Serpenter

E-39 Quizon is a construction robot with four arms with various tools.

History
Dr. Eggman used several of these robots to demolish the resort in the Emerald Coast and build an amusement park in his image 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).
