Classification: Frilled Monster
Bearing an unmistakable likeness to the King of the Monsters, Jirass is a giant frilled aquatic reptile created (or is it found?) by the mad scientist Professor Nakamura (aka. Professor Nikaido) and raised in Lake Kitayama.
After Jirass's life in Lake Kitayama was disturbed and he was brought forth by his caretaker to attack the Science Patrol, Ultraman defeated Jirass in an uncharacteristically showy and brutal battle in which Jirass's frilled collar was ripped from his neck. After Jirass died, Ultraman knelt before the defeated monster to show his respects.
Height: 147 feet (45 meters)
Weight: 25,000 - 30, 000 tons
Powers: Like Godzilla, Jirass is an accomplished swimmer, but where Godzilla fires a blast of atomic breath, Jirass unleashes a blue electric ray from his mouth instead.
