How powerful would Composite Horror Slasher Villain be?

(Alien, Predators, Jason, Michael, Leatherface....Paul Bunyan.)

Probably virtually anything that sleeps and isn't fairly psychic, what with the whole Freddy Krueger thing letting them set dreams up where the victim doesn't have access to their usual power levels.

And that's just with Freddy, I assume. With all the high-end Horror Slasher villains added into the mix, it's going to take somewhat strong levels of cosmic plot devicery to beat them?

Having watched Brightburn, Brandon Breyers alone is around Shazam characters, crucially bringing actual super speed to the mix, not just teleporting/portalling stuff (assuming people like Wesker and Isaacs from Resident Evil movies count closer to action movie villains).

In the Arena or in a PIS-less scenario?

In the Arena, between high end regeneration, and Breyers durability, it would take something in the neighborhood of class 70-80-ish superspeed brick to maybe put it down for a 10 count via speedblitz. It that fails, the composite is just going to go intangible. Since the composite consists of stuff like ghosts and demons, it's debatable if it can be killed via purely physical attacks. It can also teleport, even across dimensions, so the only things that are likely to stick is stuff that kills ghosts.

In a PIS-less scenario, where it has to go around killing everything in a universe, you have a reality warping monster that doesn't need to exist in the physical plane to attack people, and basically can't be killed with conventional weapons or attacks. You'd need a universe with fairly high end metaphysical beings/cosmics to stop them. Comic book universes like Marvel and DC are obviously way too high, and in a class of their own.

Most advantageous matchups are against universes that don't have ways to take out this sort of thing. Common Shonen universes, like One Piece, FOTN, One Punch Man, and so on. They're really strong, but have no counter to being attacked in dreams, for example.

Considering this is a horror composite, something like an urban fantasy world might be a thematically interesting matchup against it.

So...Dresden files universe would be too much for it. We can go lower.

Supernatural universe, with high end characters including stuff like the archangels, might be one of the weakest urban fantasy settings that the composite can't eventually solo in a PIS-less scenario. High end supernatural characters aren't exactly weak though, so we can probably go lower.
