- The characters are misled into believing that one of the teens is Freddy's long-lost child, but it really turns out that it's their adult therapist. However, they'd seen newspaper clippings that documented when Freddy's arrest and lynch-mob demise took place, which ought to have given them a good idea of the age of his kid. So why didn't anyone notice that their initial candidate was a dozen-odd years too young to have been K. Krueger? Especially given that the film takes place "ten years from now" (i.e. from when the viewer watches the film), meaning that by now he's too young to have been conceived before Freddy's death.
- Not necessarily. Freddy is shown in a few movies to have a desire for rape. They could've just not ruled out the possibility he raped someone to conceive his child after his death.
- The dates in the classroom were all over the place (1493-Freddy sailed across the sea, 1869- Freddy kills Marie) he might just assume that the date (1966-Child taken) is wrong as well.
- It was established in Part 3 that Freddy could only invade the dreams of the children of the lynch mob. In Part 4 and 5 the only way Freddy could attack anyone else was by proxy in Alice's (and later Jacob's) dreams. So how in the hell did Freddy somehow kill every single kid in Springwood?
- Technically, it was in ten years that he was able to pull a feat like that. Its possibly that the reason why Freddy was strong in FD was because A) he had a long time to this and B) he can invade dreams and kill people. ''Freddy's Revenge'' shown that he didn't need the lynch children anymore in order to attack, when proclaimed that the teens at the party were all his children now. Freddy can attack teenagers in their sleep, thus making Springwood into a ghost town by FD.
- Freddy's Revenge was an outlier in that regard. Dream Warriors re-established Freddy's ability to only target the Elm Street kids. It was only after Alice inherited Kristen's power (which, we can assume, was corrupted when that energy passed through him before reaching her) that he was able to touch anybody else, since Alice's dreams would bring them right to him. Freddy's entire plan in Part 5 was for the very reason that he needed an intermediary (Jacob) to continue killing. FD pretty much seemed to retcon that plot point entirely.
- Always assumed Freddy could go into anyone's dreams, but just went after the children of those who killed him first. The only reason he needed Alice and Jacob in The Dream Master and The Dream Child was because he was weak and contained, and needed to act through them.
- The theory that Freddy vs. Jason is an interquel between Dream Child and Freddy's Dead got me to thinking about this one. Freddy can only go after people who know and are afraid of him in that movie but, apart from Nancy briefly referring to the idea in the first movie, that didn't really seem to hold in the other movies. Maybe that rule's a new tactic on his part. He always fed on fear, but he didn't originally need it. At first, his dream-stalking rules confined him to the Elm Street kids. Once they'd died, he needed Alice's powers to get around them and keep killing and, when he lost her, he used Jacob instead. When he lost both of them, he had to find another way out, and that's when he figured out that he could spread through people's fear of him. But the parents also realized that, and they managed to cover up his existence completely for awhile, which kept the town safe. But then Freddy vs. Jason happened and, since now so many of the Springwood kids know about Freddy again (and every new victim just adds to the domino effect), things quickly fell apart and the town was decimated.
- The Your Mind Makes It Real loophole he used to come back and kill anyone he liked in an area that's afraid of him was not just some brand new sudden Ass Pull: Joey explicitly brings up the possibility in Part IV.
- As for Freddy's Revenge, per Word of God, after his defeat in the first movie, Freddy's spirit was confined to 1428 Elm Street, where he was able to possess Jesse and go after whoever he wanted using him as the conduit. His defeat at the end of that film freed him from the house but put the "Elm Street kids" restriction back on him, leading into Dream Warriors.
- Technically, it was in ten years that he was able to pull a feat like that. Its possibly that the reason why Freddy was strong in FD was because A) he had a long time to this and B) he can invade dreams and kill people. ''Freddy's Revenge'' shown that he didn't need the lynch children anymore in order to attack, when proclaimed that the teens at the party were all his children now.
