1) Bale Batman
2) Chen Zhen (Fist of legend)
3) Ip Man and the Northerner

He utterly demolishes Baleman and likely does the same for the next two, unarmored Spacemarines have feats for things like splattering normies with casual back hands, casually lifting several hundred kgs, sci fi style acid spit, moving faster than a normies can keep up with, etc

-An intermission here where he gets 1 hour break and now gets Power Armor-

3) MCU Falcon and MCU Winter Soldier
4) The Suicide Squad (2021 versions)
5) John Wick, James Bond, Jason Bourne, Bryan Mills (Taken), Jack Bauer (24), and K (Blade Runner 2049) all armed with pistols and knives

Astartes doesn't really need a breather given they have feats of continuous combat lasting days without any rest, regardless conventional bullets and knives aren't even scratching the paint on Astartes Ceramite so not seeing how this isn't even more of a curbstomp than the previous one

Cap's shield will work against a bolter the same way it works against everything else but he cant really hurt him, and given that I'd put an unarmored Astartes at the very least on par with Cap physically if not superior, a fully power armored Astartes should be dramatically physically superior to him
Black Panther should be roughly similar to Cap, maybe a big harder to get through his suit because of the kinetic thing but Thanos showed that can be overwhelmed, also still probably susceptible to things like a broken spine while wearing it. So same result if a bit more effort required
Neo's in the same boat as the previous tier, normal bullets aren't doing anything whatsoever, the Space Marine can actually sleep while he wears himself out trying to hurt him
first battle that might actually be an issue, never saw Venom but Pete's at the very least strong enough to do something here and mass webbing is always a possibility. Problem is that a Bolter will absolutely end him if he gets hit even once(also think Venom would be pretty susceptible to it from the little I've seen), also a combat knife is supposedly a monomolecular edged weapon so it might be perfectly effective against webbing. First battle that could go the other way
assuming he gets through it
Terran Marine is inferior to an Astartes in virtually every aspect, especially in mobility. Jensen as with Neo might as well be the previous tier and may as well not even be here. The Doom Slayer on the other hand... well I think the Slayer by himself is the first hard stop in the fight. Energy Weapons, Esoteric Weapons, BFG, his own physicality, the fact that he's, you know, the flipping Doom Slayer, etc
If he got past that somehow
Nameless joins the list of people who can't hurt him here

What if Nameless gets swapped out for Yulaw?

[Hiromi]

Space Marines havefeats for moving faster than normal humans can react to and reaction to things beyond what normal humans can see, and maybe into low level actual bullet time territory(namely fighting evenly against Eldar who explicitly did have bullet timing feats), but Yulaw if memory serves was a high end bullet timer, able to move and act extensively at bullet time speeds as well as having super human strength

One of the Horus Heresy books had an Eversor fight an Astartes, and he was out and out faster than the Astartes(while mainlining every single combat drug he had available at max quantity) and after every single weapon he had failed to get through the Marine's armor he finally managed to mortally wound the Astartes with his own combat knife(almost died doing it to), could see Yulaw duplicating that
