When Topaz and Rouge attempted to steal the Chaos Emerald at Dr. Eggman's fortress, Noizi was alerted to this theft and attacked them. It nearly defeated the agents 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, destroying it.
- In the Japanese version, Noizi is sounded to have a high-pitched female voice and Dr. Eggman even referred to the robot as a 'she'.
