Freddy Krueger Vs Joker
Freddy in his comics appearances is portrayed same as the movies, which is to say, pretty powerful. But can he really go up against the Joker??? PREDCNU Joker. Stats for both below, pics above because they looked cool...
FREDDY
While his "avatar" was dreaming, Freddy could control their dreams to his whim, manipulating them to his liking. Any physical harm done on a person in their dream would become a reality and carry on into their real lives. For example, if he cut a person's stomach, when that person woke up he/she would have cuts on their stomach. With this ability, it's easy for him to commit numerous murders, hence why he has harmed and killed multiple people. Freddy constantly plays with his victims appearance and his surroundings, most often resembling their real world home. His powers increased at the rate of kids believing he existed. At his prime, he could cause critical damage in the real world. Among this variety of options included possession of humans. If Freddy is in close contact with someone he's affecting, (i.e, choking someone in their sleep etc.), Freddy comes into the real world along with his victim where he has superhuman strength and durability.
In his victim's dreams, Freddy could use their fears and personalities against them. A few of his victims somehow managed to use their imagination to manipulate their dreams to battle him. Another of Freddy's powers included absorbing the souls of his victim which increased his already high power. A mark of this is their faces on his chest.
JOKER
Due to his mental state, the Joker is immune to fear as he does not understand the concept and sees everything as a joke. He also has an immunity to poison due to prolonged exposure to chemicals. The Scarecrow's fear gas has no effect on him, and Visionary failed to hypnotize him. He and Poison Ivy have shown immunity to each others' chemicals. He possesses a very high tolerance for pain. Bullets seem to do little more than slow him down or put him out of commission temporarily. On several occasions, he has been known to survive explosions and crashes. His bones heal quickly, and it has been hinted that he does not physically age.
The Joker is a genius inventor and chemist. He has managed to create an MO which fits his macabre appearance. The Joker is immune to his own venom as well as various similar toxins. The Joker is an excellent marksman. The Joker has occasionally demonstrated above average hand to hand combat skills.
The Joker does not possess any outright super-human powers; however, It is suggested that he is "super-sane;" this means that he sees how the universe really is, without any personal illusions, and that his entire personality can alter to fit the circumstances, making him excellent at impersonating and lying as he truly believes what he says. He has the great strength that madmen are often said to have, and is quite agile.
It is debatable if it classifies as a super power or not, but the Joker's insanity, or his frame of mind, leaves him immune to the Spectre's judgement. Both Jim Corrigan and Hal Jordan Spectres have had major problems with navigating the Joker's mind.
