Well, it's not straightforward to say. Different comics might portray their speeds differently based on the plot and creative decisions. So, it varies.
The comic Flash typically has more established feats of speed compared to the DCEU version. However, different versions and story arcs can sometimes make the comparison less straightforward.
In the movie Justice League, Superhuman and Flash both pursued their own goals, but their speeds were different.
Superman has superhuman speed that can exceed the speed of light, so he can move quickly and attack the enemy in battle. However, superman's speed also brought some limitations. For example, he could not stay in one place for a long time or move to certain places quickly.
The Flash had even faster movement speed. He could use his superpower to move faster than light. The Flash can also use his speed to teleport to other places in an instant, allowing him to quickly deal with different challenges.
Therefore, the speed of Superman and the Flash in the movie varied in different scenes. In some situations, Superman might be faster than the Flash, such as in battle; in other situations, the Flash might be faster than Superman, such as through teleportation technology.
Since it's about Sonic, Sonic himself is most likely a main character. There might also be his friends like Tails and Knuckles who would be involved in the story.
In the end-credits of the movie Justice League, Superman and the Flash were both running at high speed, but there was no obvious difference in speed. Because the Easter egg showed the abilities and performances of the two superheroes in different situations, it could not be simply compared.
In the movie, Superman had super strength and speed that could easily surpass the speed of light, so he could run fast. The Flash, on the other hand, had the ability to move faster than the speed of light. He could also think faster and react faster, so he could run very quickly.
In the Easter egg, Superman and the Flash both displayed their strength and skills, but there was no comparison of speed.
I'm not sure specifically as there could be many different interpretations of a 'dark sonic flash story'. It might involve a dark or edgy version of Sonic in a fast - paced and perhaps mysterious plot.
It depends on the specific fanfiction. In some versions, Sonic might have a brother or sister that the creator has made up for the story. It could be a super - fast sibling like Sonic himself, or one with a different but equally cool power.
There might be a wise old grandfather in Sonic's family. He could be the one who knows all the family secrets and ancient techniques. And there could also be some younger siblings, like a little brother or sister who looks up to Sonic and wants to be just like him. They could all have different personalities, for example, the older sister could be really strict but also very protective, while the younger siblings could be full of energy and curiosity.
