Yes
The smol boi, Kirby
Can you count more characters that aren't comic characters? Like seriously, who won't expect comic characters to fill like... 93% of the people that can beat Doomslayer? Also, I haven't watched Nightmare on Elm Street, but I'm pretty sure Freddy couldn't kill Doomslayer because Doomslayer never sleeps
As for the person above that, idk if SCP 682 could beat Doomslayer, Its a lizard with regenerative abilities and calling it god is I'm sure highballing it
682 isn't god, but every single thing the foundation tried failed to kill it. It even came back from being thrown into the sun.
It also survived an encounter with 001, a being that not even Doomguy would beat.
Doomguy stands no chance against 682, as it'll adapt to everything Doomguy has to offer.
In the scenario where Doomguy falls asleep, the only defense he has against Freddy is waking up. If he can't, then you better hope he can lucid dream.
I only listed characters that come to mind. Here are some more:
Darth Vader
Probably Predator
Pennywise
Godzilla
King Ghidorah
Peter Griffin (not serious)
Tbh, i do really think Doomslayer beats 682, he can tank weapon way hotter tan the sun straight to th face, stayed in hell for eons, killed god, defeated sin, etc. As for surviving 001, im gonna assume you mean the safe class one, the giant sword wielding angel that guards the door to heaven or summin. idk if doomslayer beat that guy, but its prolly safe to assume hed surive an encounter with it.
I still am a bit unsure about Freddy, i dont think he can make doomslayer fall asleep.
And i agree with everyone you listed except Predator. he got defeated by some soldier, i dont think he'd beat Doomslayer at all. And Pennywise too, since last time i remember, his power comes from the fears of his enemy, and im pretty sure Doomslayer doesnt fear anything.
Here's an joke option, chantel dubois from Madagascar 3
She can obliterate Doomguy with her unmatched skills. (In all seriousness, SHE will be obliterated.)
[REDACTED]
A titan cyberdemon
Aizen and Yhwach from Bleach
