|This article is about a/an monster in Kamen Rider, the original series.|
The first Pirasaurus had the human guise of a bus driver, and after using his death gas ability to kill the people in a bus it was discovered his poison was so potent it killed him as well. Pirasaurus was a project from Shocker commander Maya (マヤ Maya), and she quickly looked for a stronger person to be altered.
The second Pirasaurus was pro-wrestler Noboru Kusaka (草鹿昇 Kusaka Noboru). He was captured, brainwashed and had his body altered, becoming the perfect Pirasaurus. The new Pirasaurus was able to match and defeat Kamen Rider 2 with his Ultra Kick. Brainwashed, Kusaka returned to the wrestling world as Satan Mask and attacked his own brother when he tried to speak with him. He eventually faced Rider 2 in a wrestling ring. During the battle, he accidentally killed his commander Maya with his poisonous gas. At the end of episode 17, Kamen Rider 2 and Pirasaurus exchanged a Rider Kick and an Ultra Punch. Afterward, both fell on the ring and Kusaka returned to human form, recovering his memories.
The Pirasaurus Human's main ability, engineered from the original Pirasaurus, was releasing a poisonous breath. Appearing as a powerful mist, the Pirasaurus' poison was said to be able to kill a dinosaur in seconds. During its test run, the poison of the Pirasaurus Human was able to kill a bus full of humans, however, the poison was so potent it resulted in the Pirasaurus Human dying immediately after, thus a stronger human was needed to be modified. The second Pirasaurus, Noboru Kusaka, had an unbelievably strong body, able to shrug off rounds of a cannon, and special techniques called Ultra Punch and Ultra Kick, similar to the Rider Punch and Rider Kick.
