Scratch is a fictional robot in the Sonic the Hedgehog universe. He is a loyal, yet dim-witted robot who serves Dr. Robotnik throughout the cartoon Adventures of Sonic the Hedgehog, along with the short, treaded Grounder. He is a tall, roughly humanoid robot with chicken-like features, including "scaled" feet, winglike arms, a feathered tail, and a beak. Scratch seems to be the leader of the three badniks (himself, Grounder, and Coconuts), and is marginally smarter than Grounder, making up for his lack of Grounder's assorted gadgets.

Despite his best efforts, most of Scratch's attempts to capture Sonic and Tails end in complete failure. His constant failure makes Robotnik shout abuse and threaten him most of the time. Scratch is also easily tricked, as is Grounder; Sonic would often appear in disguise, as anyone from an old lady to a pizza delivery guy. Fooled time and time again by the hedgehog, Scratch and Grounder never really stand a chance, and are mainly used for comic effect.

Scratch appears to have been loosely based on the Clucker enemy from Sonic 2's Wing Fortress Zone, but in Sonic Spinball, he is an enemy in the third and final special stage where the player has to take out 6 Scratches and destroy the Egg Chamber. Multiple Scratch robots appear circling around a capsule in the third Bonus Stage of Sonic Spinball.

He is voiced by Phil Hayes in The Adventures of Sonic the Hedgehog.

Archie Comics

Scratch, along with Grounder, appeared in the earliest issues of the Sonic the Hedgehog comics published by Archie Comics where the two worked for Dr. Robotnik. However, the team's limited AI and armaments lead to many embarrassing defeats. As the Classic Badniks faded out of use, Scratch found new work in Casino Night under Mammoth Mogul. After the Super Genesis Wave, Scratch now worked for Breezie the Hedgehog.

Dr. Robotnik's Mean Bean Machine

Scratch is also a character in Dr. Robotnik's Mean Bean Machine, a game which used many characters from Adventures of Sonic the Hedgehog as opponents. He is the twelfth opponent in the game, and his AI is based on that of Rulue from the original Puyo Puyo.
