Adventures of Sonic the Hedgehog Wiki


D.U.F.U.S. is Dr. Quark's only robotic creation and minion. His name stands for "Design Unit Flexible Underling Substitute".


D.U.F.U.S only made two appearances, one in Robotnik's Rival & also in Super Special Sonic Search & Smash Squad.


D.U.F.U.S., at the beginning of the episode, was a logical machine. He was loyal, and liked to present the odds of outcomes through calculations. However, near the end of the episode, due to malfunctions in his programs, he becomes more rebellious. He, then, begins to resemble a laid back surfer type, begins acting insubordinate, and eventually stops obeying Dr. Quark.

Physical Appearance[]

D.U.F.U.S. has a humanoid, dark green body. He appears very bulky and has four red circles on each side of his torso. He has two, fairly angry looking, red eyes, resembling Grounder's.


D.U.F.U.S.'s solid body is very flexible, almost to the extent of being a liquid. He can freely change his body's features, and change shapes. He has, among other things, created a wheel to move around on, turned into a cage to trap Sonic, turned into a picnic table, a bench, and a surfer riding a wave.


"You summoned me, Dr. Quark?"

"I am a prototype D.U.F.U.S., capable of 2486 offensive modes."

"This failure was probable to a factor of 245,764 to 1. Of course, the mathematical probability can be altered; if you were to combine forces, the success slash failure ratio, is 4,062 to 1."

"Sorry, dude. Surf's up."
