No.
Even ignoring the impossibility of Superman, the Hoover dam isn't strong enough to be lifted at one point, as Superman would have to do.
If he pulled at it from the top, he'd only pull a chunk out. If he pushed from the bottom, he'd only cut right in. It'd be like trying to lift a sand castle on a pitchfork.
Sure why not Superman would be able to handle the heat of the lightsaber!
Yes, I believe so. As long as the GL's will is strong, they would be able to beat Superman.
Just a regular ol' run of the mill vampire? Obviously Superman would win. The vampire wouldn't be able to bite Superman.
With his superstrength alone, he would be able to change the course of a river. So, yes. Superman isn't real
The Jedi, they would be able to use the force on Superman before he even got to them.
Yes he can. Spider-man would not be able to put the man of steel down either by kicking, punching or shooting spider weds on him. Superman kills him.
Would totally depend on the circumstances. Batman knows a great deal about Superman's weaknesses and could thus gain the upper-hand by exposing him to kryptonite or a red sun. The batman from the "Red son" storyline (Where superman was a communist) Batman was able to beat him using those weaknesses. However if Superman decides to fight batman without batman being able to prepare, superman would have won in about 1 picoseconds.
You can purchase Superman cuff links online at the Amazon web store. You can also purchase them from personal sellers using website such as eBay and Craigslist.
Batman if he has prep, (he soloed the entire JLA with prep). Superman in a random fight for obvious reasons such as him being FTL and able to rip apart planets.
This question is hard to answer. It has been shown that both have an incredible flight speed, apparantly being able to break the sound barrier, but it's hard to measure. Neo was able to create a vortex behind him in the second movie when he's trying to catch Trinity. Superman would be able to do something similar for Lois or anyone for that matter. The only thing that changes anything is how they get their speed. Superman gets his power from the sun, a fixed source, similar to a battery. Neo gets his from his mind, which is similar to an engine in that it can go faster if you give it more. But is that more powerful to beat the power of the sun? I think it can, but to do so would mean Neo's death. Therefore Superman would have a faster average speed but Neo would have a faster reachable speed.
1. You wouldn't have any electric 2. Nothing would happen as there is no air in space.
Never!!
