E-70 Noizi was a tall, red robot equipped with super powerful sound wave generators.
Noizi was set to guard Doctor Eggman's fortress. He nearly defeated Topaz and Rouge the Bat due to its 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.
