The Binding of Isaac: Rebirth

Hardest Boss as of Repentance?
I just want people's opinions on what they think the hardest boss is between Ultra Greedier, Hush, Delirium, Mother, and the true final boss (which I actually find the easiest/second easiest out of the five). For me, the hardest boss is Mother.

Scourge is very hard too, without good equip its hard to not lose health
Scourge and Mother sometimes do some serious damage even if you know how to deal with them...

Also that variation of Infamy in the alt floor is super strong as well

Still Delirium. Unlike every other final boss, Delirium is still completely unpredictable, and as far as near-unavoidable damage goes, Delirium's instant stomp is still the undisputed king of jank.

I dread fighting Hush on runs where I really can't afford to take damage. Most end bosses are manageable enough (even Mother, outside of the ball attack that I still don't know how to dodge well though usually I have phase 1 done fast enough to not even see it) but Hush's continuum volleys can overlap in some seriously nasty ways, and I swear that the light beams are faster than I am sometimes.

Honorable mention to Delirium. Sometimes a surprisingly fair fight, sometimes will telefrag me 4 times in a row. I don't know what to think of it.

Ultra greedier isn't hard just incredibly boring with his boss armor.

Corpse mother is the hardest because you get to her the weakest. Unless you take a very early portal to the void. The beast path you can ez get a free planeterium as well as skip any curse of the blind item rooms going down (And get everything going back up without the curse still being there).

The only positive of the corpse mother path is you can keep the polaroid, which only matters if you get down to pure soul hearts/no red hp remaining.

If I do not have a lot of health, hush and Mother (probably, i have only fought her once and I beat it) are impossible for me lol. I dont find delirium very hard for some reason.

The hardest miniboss is very obviously Krampus. The hardest normal boss is probably The Scourge, his bullet hell attacks surpass most of the final bosses. The hardest (functional) final boss is Mother, as others have said that you can lose health EXTREMELY fast if you're not careful. She's also one of my favorites. The ACTUAL hardest boss is still that moldy blob of ♥♥♥ Delirium and his buggy hyperspeed telefragging attacks.

I've had no issues with Delirium. I honestly don't see what the issues people have with it. As long as you don't stand still and are good, it's not that hard of a fight.

Pin. His explosive shot always gets me >:(

Delirium is strongest - unless you have tons of damage and way to restore hp, he's ubeatable. Because he has no strategy - he moves chaotically filling whole room with bullets.

Mother is second but mostly because you need to suffer whole way going to her.

Dogma is third because it's wheel attack is undodgable, I dunno why they did that.

The rest are strong because they can be uncomfortable for certain builds and can kill you just because of that.

incorrect, even with low speed it's doable

Seriously though, Dogma's "ophanim charge" and Colostomia's everything are both possible to dodge on base speed if you understand how they work. The trouble with the latter is that a) failing to dodge the charge properly won't actually damage you until she throws a bomb, which makes it less obvious what you're doing wrong and b) clouds are a new mechanic, so people used to the pre-Repentance days don't seem to be noticing them.

When I played Red Redemption I've almost beaten Mother, but still died. I was so frustrated I decided play as a character I've already beaten her as, gave myself 5 tears and 10 dmg via boss items and battled her so much she is a walk in the park for me rn, except the spinning attack which gets me when she's too close.
Delirium has to be the hardest just bacuse telefrags, but that's only because he is the only unreadable boss, meaning you never really gitgud with him.
Normal bosses are the sh1t condom, the scourge, the minecart bomber guy. Hate those dudes

Probably still Dellirium. Telefrags and randomness is just painful.

From new bosses: The Pile. That piece of bones is not only tanky, but also have quite unpredictable attacks. Other than this all new bosses feels quite fair.
