In a competition of speed between the Blue Blur and the Scarlet Speedster, it will take more than math and science to really comprehend their overall speed. However, taking all things we know into account,
Fans often wonder who is faster, Sonic or Flash. Whether it's Barry Allen or Wally West, The Flash is the fastest speedster in the DC universe.
Regarding regular videogame Sonic, there are claims that he can run at light speed. Superman has flown across galaxies in seconds multiple times. Best case scenario outliers for both characters: Here's Archie Sonic seemingly running at infinite speeds.
While Sonic is naturally fast and moves at the speed of light, the Speed Force is able to allow the Flash to become fast enough to travel through time and dimensions. As such, it is tough to say who between Sonic and the Flash is the faster one because they have different levels of speed.
The Flash was MUCH, MUCH faster than Sonic, but Sonic actually beat Flash in most categories, particularly Attack Potency and Durability. Boomstick: The gap in speed was huge, but Sonic's power and durability could certainly allow him to hold his own. At best, the Flash was Star level+ via the Infinite Mass Punch.
As the current Flash in DC Comics, Wally West is one of the fastest men alive, easily able to outpace people like Superman and manage to keep up with people like Barry Allen, but a long time ago Wally admitted that the Reverse Flash is much faster than him.
Super Sonic moves at the speed of light. Ssj Goku should move at the speed of light or faster. It's been confirmed that the higher your power level, the faster you are. That means Super Sonic and Ssj Goku are the same strength.
Quick Answer: Barry Allen may be known for his superspeed, but just how fast can he run? Unfortunately for fans, it's not quite the speed of light. According to The Flash, Allen's top speed is Mach 3.3, or 2,532 miles per hour.
By being able to travel in a dimension where time has been eliminated, Dragon Ball's Goku proves that he is technically faster than even the Flash.
His main strength lies in his super-speed, which he can apply in many ways. He can run at the speed of sound while coursing over water, buildings, and enemies alike. Sonic has immense control over his direction and momentum at such high speeds, making him an unpredictable fighter.
Sonic has spd measurements in sonic unleashed wit his highest being 3519 spd (or 6,051,022,551 mph) which is over 9 times faster than light, but even this isn't nearly as good as running through time to fix space in sonic generations.
HYPER sonic is indestructible, which means that he can wipe the floor with superman. And there's nothing he can do about it. The only thing he CAN do is find a way to detransform sonic. But apart from that, sonic CAN beat superman.
The two heroes have raced several times since then, in the comics, cartoons and movies. As a general rule, the comics claim that The Flash is the faster hero, with Barry Allen, Wally West and even an octogenarian Jay Garrick having outrun Superman over the years.
The Flash Has Always Been Faster Than Superman
The Flash is the Fastest Man Alive, and that includes being faster than Kryptonians. While Superman is powerful and a close second as the world's fastest hero, he can't top the Speed Force.
Robotnik provided him with "power sneakers" and allowed him to train on his "kinetic gyratoscope", resulting in Sonic being able to run at super-sonic speed.
Superhuman Speed: The Black Flash can move at vast superhuman speeds, easily keeping up with Barry Allen, and surpassing the speed of light.
Superman can fly at speeds almost equal to 2.6×106 m/s. A supersonic jet on the planet Krypton can fly at a maximum speed of 260000 m/s.
Goku has defeated many enemies just as powerful as Super Sonic, if not more powerful, and his mastery in martial arts means he can overpower Sonic in direct combat. And if the situation calls for it, Goku can use his Hakai to erase Sonic out of existence.
Mario's determination, strength, and willpower are unlike any human being, though, and given certain circumstances, Mario would easily beat Sonic. This is reliant on his power-ups, power of the elements, and his allies, though, while Sonic doesn't really need anything except his blinding speed.
Goku would win
In 2002, Wizard magazine covered the topic. Wizard concluded that Goku's power known as Super Saiyan would be strong enough to defeat Superman, with a planet-destroying punch being lethal for the latter.
