Scratch and Grounder (Adventures of Sonic the Hedgehog)

Scratch and Grounder are the secondary antagonists of the American animated series, Adventures of Sonic the Hedgehog. They're Dr. Robotnik's dim-witted henchmen and the 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.

Overall

 * 1) Since the show focuses on the villains much more, they, along with Robotnik, sometimes steal the show with their failed attempts to subdue Sonic for a huge reward, which usually comes off as hilarious.
 * 2) Just like Harry and Marv: They make a perfect relationship in crime.
 * 3) * They also serve as villainous comic reliefs we laugh at because of their dimwittedness & incompetence, meanwhile Sonic is the radical yet guileful and heroic trickster that we root for.
 * 4) ** This is further exaggerated where they are portrayed as anti role models in the Sonic Sez segments compared to the moralistic Sonic.
 * 5) * While they may be two comically incompetent & easily deceived crooks, but they have had their moments of imposing a credible threat towards Sonic in both the show or in the Christmas special Sonic's Christmas Blast.
 * 6) They have shown to have great chemistry, as many episodes had shown that despite their contrasting looks and their vitriolic, opposed behavior, they always have each others’ backs. Mainly out of determination and loyalty.
 * 7) These two, along with the titular trio in Ed, Edd, N Eddy, are gods of durability (considering that these guys are robots, this is saying something).
 * 8) * In which, their clownish antics & screw-ups pay homage to other classic cartoon characters such as Sylvester or Wile E. Coyote.
 * 9) Despite being robots, they sometimes portray humanlike features like producing tears, showings signs of anger, fear, or joy as emotions.
 * 10) Phil Hayes and Garry Chalk did a great job at voicing them.
 * 11) Their character designs are quite appealing all things considered.
 * 12) They have had many ludicrous and/or flat-out hilarious moments because of their silliness, mainly Scratch with his cheeky and mostly jokey dialog.
 * 13) They also had spawned some memes out of their idiocy and buffoonery, such as Scratch holding his "booze" or both characters dancing in a goofy 70s fashion with wearing buffoonish outfits for example.

Scratch

 * 1) Despite being an idiotic buffoon along with Grounder for comedic purposes, he can be somewhat competent and assertive with some of his plans to defeat Sonic, especially when following most of Robotnik's plans carefully, even if he does screw up at doing that in end.
 * 2) The way he laughs is goofy, yet pretty iconic and funny.
 * 3) His voice is not only funny, but it also fits his character.
 * 4) The ways his traps for catching Sonic keep backfiring on him are very funny. Especially when his fallible ego or acts of stupidity can be the result of this (e.g being easily sidetracked in a ditzy & gullible way along with Grounder in the first episode "Super Special Sonic Search & Smash Squad").

Grounder

 * 1) His butt-monkey status is hilarious and warranted, especially when he serves as the dumber one between the two.
 * 2) Speaking of which, much like Billy: His idiocy is often hilarious and fun to watch.
 * 3) A lot of the gadgets he keeps inside his chest compartment/etc are either interesting, bizarre, comedic, and sometimes useful.

Overall

 * 1) Their backstory is not all that interesting, especially when they were essentially built on the same day for the purpose of capturing Sonic.
 * 2) The constant, running gag of their sheer ineptitude at their rivalry with defeating Sonic & screwing up at anything because of their idiocy or carelessness, can get a bit stale since it can be boring for them to lose over and over time again.
 * 3) They can get irritating, especially when Scratch and Grounder always fall for Sonic's obvious plans or annoy others because of their stupidity in a predictable fashion.
 * 4) Like Roger Rabbit: Their over-the-top voices and antics can come off as polarizing, especially when viewers can either find them charming or annoying by personal preference.
 * 5) They have done some mean-spirited stuff as their job title with being Robotnik's goons, examples of this include them occasionally being seen harassing random Mobian citizens for no good reason, and once they even attempted to beat up an old, anthro (and seemingly weak) crane.

Scratch

 * 1) His loyalty for Robotnik (while true-blue for the most part) can be all over the place with foolishly tagging along with other characters on occasion if a bit justified since Robotnik is just that ruthless (e.g Scratch being a lackey to the domineering, overconfident Grounder in the episode "Grounder The Genius" with being disloyal to Robotnik).
 * 2) His laugh can come off as annoying to some.
 * 3) He is often arrogant, selfish, and smug. Such to the point that it can cause him backfires on his plans.

Grounder

 * 1) He often screws things up very easily and can be too dumb to be cooperative, even more than Scratch because of his own brand of sheer stupidity.
 * 2) Grounder occasionally wears women's clothing to complement Scratch whenever they find it necessary to put on costumes. Which often comes off as suggestive and even weird for a kids' show (if somewhat silly in an ironic way).
 * 3) * In "Super Robotnik," when Scratch dresses up as a doctor, Grounder plays his role as a nurse, in "Zoobotnik," when Scratch serves as the best man at Robotnik's (forced) wedding, Grounder is the maid of honor, when they transform themselves into wedding cake figurines in "Hedgehog of the Hound Table," Scratch is the groom and Grounder is the bride.

Trivia

 * Jim Cummings originally voiced Scratch in the pilot.
 * Scratch is often referred to as a robotic chicken, which seems like it predated a similar name from a certain show on Adult Swim.
 * Robotnik noted that Grounder is Scratch's exact twin, despite them looking nothing like each other.
 * Garry Chalk would later on voice Robotnik in Sonic Underground.
 * Scratch and Grounder were featured in Dr. Robotnik's Mean Bean Machine. And were rather challenging to beat.
