Titanosaurus was a shy, aquatic dinosaur that
was discovered by Doctor Shinji Mafune. When
he informed his colleagues about his remarkable
discovery and revealed to them that he could
control the dinosaur, they thought he was mad.
He was shunned from the scientific community,
for they didn't believe him... but the scientific
community was wrong.
Dr. Mafune's daughter, Katsura, was badly injured
in a lab experiment soon after. When the ruthless
Black Hole aliens revived her as a cyborg, they
asked for one thing in return. They wanted Dr.
Mafune to assist them in their plot to dominate
Earth. Mafune agreed, seeing it as a opportunity
to strike back at those who had shunned him from
his own field of work.
However, as the aliens prepared Mechagodzilla
for operation, Dr. Mafune went against his orders
and released Titanosaurus upon a coastal city
prematurely. Titanosaurus marched through the
city and caused massive destruction until Godzilla
appeared. The two monsters exchanged physical
blows. The vile, vermilion monster started to
gain an advantage when he used his tail fin to
create a powerful wind, which knocked Godzilla
off balance. The two titans' confrontation was
cut short, though, when a group of Interpol agents
shot Katsura off a nearby cliff, causing Mafune
to order Titanosaurus into retreat in order to
save her. The injured Katsura was brought back
to the Black Hole Alien's base, and, again, they
saved the young girl's life. Mafune assured them
of his allegiance this time, after saving the
life of his daughter twice, and that he would
deploy Titanosaurus at their will from then on.
The Black Hole Aliens and an alterative motive
in saving Katsura the second time, though, as
they later revealed to Mafune that they had inserted
Mechagodzilla's control unit into the girl, putting
the Doctor's own emphasis on the importance of
living brain tissue to task. With final preparations
made on the robot monster, Mechagodzilla and Titanosaurus
were sent to attack Tokyo, but Godzilla came to
face the duo. Godzilla first engaged in a fierce
battle with the crimson creature. Titanosaurus
seemingly defeated Godzilla by burying him in
a ditch, but he quickly lost the upper hand. The
humans managed to exploit Titanosaurus' one weakness:
sonic waves. A sonic waves gun was created in
order to deal with deadly dinosaur. The weapon
was unleashed, and it effectively stunned Titanosaurus.
Godzilla emerged from the ditch and began to attack
Mechagodzilla. After a fierce battle, which included
the removal of Mechagodzilla's head, Godzilla
finally destroyed his robotic double once and
for all. With the mechanical menace finally defeated,
Godzilla turned his attention to the weakened
Titanosaurus. Godzilla fired his radioactive ray
and sent his final opponent tumbling off of a
cliff back to its watery home.
Titanosaurus was defeated, and whether or not
he was ever seen or heard from again is a complete
mystery...
