The Wall-Upper 3000[1] is a character that appears in Sonic the Hedgehog 3: Up Against the Wall. It was a giant robot built by Dr. Robotnik.


The Wall-Upper 3000 is an olive green, tractor-like robot with multiple gray claws and a small screen on the front of it.


The Wall-Upper 3000 was constructed by Dr. Robotnik to build a wall around the Great Forest and put a dome over it to keep out sunlight and fresh air. While conducting its construction efforts however, it attracted the attention of the Knothole Freedom Fighters.[1]

Formulating a plan of attack, the Freedom Fighters managed to incapacitate Robotnik and the Swat-bots guarding the Wall-Upper 3000. Sonic the Hedgehog then arrived and put a canvas of a fake scenery over the Wall-Upper 3000's eyes. He used this to lure the machine over a cliff to its doom.[1]
