Main

• Bugs Bunny (voiced by Jeff Bergman) – lives a life of upper-middle-class suburban leisure, based on income from a popular Carrot Peeler that he invented; instead of an underground borrow from the theatrical shorts, Bugs lives in a well-appointed house, drives a compact car, and provides room and board for his long time acquaintance and arch-nemesis: Daffy Duck. Bugs spends his time watching sports or sitcoms on TV, hanging out with his friends and neighbors, and dating Lola Bunny. Bugs generally plays the straight man to Daffy and Lola's various bouts of insanity, although Bugs is not without his own quirks. Bugs has exhibited somewhat compulsive/addictive tendencies, like having a high caffeine intake with coffee, becoming addicted to an energy drink that had dangerous chemicals in it, nearly leveling his own house in an increasingly deranged attempt to put up a shelf, playing "Gribbler's Quest", and getting hooked on foods that contain butter. Despite being intelligent, Bugs has shown some level of tomfoolery, such as when he found jail "a smart aleck's paradise" and mistook the Tasmanian Devil for a dog. In the second season, the colour of his fur changed from purple to grey.
• Daffy Duck (voiced by Jeff Bergman) – is the archenemy-turned-roommate of Bugs Bunny. Unlike Bugs, Daffy is an incompetent, loud, unproductive leech and an ungrateful user that has no way of earning money and relies on Bugs for food and shelter. He also has a high maintenance streak as he demands far more from his friends than he deserves and takes high advantage of gullible Porky, his other "best friend". Like in the classic shorts, Daffy constantly hatches get-rich-quick schemes that end up failing repeatedly. While Daffy's greed and jealousy of Bugs remains, it appears less antagonistic in the show. In the first episode, Bugs openly admits that Daffy is his best friend, despite his faults. Daffy has worked, and been fired from, numerous jobs due to negligence and/or incompetence. Despite this, however, Daffy has shown to be a very skilled hairdresser and successfully graduated beauty school. Daffy's three possessions that he is proud of are his blue recliner, his white collar which he always wears, and his Papier-mâché parade float, constructed on top of a pickup truck, which is his main means of transport. Daffy resembles Chuck Jones' version of Daffy in which this is the penultimate time of this version's use as later versions more closely resembles Tex Avery's original version of the character with the screwball personality.
• Porky Pig (voiced by Bob Bergen) – is one of Bugs Bunny's friends and Daffy Duck's best friend. Despite being bright and bookish, Porky has an innocent, naïve quality that Daffy frequently uses to his advantage, tricking Porky into parting with large sums of money or accompanying him in bizarre schemes. Porky originally worked a boring office job as an accountant, but got fired following Bugs' example. Porky started his own catering company afterwards. In "Dear John", Porky was shown to have served on the city council. Towards the end of the series, Porky starts a relationship with Petunia in the end of the Season 2 episode "Here Comes The Pig". In "Best Friends Redux", Daffy meets Porky's young self and ensures that Porky becomes good friends with Bugs & Rodney in their cabin, finally showing Porky an act of kindness.
• Speedy Gonzales (voiced by Fred Armisen) – is an extremely fast male mouse who lives with Bugs and Daffy as their "mouse in the wall" and runs a pizza parlor called Pizzarriba. Speedy is one of the brighter, more level-headed characters as he is not afraid to speak his mind (even standing up to Bugs at times, despite living rent free in a mouse hole in Bugs house) and has occasionally shown to act as Daffy's conscience. The episode "Sunday Night Slice" showed that Bugs bought his favorite restaurant Girardi's to prevent it from being closed and hired Speedy to help him. When Bugs spoke to Speedy about the fact that he doesn't want to own a restaurant anymore, Bugs himself hands ownership of it to Speedy, renaming it "Pizzarriba" as a gift to Speedy.
• Yosemite Sam (voiced by Maurice LaMarche) – a quick-tempered cowboy who is one of Bugs and Daffy's neighbors. Sam is a liar, a thief and a cheat, amongst other things. Coming from a lower-class background, Sam tends to steal Bugs' possessions, causing Bugs and Daffy to resent him. His full name was revealed as Samuel Rosenbaum.
• Lola Bunny (voiced by Kristen Wiig) – is Bugs' scatter-brained, bubbly and obsessive girlfriend, who has a habit of speaking rapidly, whether anyone else is listening or not. When they first meet, Bugs falls in love with her, but after learning how crazy and ditsy Lola is, Bugs loses interest and often tries to escape her company. Lola develops a huge obsession with Bugs Bunny that Daffy initially finds creepy, however in later episodes Daffy and Lola become friends as neither one is very bright. Lola is never put off by Bugs' responses to behavior, that include taking photos of him in the shower, sneaking up on him late at night and often stalking him. Later in the series however, Bugs eventually falls in love with Lola again which started when they went to Paris in the episode "Eligible Bachelors" and Bugs manages to stop her talking for a while. Her parents are members of a country club and her father likes Bugs so much that he considers him to be "The son I never had." Lola was redesigned in both appearance and personality to match the series.
• Tina Russo (voiced by Jennifer Esposito in season one, Annie Mumolo in season two) – is a new character original to the show who is a female yellow duck and Daffy's girlfriend. Tina works at a copy store called "Copy Place". Tina is another straight character of the show, with a no-nonsense personality. Tina first starts dating Daffy because "Tina likes a project"; Tina tolerates his selfish and arrogant behavior as Tina has a keen astuteness which allows her to read between the lines when they first meet; Tina works out that Daffy is actually insecure and jealous, and that his vain attitude is really a front. Daffy is amazed Tina works this out so quickly and later reveals Tina, through email, that Daffy can't believe someone "so kind, beautiful, generous, and intelligent" would ever want to be with someone like him. After reading this, Tina is touched, and tells Daffy that she loves him. Tina is based on Melissa Duck from the original theatrical shorts. The character was originally called Marisol Mallard in the Laff Riot pilot.^[5]

Recurring

• Tasmanian Devil/Taz/Poochie (voiced by Jim Cummings) – is a male Tasmanian devil who is Bugs' pet. In this show, the Tasmanian Devil is portrayed as walking on four legs like a real Tasmanian devil and his eyes are bloodshot red (later turned back to yellow after Bugs uses a taming trick he learned from Speedy Gonzales). Initially, Bugs believed Taz to be a dog and kept him as a house pet named Poochie much to Daffy's discomfort. Eventually, Bugs learned the truth and tried to return him to his home in Tasmania only to find out that Taz would rather live with him. When Taz is not causing trouble for Daffy, Taz has occasionally tried to eat Sylvester. In the episode "Ridiculous Journey", Taz spoke for the first time in the series and had bonded with Sylvester and Tweety while they evaded Blacque Jacques Shellacque.

This series marked the final time Foray provided the voice of Granny before her death in 2017.

• Wile E. Coyote and the Road Runner (Road Runner is voiced by Paul Julian via archive recordings, Wile E. is mute) – are shown in short computer-animated segments in season one. They also make small cameos throughout the show, most notably in "Here Comes the Pig", when Bugs is lost in the desert, he witnesses one of Road Runner and Wile E.'s chases, then asks Wile E. for directions to the highway once he fails. Bugs then decides to use Wile E.'s catapult to get back.

Critical response

Critical response to The Looney Tunes Show was mixed. The voice acting, humor, portrayal of the characters, and style received praise, but the show was also criticized for its direction and lack of slapstick, as well as the designs and personality changes of the characters.^[2][16][3]

In a 2010 interview with CBC News, series animator Jessica Borutski said in response to fan criticism of the series' new character designs, that the original designs were intended for adults and that "[it is] time for a new generation to meet the characters."^[3] Borutski said, "a fresh, new design is the only way to keep characters alive."^[3] Cartoon historian Chris Robinson noted also that the mark the original characters have on fans is indelible and that fans are not receptive to change. "[Fans] just really become attached to these things," Robinson said. "It's just so strongly rooted in their childhood that they're unable to separate themselves."^[3]

Common Sense Media gave the series 4 out of 5 stars and the disclaimer: "Fun remake of classic toon has a more grown-up feel."^[17]

Awards and nominations

The Looney Tunes Show was nominated for three Primetime Emmy Awards.^[18]
