The Sonic Show

What if the Sonic Boom TV show was a different TV show? Of course Rise of Lyric would still be the same game, but Sonic Boom would be a completely different TV show.

The Sonic Show (commonly known as Sonic 2016) is an American animated comedy action sitcom that aired on Cartoon Network from November 29, 2016 to August 31, 2019, based off the Sonic the Hedgehog franchise by Sega. The Sonic Show takes a more comedic and sitcom-like approach to the Sonic franchise. It chronicles the adventures of the titual title character (voiced by Roger Craig Smith since 2010) and his friends in the fictional town of Green Hill on South Island. As of 2019, the show's merchandise generated $1 billion for both Sega and Cartoon Network. The show had much popularity among Sonic fans. This is also the first Sonic TV series to be produced 11 years after the anime Sonic X. Throup Van Orman and Van Partible, well known members of the animation community created the show but from season 3 onwards, they quit and the show has now been run by Brendan Sawyer, known for working on the Netflix show The Boss Baby: Back in Business (2018-2020) and co-run by Jeff Fowler, who directed the Sonic movies (2020, 2022, 2024) and animation veteran Paul Rudish, creator of the Mickey Mouse shorts (2013-2019; 2020-2023). All three of the developers have stated that they loved working on the show including with the writers and animators especially. It has been described as "a safe working environment." The Sonic Show combines elements of comedy, slapstick, and sitcom, despite not having a laugh track like other animated sitcoms.

In February 2014, Sega of America announced that it would be teaming up with Cartoon Network to produce The Sonic Show, which was announced for release in late 2016. Roger Craig Smith and several other voice actors announced they would be reprising their roles as their characters while more information about the show was revealed, including about it being a sitcom, which made many fans skeptical of the show at first but Van Orman and Partible denied the fans' worries, saying that they'll make the show as great as it possibly can, like a combination of Seinfeld and Sonic. Ashton Kutcher was announced to star as Fang the Sniper, an obscure Sonic character from the 1990s, who would not be a villain in the show. Roger Craig Smith among several voice actors would be announced to reprise their roles as their titular characters including Mike Pollock as Doctor Eggman, a role Pollock has been playing since Sonic X in 2003. Production on the first season ended in February 2016 while production on the second season began in December of that same year. The show's first trailer was revealed in March 2016, and a lot of hype and anticipation was led up to the first episode of the show titled The Bowling Game.

The Sonic Show initially received mixed reviews from critics but in the years following its original premiere, it has received worldwide acclaim from critics, audiences, and fans of the Sonic franchise, praising it for its performances, dialouge, writing, animation, and humor. The show is considered to be one of the greatest television series of all time especially taking inspiration from Seinfield and ''Friends. The Sonic Show was originally created by Van Orman and Partible to rival another Cartoon Network show Teen Titans Go!,'' which took up all the ratings on the channel at the time. While the first season was a success in ratings being able to beat Teen Titans Go! for a short amount of time, the second season received lower ratings due to the network airing Teen Titans Go! more constantly compared to their other shows, causing it to get cancelled after its second season. After a massive spike in popularity one year after it was cancelled in 2019, Warner Bros. announced in 2020 that they had commisioned 15 more episodes of The Sonic Show to be released on their streaming service HBO Max. In 2023, the first episode of the third season titled They're Back was released, along with the entire third season in general. The show would later be renewed for more seasons, with many calling it the "HBO Max era."

The Sonic Show has received several awards and accolades as well as nominations. The They're Back episode made the show surpass Velma as the biggest premiere day of an animated TV show. As of 2022, Warner Bros. Discovery owns the rights to The Sonic Show, thus putting the first two seasons (named the "Cartoon Network era") on HBO Max, now renamed Max. In July 2024, a feature film titled Sonic Revelations was released as a Max original movie.

GUN builds a giant fan (if they can build a giant truck then they can build a giant fan) and unfreezes everyone, who is confused about what happened but are told that it is 2023. After much trouble, everybody goes back to their regular lives.

Sonic Revelations (2023)
In the HBO Max exclusive movie Sonic Revelations, Eggman, Orbot, and Cubot go up to Eggman's grandfather Gerald Robotnik's Space Colony ARK, the place where Shadow was born. While exploring the ARK, they find an secret room filled with three pods containing three different hedgehogs. Eggman opens them and they all wake up. The dark blue hedgehog is Quacksalver (Jason Griffith), who is not a hedgehog but a robot based on a hedgehog, similar to Metal Sonic. He uses his jet boots to fly and shoots lasers out of his eyes.. The black hedgehog is named Dusk (Chris Pratt), which his name is a synonym of Shadow. He has the power to create the power of illusion with a Chaos Emerald, calling it "Chaos Mirage" technique. The dark grey hedgehog who had not been introduced yet is named Terios the Hedgehog (David Humphrey), the original ultimate lifeform that Gerald created but he, Quacksalver, and Dusk, were all abandoned by Gerald after a deadly lab test which took the lives of 4 people.

Eggman dresses all three of them up in spray paint and sends them down to New York City to do crimes. In just four hours, Sonic the Hedgehog is wanted for seven counts of burglary and felony. Terios, Quacksalver, and Dusk escape in a black van with the license plate number "S0N1C". The president of the United Federations declares Sonic wanted and on the FBI's hitlist. At South Island, Sonic is having a picnic with Tails, Amy, and Knuckles when the FBI arrives on the island and places Sonic under arrested. He is booted off South Island by Mayor Naka and put into Jail Island, a remake of Prison Island, which exploded back in Sonic Adventure 2. Shadow the Hedgehog closely investigates the incident and sees that in a footage of the van escaping, there was another person disguised as Sonic there.

Shadow and Rouge, along with Omega, are determined to find out who framed Sonic. Sonic meanwhile is sent to Jail Island where he is sentenced to 5-10 years in prison. Wes Weasley is seen trying to get his life back together, trying to sell healthier versions of the formerly discontinued Chaos Cola, now named ChaoCola. Wes is sent an phone call by Eggman and Terios to work with them on the Space Colony ARK, which he happily accepts. Dusk comes and picks him up to the ARK, where Quacksalver asks Wes to capture Shadow with Eggman. Eggman denies this and tries to do it himself. Tails, Knuckles, and Amy try to go to Jail Island in order to free Sonic. They talk with the staff and sercurity there to see if they can bail him out, however there is no parole on Sonic's sentence. Eggman sends out Orbot and Cubot to capture Shadow but they do a terrible job. So Terios does it himself, having a stronger connection with Shadow. Shadow is revealed to be telekinetically linked to Terios, which makes sense when he senses Terios before he captures him. They ensue in an all out brawl in Central City before Terios gives the final blow to Shadow to the head and causing him to fall down in an alleyway. Terios takes an unconscious, bleeding Shadow all the way up to the Space Colony ARK, where he is taken care of by Dusk. Omega and Rouge worry where Shadow is, and try to find the clues where he last was. At night, Tails in his Walker mech and Knuckles break into Jail Island to free Sonic. While Tails shoots the GUN robots with his Walker, Knuckles goes and frees Sonic. The GUN robots prove too powerful for Tails' old aged Walker, which gets destroyed.

Before the GUN robots shoot Tails, Knuckles and Sonic save him. Human guards come as well and they all escape them. They are intercepted by Mighty, who is working a late night shift. However, Mighty makes an excuse that he fell and twisted his ankle. Amy is outside waiting on the Tornado, wondering why she is put out of all the fun when they come and escape Jail Island. Shadow wakes up on the Space Colony ARK and meets Terios, who tells him that he is his brother. Not knowing Terios' plan, Shadow starts to bond with him, Dusk, and Quacksalver but is skeptical of Eggman, who tries to act all nice and innocent. With spells, Terios and Dusk turn Shadow into an alternate version of himself, Nemesis Shadow. Nemesis Shadow is given the order by Terios and Eggman to betray Sonic and his friends. The plan with Terios, Dusk, Quacksalver, and Eggman is to dominate the world like Eggman had always wished for and turn it into the Eggman Empire. However, Terios, Dusk, and Quacksalver all have different opinions on this as they think that Earth should be their world, leading to non-alliances with all 4 of them. Mighty is fired from his job, causing Ray to get mad. However, Wes Weasley is being held hostage by Dusk. Mighty, Ray, and Wes are kidnapped by Dusk and bought to the Nevada Desert, Area 54 where Dusk plans to lure Sonic in to kill him. Sonic, Tails, Knuckles, and Amy are booted off of South Island by Mayor Naka and have no other choice but to stay hidden in Central City. They all are able to hide in an unoccupied apartment room in Central City. Sonic mopes about who was the one who kidnapped him while Tails and Knuckles try to find evidence that Sonic wasn't the one who robbed all those banks.

Amy is in the bathroom washing her hands after showering when Dusk comes in through the wall and kidnaps her, unbeknowst to Sonic, Tails, and Knuckles. Meanwhile, Nemesis Shadow continues to bond with Terios and to a lesser extent, Eggman. Amy is put into the Nevada Desert with Wes, Mighty, and Ray who are all sweaty. When Knuckles finally realizes that Amy is missing, Sonic gets a call from Dust, saying that if he doesn't come and get Amy as well as Wes, Mighty, and Ray in the next 24 hours in the Nevada Desert in Area 54, then they will all be dead. Police arrive at the apartment after a lady reported seeing Sonic, but they all manage to escape before the police arrive. Nemesis Shadow goes back down to South Island to find Rouge and Omega. Rouge is excited to see Shadow but is soon contradicted when Shadow starts fighting her and Omega. Rouge and Omega end up victorious but Nemesis Shadow goes away. Nemesis Shadow starts to wonder if he really is the ultimate lifeform, having flashbacks about Maria and Gerald Robotnik with Dusk, Quacksalver, and Terios all in tanks. On Eggman's base in Green Hill, GUN soldiers come and raid his lab, thinking that he had something to do with Sonic breaking out of jail. Terios fights off the GUN soldiers while Quacksalver helps Eggman escape. However, Terios and Quacksalver betray Eggman and go to dominate the world on their own, leaving Eggman to be arrested by the GUN soldiers. Knuckles is sent by Sonic and Tails with a mask back to South Island to warn Omega and Rouge that they must save Amy, Ray, Mighty, and Wes but Omega says that Shadow has turned on them.

Dusk takes all four of them to Area 54 where he ties them up. Amy prays that Sonic saves her, Wes is fearing for his life, and Mighty and Ray try to apologize to each other about the argument they had earlier. Sonic, Tails, Knuckles, Rouge, and Omega arrive at Area 54 and are able to get past sercurity, though Omega stays outside. They are able to find Wes, Amy, Mighty, and Ray and before they untie them, Dusk comes and an battle ensues. Wes and Ray escape and they are able to get a secret tape from Dusk's insides after Sonic punches him. They put a tape into an old TV, where Gerald Robotnik reveals "Project Robotnik", an operation that was originally created by Gerald in April 1951 to help humanity and Maria, for the better. The tape that Gerald documents reveals the horrors of Project Robotnik. After a deadly experiment that killed four people and caused Gerald and other scientist to get into a wrongful death lawsuit, Gerald discontinued Project Robotnik and two months late, Shadow the Hedgehog was born surrogate on June 19, 1951 and even shows footage of Maria meeting Shadow for the first time. In another flashback, Shadow sees Gerald talking to scientists with Dusk, Quacksalver, and Terios in tanks filled with green liquid but Maria pulls him back, saying that Gerald would be mad if they had been evesdropping on him. Wes and Ray mourn about this while Sonic, Tails, Knuckles, Amy, Rouge, Omega, and Mighty fight off Dusk. Omega is able to knock off Dusk, causing his power to go out. The seven all celebrate but it is interrupted when somebody starts kicking down a door. They all prepare if it is guards, but Terios and Nemesis Shadow are kicking down the door.

For 10 minutes, they all have a battle with Wes and Ray trying to have an artifical intelligence program to help them. Even though they all get beaten up ruthlessly by the two, Sonic goes all out on Terios, blaming him for getting him put in Jail Island. On Jail Island, Eggman is freed by several of his badniks from Sonic the Hedgehog '06. Eggman goes back to South Island and gets his equipment and badniks ready to go and get revenge on Terios, Quacksalver, and Dusk. Nemesis Shadow and Terios leave, taking Amy, Mighty, and Ray with them (Ray after he tries to save Mighty), and they all mourn with their efforts having been wasted. Wes tries to cheer them up but Knuckles has an idea. Wes confirms that he heard Eggman was betrayed by the three of them. Before they leave to South Island again, Dusk mentions that he was bullied relentlessly by Quacksalver and Terios on the Space Colony ARK back in 1951, and wants to get revenge on the both of them, and make them suffer. In that, Dusk also joins the team. In Eggman's lair, Eggman plays "E.G.G.M.A.N." while he, Orbot, Cubot, and their other badniks get prepared for battle. That is until Sonic, Tails, and Knuckles show up. Sonic (unhappily) announces that them and Eggman need to team up to stop Terios. Sonic is reluctant at first, but Tails reassures him, saying that whether he likes it or not, Terios and Quacksalver are going to dominate the world and enslave all life on the planet, so they must enlist help from Eggman since he has more equipment they can use. And like that, Sonic, the others, and Eggman all team up together. Eggman announces that earlier he placed a tracking device on Quacksalver, and with that they can determine where they are going. Nemesis Shadow, Terios, and Quacksalver all travel to the

Wave is the most intelligent of the trio and has an IQ of 320, easily surpassing Tails and Eggman's IQs of 253 and 254, respectively. Wave's father was apart of the previous generation of the Babylon Rouges, and continues to pass on his legacy.
 * Omochao (voiced by Laura Bailey in 2016, Erica Lindbeck from 2016-) - is a robotic Chao with a propeller on its head. Omochao is a robot created by Tails that serves as a "guide instructor" for people. Many (almost every) people on South Island hate Omochao because of how "obvious it is."

Metal Sonic occasionally appears to fight Sonic, but usually ends up losing. Metal Sonic at the end of season 2 turns into Metal Overlord but is defeated by Hyper Sonic, Hyper Tails, and Hyper Knuckles.

Conception and writing
Back in 2002, one year after Sega left the console market and became third-party developers, Craig McCracken and Lauren Faust pitched the idea of a Sonic TV show to Sega of America, with Faust and McCracken working on the show alongside Foster's Home for Imaginary Friends. The show would have aired on Disney Channel and would have lasted for four seasons, with 26 episodes in each and 104 episodes in total. The series was surprisingly able to make it far, even having an entire pilot made titled The Sonic Show, taking a Seinfield sitcom approach which the later show would inspire. However, McCracken and Faust found it difficult to work on the show at the same time and thus abandoned the show. Unable to find someone else to take the helm, Sega abandoned the project. In 2017, the pilot was found and dumped online. According to the former voice actors of Sonic and Knuckles Ryan Drummond and Scott Dreier, the show would have featured the voices of Drummond and Dreier as Sonic and Knuckles respectively, Jennifer Douillard as Amy Rose, Deem Bristow as Doctor Eggman, and Tara Strong providing the voice for Tails replacing Connor Bringas from Sonic Adventure 2. According to David Humphrey, Shadow would have also make an appearance in the show. In 2005, Sonic X (2003-2005) had aired its third and final season in Japan and in the US on 4Kids. Takashi lizuka, head of the company that makes the Sonic games Sonic Team had pitched to Sega an idea of another TV show following the canon timeline of the games like a fourth season of Sonic X or a seperate television series, even adapting the story of Sonic the Hedgehog (2006). While Sega and Sonic Team adored the idea, 4Kids were not interested in making another TV show based off Sonic, so lizuka tried pitching it to other networks such as Fox, MTV, and even Adult Swim at one point, but all networks refused the idea of a Sonic television series, with some considering that Sonic X was the perfect place to end a Sonic TV series, as even 4Kids thought so. In 2006, Sega and lizuka completely abandoned the idea of a new Sonic TV show, and had thrown the script in the garbage, literally by Sega executives at the time.

In 2013, The Marvelous Misadventures of Flapjack (2008-2010) creator Throup Van Orman expressed interest in adapting a TV show based off the Sonic the Hedgehog property. Van Orman stated that the interest in the show after playing Sonic Unleashed (2008) and Sonic Generations (2011), as well as watching the television animated DiC series Adventures of Sonic the Hedgehog (1993), seeing potential in a slapstick like Sonic show. Van Orman did not pitch the show to Sega of America until October 2014 where he reportedly was recorded entering Sega of America headquarters with a 15-page script in his hand. After that, Van Orman announced on his DeviantArt that Sega had approved of the show and announced that production would start shortly after the release of Sonic Boom Rise of Lyric (2014). After Sonic Boom: Rise of Lyric released in November of that same year (to obviously generally negative reviews), Cartoon Network Studios and Sega announced a collaboration between each other to produce the first Sonic television series since Sonic X 9 years ago, to premiere in mid-to-late 2016 on Cartoon Network, with Van Partible, creator of another Cartoon Network show Johnny Bravo (1997-2004), also announced to co-create. The first thing that began with production was the writing on the episodes. At first, the series was given the codename Sonic: The Series, but was then renamed The Sonic Show. Van Orman and Partible hired several well known members of the animation community to work on The Sonic Show. These included Kent Osborne who worked with Van Orman on Flapjack and also worked on SpongeBob SquarePants (1999-present), Craig McCracken the creator of The Powerpuff Girls (1998-2005), Daron Nefcy who would go on to create Star vs. the Forces of Evil (2015-2019), Paul Rudish, the developer of the Mickey Mouse shorts (2013-2019, 2020-2023), Lauren Faust, wife of McCracken and creator of My Little Pony: Friendship is Magic (2010-2019), Chris Savino, creator of The Loud House (2016-present), animation partners Spike Brandt and Tony Cervone known for their work with Warner Bros. Animation and who also directed the 2002 pilot, Craig Bartlett, creator of Hey Arnold! (1996-2004), Aaron Springer, creator of Billy Dilley's Super-Duper Subterranean Summer (2017) who also worked on SpongeBob, and Clayton McKenzie Morrow, who worked with Rudish on the Mickey Mouse shorts. All eleven writers were able to write all 26 episodes of the first season in three months. Partible and Van Orman also helped with some episodes, with Van Orman writing and directing the first episode.

South Island was going to be shown like how it was in the 8-bit Sonic the Hedgehog game in between levels, but after writer Kent Osborne jokingly asked AI to make a picture of South Island, Chris Savino absolutely love the results so he and Brandt drew a more different version of South Island. The drawing on the side was made by AI. The actual drawing Savino and Brandt made was used for the show. In season 3 of the show, South Island was given many more locations, each of these locations being based on actual locations from the IDW comics. Ian Flynn was promoted to writer in season 3, along with 2001-09 Sonic writer Shiro Maekawa and famous duo Phil Lord and Christopher Miller. Writing lasted for three months with all 26 episodes completed on February 19, 2015 after Partible announced the show had finished its writing stage.

After the writing, production on the show officially began.

Casting
Roger Craig Smith announced he would be reprising his role as Sonic the Hedgehog in the show in April 2015. Van Orman and Partible wanted Kate Higgins to reprise her role as Miles "Tails" Prower after she was replaced by Colleen O'Shaughnessey in Rise of Lyric as well as Sonic Boom: Shattered Crystal. But they later changed their mind and went for O'Shaughnessey. Mike Pollock and Cindy Robinson announced the reprisal of Doctor Eggman and Amy Rose, respectively. Travis Willingham and Kirk Thornton were announced to as Knuckles the Echidna and Shadow the Hedgehog with Thornthon reprising his role as Orbot and Wally Wingert as Cubot, Eggman's henchmen who first appeared in Sonic Colors (2010). Fang the Sniper, an incredibly obscure Sonic character who only appeared in Sonic the Hedgehog: Triple Trouble (1994) and Sonic the Fighters (1996).
