In 2012, Ken Balough announced that Big the Cat would be retired from the franchise (for the time being) as they could not find a good use for the character, and all things that they already tried didn't work out for him. This however did not stop Big from having a cameo in Sonic & All-Stars Racing Transformed, having a trophy in the 3DS version of Super Smash Bros. 4, and being playable in Sonic Runners.

Early in the process of proposing a design for the protagonist of the series, before Sonic as a hedgehog was considered, Naoto Ohshima considered having the protagonist be a human boy.
There was almost going to be a Sonic game based on skateboarding made for the Xbox, GameCube, and PlayStation 2 called Sonic Xtreme (not to be confused with the cancelled Sega Saturn game of the same name). This game was developed by a San Diego company called Vision Scape Interactive.

Development began in 2003 shortly after Vision Scape finished up Bare Knuckled Grind. The game was initially planned to be ported to other consoles. There were also going to other skateboarding games using the same engine, but with different intellectual properties, including the Nickelodeon TV show Rocket Power. Unfortunately, budget issues is what resulted in all 13 projects cancelled. They later worked on cutscene animations for Sonic Heroes, and later pitched to Sega the Sonic X-Treme prototype.

The prototype was finished in a week, and originally had planned to use hoverboards. The player would be to race against Sonic or Shadow. Yuji Naka, former head of SEGA, was impressed at the time and asked Vision Scape to make design documents for the game. However, when they did show the documents to SEGA, they went silent.

Later on, in September 2005, Sonic Riders was announced. People at Vision Scape believed that SEGA took some of the concept from Sonic X-Treme. and used it for Sonic Runners. However, legal issues from SEGA forced Vision Scape to shut down in 2006.

As a result of a sponsorship deal between the motor racing circuit Donington Park in Leicestershire, England and SEGA, the 1993 European Grand Prix was adorned with SEGA logos. Even the race itself was renamed the SEGA European Grand Prix.

Ayrton Senna won the rain-drenched event after passing four cars on the first lap and holding off his teammate Alain Prost through the race's length, and was presented a trophy which featured Sonic the Hedgehog. While the image of Senna holding this trophy was widely circulated around the Internet, it was unfortunately only a fake trophy used for a photo op. It's unknown what became of the Sonic trophy.

Silver the Hedgehog was originally going to be an orange mink named Venice, but the developers decided against it and changed him into a hedgehog as they didn't think that a mink would fit in with the other characters.

In Super Mario World 2: Yoshi's Island, one of the game's enemies is named "Harry Hedgehog", a fast moving blue hedgehog. It's thought Harry Hedgehog may be a subtle reference to Sonic The Hedgehog.

Tomoya Ohtani, a recurring composer for the series, frequently samples a portion of the famous drum break from the song Amen, Brother by The Winstons. This portion can be heard in 'Vs. Orcan' and 'Skullian' from Sonic Colors, the extra boss theme 'Boss - Big Swell' from Sonic Rush Adventure, and 'Cool Edge Day' from Sonic Unleashed, just to name a few.

Since Sonic was very popular in English speaking countries, one of Sonic's quirks in Japan (performed by Junichi Kanemaru) is that he may speak English at times, unlike other characters.

According to the Archie comics, Sonic the Hedgehog's real name was originally "Olgilvie Maurice Hedgehog", and was meant to act as a part of a never-used plot. However, due to one of the comic writers leaving the staff, this concept was never touched upon, and was eventually retconned as Sonic legally changing his name at an early age, leaving his actual first name a mystery.

Fang the Sniper, called Nack the Weasel in the English release of Sonic Triple Trouble and various English-language comic books, originally wielded a realistic gun.

According to the Sonic Comic series, Sonic's speed and color are a result of a lab accident, which involved a hamster wheel and some sneakers. This somehow gave him blue fur and super speed. Sonic was supposedly a normal brown hedgehog until this accident took place.

Dr. Robotnik was created to be the opposite of Sonic, and to be the bad guy. During the development of the game, there was a growing debate between developers and environmentalists, and Robotnik was created to represent machinery and development, as apposed to Sonic, who represented the environment.

His egg shaped redesign came from Naoto ÅŒshima wanting to give the characters designs that were easy enough for kids to draw.

The design for Dr. Robotnik/Dr. Eggman was based on a caricature of Theodore Roosevelt in pajamas.

In the early Sonic games, The Chaos Emeralds appeared to be 'Emerald Cut'. Eventually, the emeralds in the series became 'Brilliant Cut'. In reality they should now be Chaos Diamonds, as a brilliant cut is reserved for diamonds.

In the 1990 arcade racing game Rad Mobile, there is an air freshener of Sonic that is hanging from the rear-view mirror. This marks the first time Sonic has ever made an appearance in a video game, which, interestingly enough, predates the release of Sonic the Hedgehog in 1991.

In "Sonic the Comic, issue #8, The Origins Of Sonic," Sonic was originally brown and very spiky. He had met Dr. Ivo Robotnik (known at the time as Dr. Ovi Kintobor) by finding his lab, and they had become friends. Dr. Kintobor performed experiments on Sonic's super speed, which helped him to run even faster, and with the aid of the Power Sneakers Dr Kintobor invented, it allowed him to run so fast that he broke the sound barrier, turning him into a more familiar blue form.

The balloon also popped on it's one and only flight by being pushed into a lamp post by strong gusts of wind, hurting a kid and a police officer on it's descent. Because of this the balloon was retired after one time.

In 2010, SEGA de-listed every single Sonic game with anything less than an average Metacritic score so that they could not be bought new at retail or downloaded from console-based online services. This was in order to increase the value of the franchise to prepare for a "comeback". Ironically, "Sonic Free Riders", released the very same year, has a below-average Metacritic score of 47 out of 100.

There are at least two cases of art plagiarized from deviantart.com appearing in Sonic games. A piece of art of Sonia was mistakenly added to Sonic & Sega All-Stars Racing, and some fanart that was made for a Sonic and the Black Knight contest turned out to be a replica of someone else's artwork. Sega apologized both times.
