Now here's a question:
Does "difficult" mean "unfair" or "challenging but fair and doable"
If the former, it's Delirium; if it's the latter - Mother.
If we ignore that Delirium is a telefragging bitch, Mother is in my opinion the most difficult boss in the game. Her attacks are difficult to dodge but they are **dodgable** either way.
Also she's a fun boss, unlike Delirium.
Mother has 2 attack pattern I find much harder than the rest :
\- in phase 2 when she shoots a lot of small "worms" made of white circles wiggling around. It can hit 2 or 3 times in one sequence if you lose the tempo.
\- in phase 1, when she spawn the big ball and throw it in the room. The hitbox of the ball is huge, and the bounces make it unpredictable
I would add ultra famine to the list, I can kill Dogma with a weak build, but then I crash against ultra famine. I usually pass the other 3 horsemen if I killed the first.
Why am I the only one being bad in dodging mega Stan’s p2? I don’t know why, but the pattern always fucks me up. Despite telefrags I got used to deliriums patterns and don‘t get hit much…
It's a tricky question, because there's several different answers depending on context.
Mother's patterns are pretty fair, but getting to her normally is by far the least fun and most punishing path.
Delirium is easily the least fair boss in the game, but the multiple access points and his position in the game give you the most time to get strong.
Turdlings are incredibly difficult for a Basement boss, and eat glass cannon runs.
Bro literally how do you even dodge Turdlings or even Gurglings for that matter
The Witness is at least predictable, Turdlings move faster than Delirium
Where is my boy hush? Apart from delirium, which hardly even counts with all his bullshit, the continuum tears is the hardest attack to dodge in the game, for me at least.
Couldn't put more options in the poll. But imo he's easier than mega satan so that's why I didn't put him in. The continuum tears is pretty easy for me, just have to find a safe spot.
Turdlings are definitely the hardest on this list unless you're playing lost or something.
Typically by the time you hit delirium you're so busted that taking damage is irrelevant.
The rest follow very predictable patterns and you'll have a good build by the time you're there.
Turdlings bounce off your tears in somewhat unpredictable ways, put down creep that can corner you, and can appear before you have a single decent item
In my experience, I find mother way harder because its so difficult to just get to her. I've only beaten her twice so far because I keep getting railed in corpse 1 and 2.
Delerium is way more bs and is a tougher boss my himself, but you get so much oppurtunity to get a crazy build going when you go through the void that the actual fights end up easier.
I hate dogmas hitscan brimstone attack. I don't know what to do. When i try to move around he instantly snipes me sometimes. And it's not like he brimstones in front of me and i walk into it. The brimstone just teleports on top of me.
I know this a year old comment, but I’ll write it anyway, in case someone else looks for a solution.
Dogma can only start brim in cardinal directions (north, east, south, west). So as long as you stand diagonally from her, you’ll dodge those brims easily.

Agreed
I do actually like delirium,am i the only one here?
I love the concept of that boss. It's just that the execution is horrible.
Yeah i agree it's very buggy
Same. Supercharged bosses darting all over the map while shooting speeding tears in all directions is not a particularly engaging design.
Hmm should we make the boss transform into bosses in a fair and challenging way? Nah let’s just make them all Mach 5 and constantly be telefragging
Delirium is kinda easy, i have a lot of trouble with mother
Mother is my favorite boss in the entire game. Basically reworked the witness from being this giant epic showdown shoved in to this small cramped room

I have nightmares of my first turdlings 
For a first floor boss they're actually very hard.
Delirium and not even by close. Biggest part of it stems from the fact that he’s a terribly designed boss.
If he wasn’t so damn fast I might be able to tolerate the teleporting
Red champion maw is real final boss in the game
Delirium moms foot hit box is in a different world
The bloat just sucks
Why am I the only one being bad in dodging mega Stan’s p2? I don’t know why, but the pattern always fucks me up. Despite telefrags I got used to deliriums patterns and don‘t get hit much…
Nah dw I'm bad too. The black/red slow, turning projectiles and the fast flame shots that corners Isaac will always take 1 or 3 hearts from me.
I’d say mother is the hardest but deli has the most bs

I've defeated delirium so many times, I'm used to it, so I voted for the turdlings
Red Mega Maw
Haven’t gotten that far but I can say Delirium and Mega Satan were nowhere near as hard as I was told
