In the mid 1990's, as Gamera was in pursuit
of the last surviving Gyaos, the Japanese Self-Defense
Force prepared to annihilate Gamera, who was incorrectly
identified as the more dangerous foe. As the monster
crashed into the ground, an order was given to
dispatch the Type 90 tanks, a standard vehicle
for the SDF. Although Gamera cried in pain, the
ammunition failed to penetrate his flesh. The
F15J Jets were launched into battle, and Gamera
was sent tumbling onto his back. The severity
of the situation was amplified when the Gyaos
attempted to use its sonic beam on the heroic
guardian. Injured and outgunned, Gamera was forced
to retreat...
One year later, after the initial resolution
of the Gyaos threat, an extra-terrestrial swarm
of Legion became the nation's new crisis. In the
heat of the waging war, Sendai was completely
annihilated. The Type 90 tanks were again ordered
into battle, this time sent to destroy Legion.
The cannons blazed with power, but their power
proved to be futile. The queen Legion unleashed
its searing horn beam and wiped out half of the
platoon. The tanks were forced to leave at once
and regroup while the military watched helplessly
as their deadly enemy made its way to the base
of Mount Akayuka.
