Barugon is a gigantic quadrupedal reptile, with sharp teeth, a long horn on his snout, smaller horns above his eyes, and a long whip-like tail. He has two rows of short spikes running down his back, which begin to glow when the creature is ready to attack. Barugon also possess a very long, stiff tongue with a clubbed tip, and has blue blood.
In ancient times the Barugon egg was placed in a cave on his native island. Hundreds of years later an expedition to the Island to get the egg (thought to be a giant opal) was undertaken. The egg was then taken back to Japan to be sold. As the ship docked in Osaka one of the sailors left it under an infrared lamp meant to cure his jungle foot fungus to go play poker. While gone the lamp incubated the egg and it hatched into a baby Barugon. It then grew to full size causing the boat to explode. Barugon then headed into downtown Osaka. Rampaging the military atempted to destroy it with a missle strike but barugon destroyed it with his rainbow ray. The Radiation of the ray atracted Gamera. The two titans clashed and just when Gamera got the upper hand Barugon froze him solid. The military and Gamera out of the way Barugon left Osaka and headed for Tokyo. The miliary tried to lure Barugon to a deep lake knowing he would drown in fresh water with a large dimond on two occasions the second attempt applying infrared light. Both failed. Just as all hope seemed lost Gamera burst from his icy prison and began to fight barugon in round 2. Barugon is later presumed to be drowned to death when Gamera crushes him in a giant, deep freshwater lake.
Powers and WeaknessesEditZedus also has a similar tongue, but it has a spear-like point. His second power is an icy spray that he can fire from the end of his tounge.
