Going fast is the defining characteristic of the titular blue blur in theSonic the Hedgehogmovie series, and here is how fast the character can actually run. TheSonic the Hedgehogmovies are all about speed, with the various characters like Tails, Knuckles, Shadow the Hedgehog, and even Doctor Robotnik getting the ability to move at inhuman speeds across the three films. However, the speed of thesecharacters cannot compare to that of Sonic the Hedgehog, and here is how fast the character can move in theSonic the Hedgehogmovie series and across the video game franchise.
AlthoughSonic is incredibly young in the firstSonic the Hedgehogmovie, the character has already shown himself to be incredibly powerful, taking down massive threats like Doctor Robotnik at only 14 years old. Now that he is 15 inSonic the Hedgehog 3, Sonic will have to face an even bigger threat. Not only will the blue blur have to take on Ivo Robotnik once again,but Gerald Robotnik and Keanu Reeves' Shadow the Hedgehog as well. Sonic will have to move faster than ever to take these foes down, causing many to wonder how fast he can go.

Sonic The Hedgehog’s Speed Is Clocked At 300 MPH In The First Movie
But This Is Just The Start
The originalSonic the Hedgehogimmediately answers the question of how fast Sonic can go, with one of the film’s very first scenes putting an exact number on this. At one point,Sonic runs by a police car containing Tom Wachowski, who would go on to become Sonic’s father figure. Tom manages to use the radar gun on Sonic while he runs past, revealing that Sonic is moving at a whopping 300 miles per hour. Some of the world’s fastest cars have only barely made it over 300 miles per hour, highlighting how fast Sonic is moving.
Sonic The Hedgehog’s G.U.N. Organization: Backstory, Shadow Connection & More Explained
The Guardian Unit of Nations will play a major role in Sonic the Hedgehog 3, and here is everything that we know about G.U.N. in the movie series.
WhileSonic’s 300 mph speed may seem incomprehensible, this may only be the tip of the iceberg when it comes to how fast Sonic can move. Sonic is incredibly young in the firstSonic the Hedgehogmovie, and since he is faster than he was as a child, it makes sense that he will continue to speed up as he ages. After all, the character’s Super Sonic form inSonic the Hedgehog 2most likely allowed him to move faster than he could at his base level, and according to other franchise media, 300 mph is nothing for Sonic.

Sonic The Hedgehog Runs Faster Than The Speed Of Light In The Video Games
But He Can Go Even Faster
Although this hasn’t yet been proven intheSonic the Hedgehogmovie series, in the video game series, Sonic has been able to run faster than the speed of light. This is according to the video gameSonic Heroes, in which Sonic has an ability known as the Light Speed Dash. As the name implies, this move allows Sonic to move at the speed of light, which is around 670,616,629 miles per hour. This is obviously much faster than the 300 miles per hour speed that Sonic reaches in the first movie, showing that Sonic has a lot of potential left in him.
OneSonic the Hedgehogfan did the math and, according toSonic Unleashed, Sonic can run far faster than the speed of light (viaReddit). TheSonic Unleashedmanual already confirms that Sonic can move at faster than the speed of light, but an in-game speed measurement system allowed this Reddit user to measure by how much Sonic can exceed the speed of light. According to the math,Sonic’s top speed is 6,051,022,551 mph, which is around nine times the speed of light.

Sonic The Hedgehog May Have Unlimited Speed
According To The Laws Of Physics
Over nine times the speed of light seems to be the top speed of Sonic the Hedgehog at this point, but as it turns out, the character may have unlimited speed. According to the laws of physics,an object that moves fast enough has the potential to bend time and space, essentially allowing that object to time travel. Thus, if Sonic were able to do this, he could forego time and be anywhere he wants instantly.
Sonic The Hedgehog 3: Everything You Need To Know
Paramount turned Sonic’s live-action adventures into a trilogy with Sonic The Hedgehog 3 - including introducing a key rival from the games.
Luckily, Sonic the Hedgehog has actually done this. Time travel has been included in several of the franchise’s games, but inSonic CD, Sonic is able to run through time. Although this power hasn’t been shown off in theSonic the Hedgehogmovies yet, it would be an incredibly cool addition to a future sequel.
