Super villains would beat super heroes in a fight if all were involved at once

First ill address my opponents arguments First off i would like to show that Superman can die as shown in the Death of Superman comic book story line. Though he is almost immortal he may choose to live or die as he pleases, because of his humanoid up bringing Superman believes in fate and if he was to die he would accept it and die. Superman is also able to be wounded/ killed by other Kryptonians and Magic. Secondly you say " I mean we all know the hero always win in the movies so its basically the same thing. Mostly all of the super villains have been beaten in all of the movies or comic etc. " There are movies in which the hero is defeated, for instance there was a mortal Kombat movie (which my apologies but i can not remember the title) in which by the end of the movie Shang Tsung had defeated all the Earth Realm fighters. Also I would like to include the fact that In the Batman series there are countless of times in which The villain The Joker has the chance to kill Batman but chooses not to for the fact that if there is no Batman, The Joker would have no one to "play" with. Resources . http://batman.wikia.com... (third paragraph under character it refers to the many times Joker has given up chances to kill Batman) . http://dc.wikia.com...(Clark_Kent) #Death_and_Return (first two paragraphs of "Death and return" give information on Supermans death and rebirth so to say) Now i'd like to make my own argument. Firstly, The best chance that the Super heroes have is Superman can we both agree on that? If so then i would like to pit Superman against Freddy Krueger. First i would like to mention the fact that the only way to be able to fight Freddy is to go into his dimension "The Dream world" where once there, all current earth dimension rules do not apply, it is Freddy's turf and he decides who is able to do what. This means once there Superman will be bent to Freddy's very will. There is also only one person who is able to completely kill Freddy who is his daughter Maggie Burroughs. Although Superman may have the advantage in the normal reality the only way for him to get Freddy there is for him to enter Freddy's dream land. Freddy shares a few power/abilities with Superman including; 1. Super human strength 2. Super human Durability 3. Accelerated healing powers With this in mind we see that within Freddy's Dream world he is not able to be killed, this also extends into the real world where in the only way to kill him is to release the dream demons from within him, in which only his daughter has been capable of doing and knowing how to do. . http://horror-movies.wikia.com... . http://nightmareonelmstreet.wikia.com... Sencondly, Jason Voorhees is the second character i wish to bring to the fight! Jason Voorhees as everyone should know is the camp crystal lake killer. he is able to use both ranged and melee weapons VERY efficiently. Though like Freddy he is able to be killed (in the physical sense). If Jason's physical body is destroyed his evil spirit still remains and is absorbed by anyone near his heart after he is killed. Though Jason has been killed multiple times it should be noted that every time he is resurrected he comes back stronger and smarter then before. I am already enjoying this debate and can not wait for my opponents reply.
