Dorigon (ドリゴン) appeared in episode 1 of Fireman and is the first monster Fireman fought.

Subtite: Three-Horn Monster (三本角怪獣 Sanbondzuno Kaijū)



Dorigon and her companion, Dorigorus where 100 million year old Triceratops and that hibernated in the AOE Peninsula, the pair would wake up from the there hibernation every 1 million - 1 thousand years making 1973 the year they wake up. They did this to match the spawning of the special heat absorbing algea/plankton that they fed upon, which made them what they were and allowed them to live so long.

In present day a meteor crashed into the sea, carrying with it a new specially developed fuel, which caused the sea's temperature to rise causing their food source to multiply like never before. This awoke them and the two began to gorge themselves, though the more aggressive Dorigon drove her companion away to eat in peace.

A couple hours later and Dorigon was swimming in the see until she found the Ocean Marine Institute's submarine, Sea Marine and tried to destroy it only for a Ocean Marine member to contact the Air Force Unit 12 to defeat Dorigon. Dorigon used her Heat Ray to destroy everything in her path, even the Air Force was no match. Daisuke transformed into Fireman to end Dorigon's rampage. After a tussle, Dorigon seemed defeated, but used her Energy Net to trap Fireman. Dorigon decided to swim back to the Aoe sea only for Fireman to chase her. He initially lost sight of her but her surprise attack knocked him under rubble. Fireman then jumped from under the rumble and broke off Dorigon's horns. With Dorigon weakened, Fireman used Fire Flash to kill the monster once. However the lost of its companion would cause Dorigorus to begin to rampage also, as it searched in vain for Dorigon.
