Scratch

Scratch is a Badnik of the rooster/chicken variety created by Dr. Ivo Robotnik in 3228. He is the leader of the Super Special Sonic Search and Smash Squad and one of the oldest Badniks and enemies of Sonic the Hedgehog. Upon his first attempt at capturing Sonic with his non-identical twin Grounder, they failed miserably after Sonic managed to bury them by digging a trench around them that caused a cave-in when the two broke into an argument and became distracted. He along with Grounder and Coconuts later attempted to trap Sonic and the Freedom Fighters in a virtual reality under the supervision of Dr. Robotnik, but failed again. Presumably, Scratch and Grounder then became residents in the Robo Hobo Jungle until Mammoth Mogul came in 3237 and recruited all the Badniks there to work in his Casino Night Club, and Scratch managed to get a job as the concierge for the club.

Creation
After Coconuts blasted himself- with his pieces delivered as a gift- Scratch and his non-identical twin brother Grounder had the task of stopping Sonic. They would have succeeded had they not got into an argument, during which time, Sonic left them buried. Scratch and Grounder, along with Coconuts, later appeared at a villain tryouts, with predictable results. Scratch, but not Grounder, later appeared at a company picnic to celebrate Robotnik's return from hiding following the Universalamander fiasco. (StH: #2, #4)

Later Activities
During another ill fated attempt at stopping the Freedom Fighters, Coconuts explained that Scratch was able to last, at longest, 16 seconds against Sonic. Grounder and Bat Brain both lasted longer. (StH: #11)

A subsequent battle had Scratch, Grounder, and Coconuts succesfully trap the Freedom Fighters in a virtual reality simulation using sleeping gas, but Sonic used the simulation to his advantage and smashed up the simulator and the badniks. Shortly thereafter, Scratch and Grounder had the task of robbing the Mobius Museum of Art, in an attempt to flush out a spy in Robotnik's organization. Sonic knew what was happening and sent the dumb-bots crashing into a toxic waste dump, where Scratch found a note from the spy, which added insult to injury. (StH: #16)

Working for Mogul
Scratch and Grounder, along with Coconuts, returned much later as employees in Mammoth Mogul's newly renovated Casino Night Zone. Scratch has a job as the concierge, while Grounder appears to be a chef. Both, along with butler Coconuts, had developed a fear of Sonic, a complete lack of respect for the Destructix and a (possibly greater) fear of Amy Rose. (StH: #187, #188)

Abilities
Scratch does not have much in the way of abilities. Like a real rooster/chicken, Scratch is capable of pecking foes, with the pecking more reminiscent of a woodpecker. He is also said to be the smartest of the badniks, which doesn't say much for the badniks in general.

Background Information

 * Unlike many of Robotnik's older badniks, Scratch has no direct counterpart to a classic badnik from the videogames, but his appearance is similar to the enemy Clucker (named "Kokekko" in Japan), located in the Wing Fortress Zone of Sonic 2. He was, however, a regular in the TV series Adventures of Sonic the Hedgehog, which had many elements featured in the comic before the comic's tone changed direction. He is well known because of his prominent cockadoodle-like laugh, "Ba-ha-ha-ha!".
 * Scratch, along with Grounder, currently holds the third longest resolved "non-appearance gap" in the comics at 171 issues (StH: #16-187).
