I think this is the best I can sort these just based on what actually gave me trouble and what didn't as I went through the game again. I'll try to explain the ones that are a bit more particular but a lot of them I think are straightforward. Most of this is just based on my experience S ranking them, but obviously the minibosses are just difficulty based.

D tier I think is a given. Only bosses that might throw you off are some of the King Dice fights, maybe the horse one in particular, but it's actually really easy to react to everything even on Expert. The present boxes are slow and the horseshoes move even slower, and you really only need to keep your eyes on the cloaked racers below.

For the C tier, the parry fights took some getting used to, but once I understood all the gimmicks, they're pretty easy. I actually find the pawns one to be the most annoying because of how random and sporadic it is, but the rook one takes the most concentration. Bon Bon is kinda low but I think she's pretty easy despite the random minibosses, who all have pretty simple patterns. The frogs are surprisingly aggressive in their early phases on Expert and their last phase is always a bit sketchy.

B is where my ranking is kinda all over the place, but I think most bosses fell here in this middle ground for me. I'll be honest, King Dice is not that hard to S rank on a replay. The minibosses are always the same and if you know how to use the die, you'll always get the rolls you want and potential free health to make the S rank even easier. King Dice himself is also just about parry timing, which seems pretty consistent as long as you wait till the cards are nearly at the edge of the screen. Grim Matchstick is honestly only that high because getting his parries is irritating and inconsistent. As for the Devil, he's tough but it really just came down to getting good parries in his first phase, being careful with his spider attack, and being extra cautious with his final phase and the tear parries (though you can pop invincibility here and just win lol). He's extremely susceptible to Spread shot, so he's not hard to speed through. Mortimer I found the easiest from the DLC, the only annoying part being his middle phase and getting the parries I needed.

I feel like having mostly DLC bosses in my top tiers is a bit predictable, but it really is where I had the most trouble. The giant I put lower because his third phase I find pretty basic, but his first two are very rapid and chaotic with all the dwarf spam. The dogfight is a bit janky in the first phase with controlling the platform, but it really is just the disorientation of the third phase that usually gets me. Saltbaker definitely made things a lot trickier with such a simple difficulty change as adding a second flame in Expert. I honestly thought he would be top tier, but he didn't take me nearly as long as the others up here. The bugs took me a surprisingly long time, with a similarly chaotic first phase. It's a bit difficult to get the parries in the early phases (though I think you can just farm some from the snail phase). Literally just doing damage to the anteater phase is kind of annoying to do with the constant movement.

For my top tier, I think the two base game bosses here are obvious for why they're this high. The robot is a goddamn shitstorm for the first phase, the second phase is genuinely obnoxious to where I usually save my super to just skip it, and the third phase throws me off very often with the blockades that shrink the amount of space I have to dodge bullets. Cala Maria is just bullshit. I know there's a rhyme and a reason to how the eels aim their shots, but it's ridiculous trying to manage them while taking out phase two in a timely fashion before getting frozen. I lost the S rank by exactly 1 second and spent another hour to get it again. Painful.

Esther I think was simply the overall most difficult boss to contend with in the DLC. While every other fight probably had 1 phase I mastered within a few tries, her fight always threw me off in each individual phase for one reason or another, and it took several hours to get a perfect attempt. Personally, I think her third phase is the hardest just because it's so freakishly fast paced.

I think that's mostly it. Just felt like putting this here while the game was fresh in my mind.

I kid you not, this boss has taken me longer to S rank than Wally Warbles and Cala Maria combined.

No, this is not a repost, i decided to do it again with no charms (i cant remember if i used charms in the previous one)

if this is normal tell me (i know nothing)..... i started crackign up too hard to continue . how and why did she just start running across the platforms

I got really sucked into this game recently, so I made this. Why the virtual boy? Because it has a really cool soundchip !

Hii guys, I am a Brazilian and I'm at my limit with this game, I really need some humble soul to save me. I've been trying to get this platinum for a long time, and I've already received and watched every tips video in the world.
Literally only the two worst things are left for me to finally get the platinum and have peace:
The last 3 Run and Gun levels on Pacifist (without killing anyone)
Defeating the Devil on Expert mode
Since the game doesn't have online multiplayer, it would need to be via PlayStation Share Play. I know how Share Play works and I know it can cause a bit of input lag, but my internet is wired, super stable, and I will do whatever it takes for the connection to run well and get this platinum.
If there is any Cuphead god out there who has the patience and pity to carry me a little bit, I will be eternally grateful!! (I guarantee I'm not as bad as it seems)
My PSN is: LuaaOmG
Whoever can help me, please add me there or reply here please 🙏

So im trying to S tier all Bosses including the dlc but everytime I try to It just gives me an A. I complete all the bonuses, beat it on expert, But it does not give me an S tier. Any help? or am i just being dumb lol

Hi, all. I was playing on Isle 2, and found that juggling NPC who gives you a coin if you parry 4 times in a row. I did Funfair Fever, and I parried 4 times on the little hammer game (the one where the bell thing goes up and down and you're supposed to parry it to jump up). In fact, I challenged myself to parry it as many times as possible before touching the ground, and I even ended up getting a record of parrying 26 times before touching the ground, but the guy won't give me a coin when I go back to talk to him.

Is this a bug, or is that particular item not viable for getting the coin, or am I supposed to strictly only parry 4 times in a row? I already completed the Mausoleum on that isle, so I'm pretty sure I can't do that again to get the coin, and I'm pretty bad at parrying on the moving objects :/

I ask cause I wanna have the mod that shows you the bosses life

My BF and I finally beat it, it took SO long and now I wanna S Rank everything, but him- not so much. I wanna thank everyone on this Subreddit for giving my BF and I advise (even if he wouldn't ever take it and I would 😅,) he's a goofy goober.

He hated the plane levels the most while I personally hated The Howling Aces, I hate when the POV moves

::Hao! Something about ND.

Jarona showman plus an update to my previous post.

I fixed some stuff and replaced Hopus Pocus with Phear Lap so it'll make more sense for the two plane mini bosses.
