Another possibility is that a character from Glee, say Rachel Berry, discovers she has some sort of meta - human ability similar to the Flash. The Flash has to come and train her to control it while also dealing with the chaos that her new powers cause within the glee club dynamic.
Well, one possibility could be that they team up to fight a common enemy from another dimension. Maybe a powerful villain who can manipulate time and space, which would be a great threat to both Superman's Metropolis and Flash's Central City. This would force them to combine their unique powers. Superman's super strength and flight, along with Flash's super speed, could create some really cool battle scenes.
No, The Flash doesn't reach the speed of light in Superman comic #709. His speed is usually depicted within a certain range that doesn't quite match the speed of light.
Brightburn's powers are similar to Superman's but with a malevolent twist. When they interact, it could be that their super strength clashes in a way that causes massive destruction around them. Their flight could lead to high - speed aerial battles, with each trying to outmaneuver the other. And their heat vision could cross, creating intense energy bursts.
Superman's powers are mainly based on his Kryptonian physiology, like super strength, heat vision, and flight. Flash's power is super speed. If they were to interact, Flash could use his speed to create distractions while Superman takes on the more powerful foes directly. For example, Flash could run around an enemy so fast that it creates a mini - tornado, and then Superman could use his super breath to blow the enemy into a vulnerable position.
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.
In a spiderman meets superman fanfiction, they might start as rivals. Maybe they misunderstand each other's intentions at first. For example, Superman could misinterpret Spider - Man's web - slinging in the city as some sort of unregulated vigilante behavior. But then, they would realize they have a common goal, like saving the world from a powerful villain. They could combine their powers, Superman's super strength and flight with Spider - Man's agility and web - shooting, to defeat the bad guy in an epic battle.
In a 'raven meets superman fanfiction', it could start with Raven sensing a strange energy signature which turns out to be Superman. She's intrigued and decides to observe him from afar.

They might then go on an adventure to stop an interdimensional threat that only their combined powers can handle.
