I mean, yeah, pretty much what the rest said. Seems pretty stompish overall. Like, especially if Maki really scales to half of what is written in OP.
There is a nearly 7x difference in strength, and you cannot damage special cloth even if you are stronger than Karma (Reaper level power is required).
I mean, "skill advantage," you say, but based on what exactly? I'm not even gonna compare their combat intelligence, which Karma should be heads and shoulders above, with simply being the commander who gave Craig his first loss.
As for H2H skills, uh, skill debates are more up
@Creaturemaster971's alley (though he may be distancing himself from it these days), but I can try, just off the top of my head,
Picking up Karasuma's martial arts techniques by watching them in action a few times—which Karasuma could use to hold his own against The Reaper's unorthodox, use everything and anything to kill all combat skills—with which The Reaper stands at the top of the assassination game by a large margin—said profession is just full of ex-military men who've all improved themselves to inhumane extents and single-handedly gotten out of literal war even when they were largely outnumbered. And Karma perfectly applies this in a death battle scenario on his first try.
Being able to correctly deduce the power levels of complete strangers he first saw on his life by running simulations in his head while keeping the number and skill advantages and disadvantages in mind, concluding that fight at that time specifically would be the end of his, and later single-handedly planning the wipe-out of them.
Karma has analytical on his profile from Korosensei's statements
Just noticed that. He shouldn't have one; it wasn't accepted by anyone;
PartialPriority54 added it, I think.
he reads other people's moves to aimdodge anyway like he did with Grip in the anime and predicted his classmates' actions in their little war or anticipated Nagisa's clap stunner in their fight.
Reads others moves and aimdodges? I mean, I'd appreciate some elaboration, I don't really remember this. Though anticipating Nagisa's stun clap is hardly any feat, that's Nagisa's trump card that he uses almost every time he goes one-on-one, and Karma was expecting him to use even before the battle. Him countering it, as well as keeping with Nagisa's analytical prediction are better feats I'd say.
he is ranked 3rd in marksmanship which should put him roughly comparable to Rinka Hayami and Chiba, both of whom have sniping skills on par with professional assassins
Wasn't there something like four or five marksmanship rankings in the series? Long-distance shooting, ambushes, etc., which one did Karma get ranked 3rd in? 'Cuz Rinka and Chiba are portrayed as the clear-cut best gun people.
along with knockout gas to use at close range
That's something he picked up from Smog's defeat, used it once, and threw it away; he isn't gonna magically take one out of his pockets.
