The number one superhero power would have to be flying. Every great superhero flies in one way or another. Superman was born with the ability and Ironman invented his suit.
While everyone's answer may differ, I believe the best power is superspeed, you can run on water, no one can catch you, and best of all you can enjoy carribean vacation in few minutes.
This debate has been going on since superheroes first came to be. Most superhero fans, though, will agree that super speed (like the Flash) is the number one power. A person who can run so fast that he can't be seen is virtually unstoppable. The possibilities for someone so fast he can't be stopped are almost endless.
i think spiderweb is the best superhero power because you can grab enimies with your web and punch them or you can swing them around or you can do a superspin slam with it and you can swing and launch your self in action with a super kick
It would have to be flying. If you're a superhero and you can't fly, you're definitely a second-tier superhero. Flying helps you get places fast, plus it is very cool.
The best super power would have to be telepathy. If you can read and control people's thoughts, there really is no limit to what you can accomplish. Of course, this also makes for a really powerful villian.
Invincibility is the best super power because then you can go anywhere and do anything and it won't matter. You don't have to be subtle because you can't die.
My favourite is superman. Because importantly he can fly, and the x-ray vision to see things through, and the power to lift huge weight and the power to stop anything which will harm. And importantly he can run faster and faster than anything.
Superhuman strength of some sort is probably the most common. The ability to move in a superhuman way -- such as fly or run super fast -- is also popular.
While obviously subject to personal opinion I would argue that the number one superpower is invincibility. While not as awesome as flight, you would not have to worry about anything.
The number one superhero power is flight. Superheros need an efficient way to get from point A to point B. Flight requires no gas or vehicle and allows for the element of surprise.
