History DemonicSpiders / TheBindingOfIsaac

** Special mention goes to Trites. These jumping spiders are just like Hoppers, except they move at nearly double speed, take more hits, and often come in packs of four or more. Most importantly, they can jump about twice as far as Hoppers, and occasionally decide to jump a tile or two ''behind the player'', which makes them impossible to dodge no matter what you do. The expansions even gave them a couple of variants: Raglings spit two orbiting shots around themselves in addition to jumping and are tougher, but fortunately aren't as aggressive. Blisters spit the same homing Dark Balls spawned by Little Horn, giving you a lot more stuff to dodge; to top it off, they used to have an absolutely ''ridiculous'' amount of health and could replace Ticking Spiders in the ''Basement'', though thankfully a patch nerfed their health to only moderately above average.

** Mr. Mines, stationary Flooded Caves-exclusive variants which launch themselves at nearby players, can burrow underground to pop up in another pit and release six shots in all directions upon death.

* I. Blobs, Isaac-like varieties of Clotties that behave in a combination of them and Clots: they fire 8-way blood shots, which makes even diagonal shooting dangerous depending on your items. Fortunately, they are extremely rare, but if you are unlucky enough to see one in a floor, expect to take some damage.

* Hangers, which are basically hostile shopkeepers. They fire three-way shots, have Eternal Flies circling them, and have a ''ton'' of health. Oh, and taking damage from them also makes you drop coins.
* Masks + Hearts, which are essentially Knights with the brain separated from the body. The Mask is invincible and can only be destroyed by attacking its accompanying heart, which can soak a lot of damage. The masks charge and have very good reflexes, much like a knight, while hearts try to flee from the player, and fire four shots in the cardinal directions (like the Clotties) to defend themselves if they get too close. Fighting them in rooms with rocks makes them even harder to deal with, and they're rarely alone, often spawning in groups of three or more. Good luck dodging the extremely nimble masks while trying to get a clear shot at the hearts, which retaliate on their own accord.

* Leeches, leeches, ''leeches''. First of all, these little buggers are ''fast'', at least when they notice you. Second, more often than not, they appear [[ZergRush in large numbers]]. Third, they're affected by knockback a ''lot'' more than other enemies. While this sounds like good news on paper in that you'll be able to knock them away, more often than not they'll just get knocked into the direction you're currently moving in, making for incredibly hard-to-avoid damage thanks to the aforementioned speed they possess. Oh, and guess what? Leeches can be replaced by two ''[[FromBadToWorse even worse]]'' variants - Kamikaze Leeches, which [[ActionBomb explode on death]], and [[LightIsNotGood Holy Leeches]], which not only sport the death explosion attribute that Kamikaze Leeches do, but they have an Eternal Fly circling around them, which can easily block your shots, and it makes their hitboxes bigger, making it more likely that you'll take damage! '''''[[{{Angrish}} AAAAAAARGH!]]'''''

* ''Afterbirth'' also gives us the Imp, which is basically what you get if you take a Baby, put it in Sheol/Devil Rooms, give it more health, make it actively try to dodge your shots, and make it shoot five times in a row. To top it off, these guys love to hide behind Satan's Statue in Devil Rooms to score cheap shots on you before you fully register the Imp's presence.

** Booster Pack 5 adds in the Cross Stoney, which are essentially Stoneys with a Cross Grimace for a head, which periodically fires four shots cardinally and diagonally. Thankfully, these are only encountered in the Aprils Fool challenge.

* Psy Tumors, who begin to appear in Cathedral. You know those enemies that look like a cloud with a butthole who spit projectiles in all directions, like, non-stop? These ones shoot ''homing shots''. Your tactic to fight these guys is either pray you have cover of some sort, or hope you can kill them before they drain all your health. If you encounter a room full of them, you're basically SOL.

* [[WhipItGood Whippers.]] These creatures have a fleshy tendril that they use as a whip to hit back tears and even bombs if they hit one. The only way to be really safe when pitted against them is to have a long-reaching weapon (like Technology or Brimstone), but that won't always be the case. They also tend to corner you with the help of other enemies in the room, and are fast to boot.

* Leapers, the bane of any player going for a NoDamageRun [[spoiler:(or playing The Lost)]]. Their erratic jumping makes them hard to hit consistently, they can jump to any part of the screen with little warning, and when there's four of them, the screen tends to be filled with bullet spam from repeated jumps. A real pain to deal with.

* Any of the Ascent only monsters can count for their high health.. And the one that has caused the most strife is the Tainted Spitty. High health? Check. Annoying bullet that they fire all the time? Check! Appears with other monsters like [[GoddamnedBats Chargers]]? Check! Never stops firing bullets? CHECK! Pray to Dogma (or the RNG) that these things don't end the Alt Lost run. (If any of the others here don't, that is.)

* Revenants. A more horrifying variation of [[GoddamnedBats their skeleton selves]]. They don't fire bones but instead spew out fire. They also follow you while they are doing this and come in groups so there is not much place to run when they start. The fire can also go over gaps so flying won't help you here. They also can appear with the Bishops, so you can imagine how well this will go.
* Bombgaggers. Only appearing in [[ThatOneLevel Ashpit]], of course. These things spit out a giant bomb that yes causes the biggest explosion in the game with lots of range to it. And even when you kill them, they [[TakingYouWithMe spit out the bomb anyways]]. Hope you got something to protect yourself because they also come in groups.
* Gutted Fatty. These things use their guts to attack you by ejecting them out of themselves. Their guts spawn Chargers, they are VERY tanky, and the worst part is that as you attack, their eyes (which won't die till they do) pop out and follow you around. And when they die, any guts will still live and keep spawning Chargers.

* I.Blobs, Isaac-like varieties of Clotties that behave in a combination of them and Clots: they fire 8-way blood shots, which makes even diagonal shooting dangerous depending on your items. Fortunately, they are extremely rare, but if you are unlucky enough to see one in a floor, expect to take some damage.

* ''Repentance'' introduced Needles, and their variants Patsy, informally known as "Mini-Pins": enemies that burrow underground and periodically emerge to lunge at the player, similar to Pin. The enemies themselves wouldn't be that bad, except for one major detail; ''nothing'' indicates they exist in the room until they're leaping out of the ground to attack, which generally takes 1 to 4 seconds. This is fine when they're the only enemies in the room, as the doors locking in a room that supposedly has nothing in it is an obvious clue. However, they can also be in rooms with ''other'' enemies, resulting in situations where you're in the middle of fighting them off and suddenly get beaned in the face by a Needle [[FakeDifficulty you weren't aware of until right when it attacked]]. It's incredibly common to run straight into a Needle by accident because you were dodging under the belief that the enemies you can see were the only ones in the room. And to make matters worse, they're '''everywhere''', appearing in 10 different maps and in a whole bunch of rooms. It goes to show you, [[TheThreeCertaintiesInLife three things are inevitable in life: death, taxes, and Needles]].
** Patsy are even ''worse'' because they also shoot tears in the diagonal directions when they emerge from the ground, and are obviously found in [[ThatOneLevel Ashpit]]. But at least they only show up there and Flooded Caves. But believe it or not, it's actually possible for one to show up in a Secret Room.

* Gehenna may not be on the same rage inducing level as Ashpit but there are still monsters that can break your day. Meet what I'd call "Mini Fallens" or officially named Black Goats. These hellspawns can charge into you without much warning and have the Fallen's same laser attack. They also fly so rocks or the Lost won't help. And to make things worse, they tend to appear in groups of four. Fun!

This is all well and good, except for a small minor detail: you don't know they are in the room until they emerge. Sure, if you enter an empty room and the doors lock behind you, you can infer they are here, [[ParanoiaFuel waiting]]. What makes these enemies incredibly annoying, and sometimes almost [[FakeDifficulty unfair]] is the fact that they can also be in rooms with ''other'' enemies. As such, you are dodging attacks by running around when suddenly a Needle emerges from the ground right in the direction you are moving, but you cannot do anything to avoid it because you did not assume there were other enemies in the room. It is incredibly common to run straight into a Needle by accident because nothing else was possible.

* Vis are enemies that shoot [[ThatOneAttack Brimstone]] [[EnergyWeapon beams]] on your direction when they see you. Scarred Vis shoot them on your direction and behind them. But none of them take it to a level as grueling as '''Scarred Double Vis''' do. On mere sight of you, they shoot on all four cardinal directions. This leaves very little room to dodge. Keep your witz when you see these specific variants pop up suddenly in The Womb.

* 'Repentance'' has a mulligan variant taking this role. Yes really. Holy Mulligans. Only in the Cathedral these "holy" monsters only summon one thing and that thing happens to the angelic baby which is another difficult monster to deal with. Combine that with the fact that you will likely be dealing with another unholy creature (those leeches.) and the fact that they seem to spawn as many as they want you are in for a ride.
