Dr. Eggman used several of these robots to demolish the resort in the Emerald Coast and build the Eggman's Scream Park in its place. When Sonic the Hedgehog arrived, they combine into a long snake-like robot called Serpenter, that was destroyed by Amy. A Quizon is one meter (3 feet) tall and weighs 150 kg (330 lbs).
- In the Japanese version, the Quizon robots are capable of speech. However, they are mute in the English dub.
