Main characters
Scooby-Doo
Scooby-Doo is the eponymous character in the Scooby-Doo animated television series created by Joe Ruby and Ken Spears alongside the popular American animation company Hanna-Barbera. Scooby-Doo is the pet and lifelong companion of Shaggy Rogers and in many iterations, including the original series, is regarded as a unique anthropomorphic Great Dane dog who is able to speak in broken English, unlike most other dogs in his reality, and usually puts the letter R in front of words spoken. Other incarnations, such as A Pup Named Scooby-Doo, present talking dogs like Scooby as quite common.
The head of children's programming at CBS, Fred Silverman, came up with the character's name from the syllables "doo-be-doo-be-doo" in Frank Sinatra's hit song "Strangers in the Night".
From 1969 to 1994, Scooby was voiced by Don Messick. In the 1997 episode of Johnny Bravo, Scooby was voiced by Hadley Kay. From 1998 to 2001, he was voiced by Scott Innes, who also voiced the character in video game projects (including PC, DVD and board games), commercials and some toys until 2008. In Scooby-Doo and Scooby-Doo 2: Monsters Unleashed, Scooby was voiced by Neil Fanning. Scooby is currently (2002–present) voiced by Frank Welker (the voice of Fred Jones). For parody versions, Scooby was voiced by Mark Hamill in Jay and Silent Bob Strike Back and Seth Green and Dave Coulier in Robot Chicken.
Shaggy Rogers
Norville "Shaggy" Rogers is Scooby's owner and best friend. Shaggy is a cowardly slacker more interested in eating than solving mysteries. His catchphrase is "Zoinks!".
From 1969 to 1997, Shaggy was voiced by Casey Kasem; he would return to voice him again from 2002 to 2009. In Scooby-Doo on Zombie Island, Shaggy was voiced by Billy West. From 1999 to 2001, he was voiced by Scott Innes, who also voiced Shaggy in video game projects (including PC, DVD and board games), commercials and some toys until 2009. In Shaggy & Scooby-Doo Get a Clue!, Shaggy was voiced by Scott Menville. Shaggy is currently (2010–present) being voiced by Matthew Lillard, who played Shaggy in the live-action theatrical films. He was portrayed by Nick Palatas in the Cartoon Network prequel films, Scooby-Doo! The Mystery Begins (2009) and Scooby-Doo! Curse of the Lake Monster (2010). Will Forte voices Shaggy as an adult with Iain Armitage voicing his younger self in the theatrical animated film Scoob!.
Fred Jones
Fred Jones, sometimes called "Freddie", is the de facto leader of the gang and normally drives the Mystery Machine. He is often constructing various Rube Goldberg traps for villains, which Scooby-Doo and/or Shaggy would often set off by mistake, causing the villain to be captured another way. Fred usually takes the lead in solving mysteries, often pairing with Daphne and Velma. He is sometimes shown in a romantic pairing with Daphne.
In A Pup Named Scooby-Doo, Fred was depicted as being somewhat less intelligent, believing in legends such as Bigfoot and mole people and often wrongly blaming the crime on the neighborhood bully Red Herring. In the episode "The Song of Mystery" from Scooby-Doo! Mystery Incorporated, he is called Fredrick by his tutor Mary-Ann Geerdon, but is called Fredward in Scooby-Doo! Adventures: The Mystery Map.
Fred is voiced by Frank Welker, who has retained this role throughout every incarnation of each series where Fred is portrayed as a teenager from 1969 to 1984 and again since 1997. In A Pup Named Scooby-Doo, he was voiced by Carl Steven. He was portrayed by Freddie Prinze Jr. in the 2002-2004 live-action films and by Robbie Amell in the Cartoon Network prequel films, Scooby-Doo! The Mystery Begins and Scooby-Doo! Curse of the Lake Monster. Zac Efron voices Fred as an adult while Pierce Gagnon voices his younger self in the theatrical animated film Scoob!.
Daphne Blake
Daphne Blake is a beautiful, fashionable young girl from a rich family. Portrayed as an enthusiastic, but also clumsy and danger-prone (hence her nickname "Danger-Prone Daphne") member of the gang, she serves as the damsel in distress and would occasionally get kidnapped and imprisoned, only to be saved by the gang. As the franchise progressed, she became a stronger, more independent character in some iterations, with a return to her danger-prone self in others.
Daphne is shown to have a number of hobbies and physical prowess due to her rich upbringing. She also occasionally assists the gang by using beauty products in novel ways. Her catchphrase is "Jeepers!".
Daphne was initially absent alongside Fred and Velma in the 1980s, with the franchise focusing on the comedy antics of Scooby, Shaggy, and Scrappy. However, when the "Whodunnit?" aspect returned to the series with The New Scooby and Scrappy-Doo Show (later retitled The New Scooby-Doo Mysteries), Daphne returned. She also appeared in 13 Ghosts of Scooby-Doo.
Daphne was voiced by Stefanianna Christopherson from 1969 to 1970. She was replaced by Heather North who would voice Daphne until 1997 and again for the two direct-to-DVD movies, Scooby-Doo! and the Legend of the Vampire and Scooby-Doo! and the Monster of Mexico. Daphne was voiced by Mary Kay Bergman from 1998 to 2000. Daphne has been voiced by Grey DeLisle since 2001. In A Pup Named Scooby-Doo, Daphne was voiced by Kellie Martin. She was portrayed by Sarah Michelle Gellar in the 2002-2004 live-action films and by Kate Melton in the 2009-2010 live-action telefilms. Amanda Seyfried voices Daphne as an adult with Mckenna Grace as her younger self in the theatrical animated film Scoob!.
Velma Dinkley
Velma Dinkley is portrayed as a highly intelligent young woman with various interests, leaving her with a wide breadth of knowledge in obscure topics. Consequently, Velma is usually the one to figure out the mystery, sometimes with the help of Fred and Daphne.
A running gag in the franchise is Velma's severe near-sightedness and her trouble with keeping her glasses on her face (usually after falling off while being chased by the villain). Her catchphrases are: "Jinkies!" and "My glasses! I can't see without my glasses!"
In the original Where Are You! series, Velma attended the same high school as the rest of the gang (as stated in the episode "What a Night for a Knight"). However, in the second series, The New Scooby-Doo Movies, Velma is said to have graduated from a different high school than her friends (as stated in the episode "Spirited Spooked Sports Show").
Velma was voiced by Nicole Jaffe from 1969 to 1973, who would voice the character again in the two direct-to-DVD movies, Scooby-Doo! and the Legend of the Vampire and Scooby-Doo! and the Monster of Mexico. Jaffe was later replaced by Pat Stevens, who would voice Velma from 1976 to 1979; Marla Frumkin replaced her from 1979 to 1980 and would voice the character again in 1984. Velma was voiced by B.J. Ward from 1997 to 2002, by Mindy Cohn from 2002 to 2015 and in A Pup Named Scooby-Doo, Velma was voiced by Christina Lange. Starting with Be Cool, Scooby-Doo! (2015–2018), Velma has been voiced by Kate Micucci. Gina Rodriguez voiced Velma as an adult with Ariana Greenblatt voicing her younger self in the animated theatrical film Scoob!. She was portrayed by Linda Cardellini in the 2002-2004 live-action films and by Hayley Kiyoko in the 2009-2010 live-action telefilms.
Secondary characters introduced in The Scooby-Doo Show/Scooby-Doo and Scrappy-Doo
Scrappy-Doo
Scrappy-Doo is Scooby-Doo's feisty nephew. He was added to the cast of Scooby-Doo to save the franchise's low ratings, which threatened to cause its cancellation. After his addition to the show proved to be a ratings success, Hanna-Barbera restructured the show around Scrappy in 1980. The original format of four teenagers and their dog(s) solving supernatural mysteries for a half-hour was eschewed for simpler, more comedic adventures which involved real supernatural villains (the villains in previous Scooby episodes were almost always regular humans in disguise).
Scrappy remained an integral part of the Scooby-Doo franchise, on both television and in Scooby-related licensed products and merchandising, through the end of the 1980s. He was also briefly the star of his own seven-minute shorts — the Scrappy and Yabba Doo segments of The Scooby & Scrappy-Doo/Puppy Hour. Teamed with his uncle Yabba-Doo and Deputy Dusty, he helped maintain law and order in a small town in the American west. In later years, the presence of Scrappy-Doo has been criticized as having had a negative effect on the various Scooby-Doo series of the 1980s. However, the gradual decline of Scooby-Doo has been credited to other factors as well, such as changes in format. Scrappy-Doo has become the symbol of an irritatingly overexuberant or cute character added to a series in an attempt to maintain ratings, a phenomenon also known as Cousin Oliver Syndrome.
Due to the general perception of the character by audiences, Scrappy-Doo has rarely appeared in modern media. He appears as an antagonist in Scooby-Doo (2002), where he seeks revenge on Mystery Inc. for abandoning him and got corrupted by the Daemon Ritus. In Velma, Scrappy is depicted as an artificial lifeform created by Project SCOOB!.
Scrappy was voiced by Lennie Weinrib from 1979 to 1980. Weinrib was later replaced by Don Messick, who voiced Scrappy from 1980 to 1988. Scott Innes voices Scrappy in Scooby-Doo (2002) and Harvey Birdman, Attorney at Law.

Scooby-Dee

He was subsequently sent to jail with Sheriff Stone asking "Say it isn't so?" Mayor Fred Jones Sr.'s arrest led to Janet Nettles becoming the new Mayor of Crystal Cove.
In season two, Fred Jones Sr. was seen in prison as Mystery Inc. left some items in his care to keep the items out of Professor Pericles' clutches.
In the rebooted timeline depicted in the series finale "Come Undone", Fred Jones Sr. is the principal and soccer coach of Crystal Cove High School.
