In order to initiate their invasion of the
Planet Earth, the Mysterians constructed a hidden
underground base in the Mt. Fuji area of Japan.
Without the denizens of Earth knowing their plans,
they constructed a massive, burrowing dome as
protection for their subterranean domain. Traps
were situated around the dome soon afterward,
and the base was completely guarded against attack.
Finally, in order to commence their invasion with
a bang, the Mysterians unleashed their giant robot:
Moguera, and awaited the response...
Upon the defeat of Moguera, and amongst growing
worries that extra-terrestrials were the bane
of these recent disasters, a few scientists investigated
a lake at Mt. Fuji, a locale particularly noteworthy
for mysterious goings-on. The stunned scientists
looked on in awe as the gigantic dome emerged
from the Earth. Their fear and amazement skyrocketed
when a voice emanated from the structure, requesting
the presence of a small group of people, including
the famous Dr. Adachi. Donning capes due to the
frigid environment within the alien base, the
humans journeyed deep inside. These ambassadors
of Earth soon became outraged however, at the
request of these "Mysterians". Though
they only appeared to desire a small parcel of
land, they also demanded the right to marry the
Earth women of their choosing. Following the meeting,
a plan of attack was put into place...
The Japanese Self-Defense Force gathered their
forces at the Fuji Area in order to stage an assault
against their primary target: the Mysterians'
Dome. Planes and missiles bombarded the base with
a barrage of ammunition; however, the Mysterians
within chuckled as their own flying ships were
dispatched... for they understood the futility
of the human offensive. The dome fired intensely
hot beams of burning energy at the ground forces,
melting the puny machinery like wax. The jets
were also annihilated by the Dome's energy defenses
and UFO assistance. One tank valiantly continued
its approach within a proximity seemingly too
close for the Mysterians' defenses to protect
against. Unfortunately, the ground suddenly collapsed
into a whirlpool and sucked the war machine underground,
killing both of the soldiers inside. The dome
sank deep into the subterranean realm; it seemed
invincible!
Humankind was not discouraged however, and another
assault was planned using two enormous vessels
known as the Alpha Class Aerial Battleships. Dr.
Adachi and several UN officials piloted the BETA-2
in order to test if the ships were indeed resistant
to the Dome's heat rays. The craft appeared to
be well guarded against the aggressors at first,
until the other Alpha Class Aerial Battleship
was destroyed when it took too much abuse from
the ray. The BETA-2 was ordered to pull back as
those inside began to come to the conclusion that
their efforts were hopeless.
An ultimate showdown was planned when the humans
finally found a device that could stand up to
the Mysterians' stronghold. The Markalite Cannon
was the weapon that could finally tip the tables
in favor of the Earthlings. It could resist any
amount of heat and unleashed powerful atomic heat
rays itself. It could only work for 45 minutes
however, so the BETA-2 was equipped with an electron
gun for added support.
Meanwhile, a human named Joji Atsumi infiltrated
the dome and pressed deep into the heart of the
facility. He wished to save the women whom the
aliens had absconded with. Assistance came in
the form of Ryoichi Shiraishi, Joji's former friend
who had defected to the Mysterians due to the
allure of their extreme technological advancements.
Ryoichi, however, now decided to betray the Mysterians,
for he had discovered that they wished to conquer
the whole world.
As the drama continued to unfold within the Mysterians'
fortress, the Markalite Cannons and BETA-2 arrived
outside of the dome. The towering Markalites clearly
began to prove their strength as they easily withstood
the Markalite's power. The alien base slowly began
to weaken from the inside out too, as Joji destroyed
a great deal of machinery within the dome. Ryoichi
helped Joji and the captured women escape, as
he sacrificed himself in an attempt to further
weaken the Mysterians defenses.
The Mysterians Dome still had a few tricks up
its sleeve, however. A massive flood of water
rose from the lake and washed a Markalite Cannon
away. In the process, a nearby town was leveled.
Another Markalite Cannon was destroyed as a second
Moguera rose from the ground. Fortunately, the
robot was crushed by the falling weapon. The BETA-2
used its electron gun one final time on the dome,
and the weakened facility began to explode. The
alien leaders escaped before it was too late,
but unfortunately for them, the dome was completely
destroyed shortly after they fled. Nothing remained,
save a glowing pile of rubble...
