach the point where nothing can stop them.



During the war, Char in his MSN-04II Nightingale would duel Londo Bell Captain Amuro Ray in his RX-93-ν-2 Hi-ν Gundam.
The battle would be fierce, but the outcome is the same as in Char's
Counterattack. The psychoframe of the Hi-Nu resonated with high
emotions, pushing Amuro's already amazing Newtype powers to new heights,
and manages to actually push Axis away from the Earth. The resonance
creates a light that could be seen from Earth. The fate of both pilots
is unknown, and remains a big mystery even to this day.
