Rodan is an overgrown pterosaur made by the Toho company. He doesn't really have any special powers except for being able to blow a concentrated blast of wind from his beak, but is 70 meters long, has an 150 meter wingspan, and can fly at mach 1.5. He is one of Godzilla's greatest allies, and is probably the most popular kaiju ever.
Rodan just annoyingly shook his head and wasn't hurt when hit by Godzilla's Atomic Ray. He also just shrugged King Ghidorah's beam off. Also, most people believe that this kaiju is either one of the or the fastest kaiju.
