E-70 Noizi was a tall, red robot equipped with powerful ultrasonic wave generators. It has only appeared in Fly Spy.
Noizi was set to guard Doctor Eggman's fortress. It nearly defeated Topaz and Rouge the Bat due to its ultrasonic sound waves, but was bested when Rouge threw a bomb into its main speaker, which clogged it and Topaz set the bomb off. Noizi was 8.2 meters (27 feet) tall and weighed 2.5 tons.
In the Japanese version, Noizi is sounded to have a high-pitched female voice and Dr. Eggman even referred to her as a 'she'.
