Scratch: "Look at em' run! Fear, panic, dread, terror! Bwahaha!"
Grounder: "Yeah! Makes you proud to be a robot! Ha ha!"
~ Scratch and Grounder in Over The Hill Hero.

Scratch and Grounder are the secondary antagonists of The Adventures of Sonic The Hedgehog. They are Dr. Robotnik's dimwitted henchmen and the main members of the S.S.S.S.S. Squad. They occasionally make appearances in other Sonic Media.

Scratch was voiced by Phil Hayes and Grounder was voiced by Garry Chalk.



Scratch is a fictional robot in the Sonic the Hedgehog universe. He is a loyal, yet dimwitted robot who serves his "father" Dr. Robotnik, who created him and his brother Grounder, 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 - though Scratch does possess a laser pistol, a drawstring and hands that can turn into scissors.

Mean Bean Machine

Scratch in Mean Bean Machine

Scratch makes an appearance in the puzzle game Dr. Robotnik's Mean Bean Machine. He is the semifinal boss who you fight on stage 12 and is almost as difficult as Dr. Robotnik himself. However, his style of gameplay causes him to do stupid things, which can end up killing himself.


Grounder is a loyal, yet dimwitted robot who serves Dr. Robotnik, who first created his "twin brother" Scratch and was cloned with part of a tail feather. However, because Scratch pulled a lever on the machine that wasn't supposed to be pulled, he came out entirely different to Scratch.

Grounder is a short teal mole-based robot with continuous tracks for mobility. He has a drill for a nose as well as two on the ends of his arms. Grounder specializes mainly in gadgetry; he can turn his drill "hands" into any number of weapons or tools (including actual hands), stores assorted equipment (commonly, a telephone) in his torso, and (according to the episode showing his creation) even has the components of a Swiss Army knife installed in his tongue. Grounder also seems to be the most fragile of Robotnik's robots (himself, Scratch, and Coconuts), getting blown to bits slightly more often than the others.

Grounder appears as the eight opponent in the puzzle game Dr. Robotnik's Mean Bean Machine. He is the last opponent one could consider easy. However, he still isn't a pushover either. He is the margin point where the game becomes much more difficult.

Scratch: "He made me first. I'm his favorite!"
Grounder: "Yeah!? I've got more accessories! He likes
me best!"
(Scratch turns around, then kicks a rock to Grounder's head.)
Grounder: "You did that on purpose! Why you-!"
(Grounder then pecks at Scratch's behind with his nose.)

  • Scratch and Grounder are both based off of badniks from the mainstream games, specifically Sonic the Hedgehog 2: Scratch is based on the Clucker model while Grounder is based on the badnik of the same name.
  • Scratch and Grounder started a trend of Dr. Robotnik having two incompetent sidekicks.
