Scooby-Doo (S&SDGAC & Be Cool, Scooby-Doo!)

Scoobert "Scooby" Dooby Doo is the eponymous character and protagonist of the animated television franchise, created in 1969 by the American animation company Hanna-Barbera. He is a male Great Dane and lifelong companion of amateur detective Shaggy Rogers, with whom he shares many personality traits. He features a mix of both canine and human behaviors (reminiscent of other talking animals in Hanna-Barbera's series), and is treated by his friends more or less as an equal. Scooby often speaks in a rhotacized way, substituting the first letters of many words with the letter 'r'. His catchphrase is "Scooby-Dooby-Doo!" He’s normally a very lovable character in the franchise, being iconic. Unfortunately, in Be Cool, Scooby-Doo! and "Shaggy and Scooby-Doo  Get a Clue!", this Scooby was badly flanderized, but, along with Shaggy, not as bad as the others.

Not Cool Qualities
'NOTE: This article only applies to the character as depicted in Be Cool, Scooby-Doo! and Shaggy and Scooby-Doo Get a Clue!'

Shaggy and Scooby-Doo Get A Clue!

 * 1) In this show, he is horrendously out of character when compared to his previous incarnations of the series (perhaps even more so than his Be Cool, Scooby-Doo counterpart), as he went from a cowardly, helpful, likable, energetic and actually funny comic relief into an extremely lazy, unlikable and generically unfunny comic relief for no real reason.
 * 2) He is part of the show’s misleading title, as he (and Shaggy) do not get a clue whatsoever in the show.
 * 3) His laziness has become obnoxious, annoying and troublesome, which is unlike his usual self, in which he’s only occasionally lazy.
 * 4) He contributed to the show’s poor grasp of source material:
 * 5) * In this show, the Scooby Snacks are portrayed like generic super power-ups for him, rather than standard food to get him and Shaggy up and running.
 * 6) * He also contributed to the show's more lighthearted tone when compared to the spooky atmosphere that previous (and later) incarnations had (and yes, that includes Be Cool, Scooby-Doo!), which does not fit Scooby-Doo at all, thus he doesn't even feel like a Scooby-Doo character and feels more like a generic kids cartoon character released in the 2000s.
 * 7) With regards to the art style, his character design looks really weird and a little uncanny. It's interesting to note that he's supposed to represent his live-action appearance from the live-action Scooby-Doo movies. It also doesn't have scelra on his eyes, unlike his other designs in the Scooby-Doo franchise.
 * 8) His humor and jokes have become mostly very poor, even for Scooby-Doo standards, only relying on fart jokes and toilet humor.
 * 9) He's part of the extremely confusing intro. It shows him running out of nowhere back and forth in silhouettes, and he’s also doing weird dances (with him coming off as either he’s typing in mid-air or he’s doing air piano, as Mr. Enter pointed out in one of his videos).
 * 10) He’s part of the stupid premise, as there is no way he and Shaggy became rich.
 * 11) He can feel like a bizarre character and not even like a mystery character.

Be Cool, Scooby-Doo!

 * 1) His redesign, while better than the human characters' designs and besides his signature brown color, dog-mouth and SD collar, hardly looks anything like his original counterpart, and instead looks more like Warner Bros. Animation's bad attempt to imitate Seth MacFarlane's art style like Family Guy, American Dad!, The Cleveland Show or Brickleberry art style.
 * 2) * Speaking of his redesign, it is unfitting in the Scooby-Doo franchise, as it fits more into an adult cartoon or parody.
 * 3) He was badly flanderized from a coward, but funny, helpful, and likable dog into an even dumber dog and a worshiper of food.
 * 4) * He even disobeyed Velma not to continue eating a food trap in one episode.
 * 5) Like Shaggy and other flanderized comic reliefs, his humor has become more unfunny, pathetic, and cruel.
 * 6) He has many laughably bad quotes, such as "Stare at us suspiciously."

Shaggy and Scooby-Doo Get a Clue!

 * 1) He was a much more likable character in all other entries outside Shaggy & Scooby-Doo Get a Clue (and Be Cool, Scooby-Doo).
 * 2) Frank Welker still does a very great job voicing him.
 * 3) He still has some genuinely funny moments.
 * 4) It is nice to see an incarnation of the series solely focused on both him and Shaggy, even if it wasn't executed very well.
 * 5) He can still be tolerable/likable sometimes.
 * 6) Some of his Scooby Snack transformations look admittedly cool.
 * 7) He thankfully improved in Scooby-Doo! Mystery Incorporated, because the writers not only made him not lazy anymore and go back to being his normal, energetic and funny self, but they also gave him more character depth to make him feel more like a fleshed-out three-dimensional character.

Be Cool, Scooby-Doo!

 * 1) He was a much more likable character in all other entries outside Be Cool, Scooby-Doo (and Shaggy & Scooby Doo Get a Clue) and has massively redeemed himself outside of Be Cool, Scooby-Doo!
 * 2) Despite the flanderization, his personality is barely even different from his usual self.
 * 3) * Also, at least he isn't as badly flanderized as his horrendous interpretation from Shaggy & Scooby Doo Get a Clue.
 * 4) * Despite his design being odd to look at, it is much better than the human characters' designs and it's passable at best.
 * He, along with Shaggy, are the most tolerable of the Be Cool, Scooby-Doo cast.
 * 1) He still has some genuinely funny moments.
 * 2) Frank Welker also still does a very great job voicing him.

Trivia

 * A lot of fans really appreciated Scooby-Doo in Scooby-Doo and Guess Who? because the producers made him smarter to go back to being normal, funny, and dumb, and removed his worship food traits to make him a more likable character.
