Wolverine's dreams are so messed up as it is Freddy will want to check into therapy after he steps in... sure he already needs it but he will want to get it after this.
Jason vs. Collosus is an even worse match up then this one. Jason would be reduced to a fine past from one hit.
Also I'm not sure if Wolverine was scared of Cyber, rather Cyber had a drug that made people fear him... I think.
There was a story in the comics in which Wolverine went up against a creature called Nightmare who had similar dream-manipulation powers to Freddy. If Wolverine came out on top there, he could probably handle this one.
Plus, I think his typical reaction to fear is to get madder. He'd go into berserker mode, wake up, yanking Freddy into reality and then carve him up.
Freddy does have a comic actually he has alot i think at least 10 maybe more anyway yeah only in the dream world would he win probably wolverine could take out jason cutting his machete in half then his head off but still it would not be SUPER easy it would take alot of punking on freddy's part to beat Wolverine having to use his stealth and brains he did pretty good against jason dont know if that a comic but its canon since one comic is after the events of freddy vs jason its called nightmare on elm street special by avalon or avatar comics LOOK IT UP.
