In Scooby-Doo! and the Monster of Mexico, it is revealed by Fred that the reason Shaggy eats so much (while maintaining his slender physique) is his "high metabolism".
You'll remember that part of Shaggy and Scooby's loveable quality is their never-ending appetite and willingness to do anything for food, especially their Scooby Snacks. The series attributes this, based on their dialogue in Scooby-Doo on Zombie Island due to their constant state of terror always makes them hungry.
While Shaggy shows hints of true Paranoid personality disorder, it's clearly not full blown as he generally trusts the rest of the Mystery Inc. gang, though not fully.
Mystery Incorporated, Velma is in a romantic relationship with Shaggy, much to the distaste of Scooby-Doo. Their relationship ends in "Howl of the Fright Hound" (season 1, episode 10).
In the show, they are often used as an incentive by Fred, Daphne, and Velma to convince Scooby-Doo and Shaggy to participate in dangerous or frightening schemes, such as acting as bait for a monster.
Now you know why “Scooby Snacks” are plant-based! Shaggy has eaten meat on the show however, he did later become vegetarian when his voice actor, Casey Kasem(who was a vegetarian), insisted his character reflect that.
“I didn't expect it to blow up.” For those who have followed the long-running animated franchise, it was probably no surprise that Velma is a lesbian. Fans have heralded her as a queer icon, and previous Scooby-Doo writers and producers have tried to depict her as such for at least 20 years.
Shaggy decided to break up with Velma in favor of his relationship with Scooby, ultimately deciding that he wasn't ready for a committed relationship. Velma became irate and inconsolable at the realization that he chose a dog over her.
Fast metabolism above all else, Shaggy has constantly to run from monsters and is able to run very long distances so that burns off whatever weight he could've gained within a few minutes. The same goes for Scooby too because of how fast they run they burn off weight relatively quickly.
Unlike Scooby, Shaggy is present in the show. He is just not called "Shaggy" and is only referred to by his real name, Norville. Also, Shaggy aka Norville, like Velma and Daphne, is race-swapped and is now an African-American man instead of a Caucasian.
Daphne Blake is a fictional character in the Scooby-Doo franchise. Daphne, depicted as coming from a wealthy family, is noted for her beauty, orange hair, lavender heels, fashion sense, and her knack for getting into danger, hence the nickname "Danger-Prone Daphne".
Velma Dinkley is Shaggy's official love interest in Scooby-Doo! Mystery Incorporated; it is the first series to have an officially stated romantic relationship between the two.
Well, actually Shaggy Rogers says he likes a double triple-decker sardine and marshmallow fudge sandwich..
During production of the second season (1970), Casey Kasem became a strict vegetarian, and wanted his character Shaggy to follow suit. Kasem was promised by Hanna-Barbera that his character would become vegetarian from that point on.
Shaggy has five children, two boys from his first relationship with Carol Johnson and three girls with his wife, Rebecca. His sons are Richard Burrell Jr. and Tyler. Richard is following his father as a musician.
But Velma being gay isn't just something in queer people's minds. In addition to her funny comments in the 1970s, creators have been trying to portray Velma as openly gay for decades. Take the hit live-action Scooby-Doo movie, for instance.
Mystery Incorporated, has directly stated that Velma and Marcie Fleach are an official couple after the timeline resets in Come Undone, and even stated that Velma was a closeted lesbian before that.
While in Trick or Treat Scooby-Doo! and Scooby-Doo: Mystery Incorporated, Velma is portrayed as a lesbian, here she's better described as bisexual or pansexual. Apparently, she has crushes on both Daphne and Fred in the show, and her feelings for them are discussed early on.
But despite all his abilities, Shaggy has his weakness. For one he his a coward; along with Scooby he also fears ghosts and monsters.
Shaggy's passive allows him to enter rage. During rage, his special attacks hit harder and cover more ground. His special moves also give him armor during the attack and apply maximum stacks of weakened debuff to hit enemies. Rage is consumed after a special attack is used.
Shaggy from Scooby-Doo doesn't have a Adam's apple.
