History DemonicSpiders / TheBindingOfIsaac

* The MookMaker Portals in ''Afterbirth+'' quickly became infamous. They're quite common, appear in pairs while surrounded by obstacles or other enemies, and summon a varied assortment of enemies at a fearsome rate. A nerf slapped these pretty hard after numerous complaints, making it so the portal has a chance of expiring on its own after each enemy summoned, made more likely with repeat summons.

* Whippers. These creatures have a fleshy tendril that they use to hit back tears and even bombs if they hit one. Only way to really be safe with them is to have a laser of some sort but that won't always be the case/ Not helping is that they are fast to boot as well.

* Bombgaggers. [[ThatOneLevel Only appearing in 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 [[TakingYouDownWithMe spit out the bomb anyways.]] Hope you got something to protect yourself because they also come in groups.

* Revenants. [[GodDamnedBats A more horrifying variation of 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 appear with the [[GodDamnedBats Bishops]] so you can see how well this will go.

* Cursed Globins are pretty much like the other Globins but with a twist: When they become a pile of ooze, the pile multiplies into a second pile which will reform if they get the chance. Cursed Globins quickly become a battle of trying to stop yourself from being overwhelmed by a swarm if or when things go wrong for you.

* Whippers. These creatures have a fleshy tendril that they use to hit back tears and even bombs if they hit one. Not helping is that they are fast to boot as well. They are also found in quite a few floors like Maus and even Sheol.

* 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 [[DemonicSpiders 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)

* Gehenna may not be on the same rage enducing 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 hellspwans 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!

* Gehenna tends to be more fair (or at least less rage educing) than Ashpit.. And then you meet I'd call "Mini Fallens" or officially named Black Goats. Only appearing in Gehenna these hellspwans can charge into you without much warning and have the Fallen's same laser attack. And to make things worse, they appear in groups of four. Fun!

* '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.

* ''Repentance'' also added Polties, and their variants Kinetis, both brought back from the ''Antibirth'' mod. Polties fly around in the room and grab obstacles (rocks, buckets etc.) and throw them at the player. This wouldn't be problematic at all if the trajectory of the thrown obstacle wasn't completely unpredictable. Sometimes, Polties will throw obstacles exactly on your position, but sometimes they will predict how you are going to avoid and correct the trajectory. Kinetis are even worse in that they don't even need to physically grab obstacles, instead they will make them fly towards them (and of course you take damage if you hit the obstacle while it is being moved).

** 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.

* Vis are enemies that shoot [[ThatOneAttack Brimstone]] [[FrickinLaserBeams 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.

* And, well, basically ''everything'' that can cause you to take damage in the Womb and Beyond, since they do one heart per hit instead of half, including spikes and Curse Room doorways (unless you have The Wafer or Cancer; the former reduces any and all damage to half a heart, while the latter only does so in a single room after taking damage).

** Rage Creeps fire Brimstone lasers. Here's the catch, since the last place you will look an enemy for is the walls (which they reside on), it's very likely you'll want to seize control of the center of the room. However, by that moment, Rage Creeps will likely had fired a beam that you'll be caught on (and sometimes get hit twice by it). And even discounting that situation, they remain very dangerous because their attack has short tell and infinite range. ** The Things (Red Creep).

** 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.
** Lvl 2 Spiders and Ticking Spiders aren't left behind either. They can move as quick as a regular spider and jump like a Trite (though much less distance), and have around the health of the latter. Ticking Spiders also explode on death, making taking on them from afar the best thing (and still not guaranteed to work) to do.

* The entire class of spider enemies are this both literally and figuratively. They all have erratic movements over random vectors, making it very likely they will collide into you for damage. Even the smaller spiders aredangerous because of this! The Baby Long Legs and Small Baby Long Legs are subclasses of MookMaker spiders that will actively run away from you while spawning regular spiders (Baby Long Legs) or spider-spawning Sacks (Small Baby Long Legs). Failure to kill these enemies quickly will result in the room filling with spiders, very dangerous in the early game when your damage output and tear firing rate are low.

Nearly everything in the basement that moves (and a lot of things that don't) [[EverythingTryingToKillYou are trying to finish what Isaac's mom started]]. [[DemonicSpiders These guys]] try harder than most.

** Special mention goes to Trites, which debuted in Wrath of the Lamb and subsequently appeared in Rebirth. These jumping spiders are just like Hoppers, except they move at nearly double speed, take more hits, and often come in packs of 4 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.

* Mr. Maws. They fling their head at the player if they come close, which can be very hard to dodge due to its speed, and upon death, they leave shooting Maw heads (and sometimes slow-moving Gusher bodies) behind which can be a problem of their own. Even bombs and Brimstone (unless buffed with extreme damage) won't get the head on the first hit. They can be the utter bane of people going for No-Hit runs, because there's one room configuration that they are practically impossible to dodge as you enter. Variants include:
** Mr. Red Maws, faster variants which, when killed, leave behind a Red Maw head (which, granted, only fires one tear in each cardinal direction when killed)
** Swingers, Maw heads attached to a Globin's liquefied body, which constantly swings its head around its body in a wide arc.

* Knights have a rock-solid front end that shrugs off almost all attacks. Its weak point is the exposed brain on its back, but good luck getting a clear shot at it without any piercing tears, since they have a tendency to turn around and run right into you after you position yourself behind it. To make matters worse, Knights come in several variants with small changes designed to prevent you from getting behind them in as easily:
** Selfless Knights have Isaac's face in place of the brain and have massively increased speed, which allows them to charge across a room to you in under a ''second''.
** Floating Knights are essentially slightly slower, flying Knight heads, which can be a pain to get behind in a room with a lot of obstacles such as pits, spikes or rocks.
** Bone Knights are a Sheol-exclusive variant which leaves behind a thin trail of creep, making it difficult to get behind them without taking damage (barring that you have an item which grants creep immunity, such as Callus or some form of flight). They gain a speed boost, though they're not as fast as Selfless knights.

* Clotties, when in groups or in certain room layouts. They move around haphazardly, fire in all four cardinal directions at once (which forces you to either put yourself in danger to hit them every time or use unreliable diagonal shooting, which may not always be viable in certain layouts), and do so at completely random intervals (i.e. not guaranteeing you'll even have enough time to try to hit them) with next to no warning. Even worse are I.Blobs, Isaac-like varieties that do 8-way shots, making even diagonal shooting dangerous. Fortunately, these are extremely rare, but if you are unlucky enough to see one in a floor, expect to take some damage.

* The new wall-crawling Creep spider variants in ''Rebirth''. They come in three variants, with a fourth introduced in Afterbirth+: Wall Creeps (three-shot burst in a straight line), Blind Creeps (triple shot in a spread-out pattern), Rage Creeps (Brimstone laser) and The Things (Red Creep). Wall Creeps are annoying but easy enough to kill. Blind Creeps appropriately fire without warning, move randomly across a wall and can potentially spawn in as three of them stacked on one side in certain rooms, making it difficult to kill them without taking damage. Rooms with Rage Creeps often have you taking damage from the infinitely-ranged Brimstone laser *immediately* as you enter the room, sometimes twice from the same laser.
* Walking Hosts, mobile variants of the Host enemy which are invincible until they fire upon the Player. These enemies are much harder to coax out of their shell while they slowly walk to you, and often come in rooms where it's tricky to maneuver around. The 2x2 room containing four of these enemies and the perma-firing Grimaces is one of the most notorious rooms in the Caves.

* You know those invincible Death's Heads that bounce around the room until you kill all the other enemies in it? ''Afterbirth+'' adds Stoneys, Fatty variants resembling Grimaces which do an impressive job at being a hindrance. It comes in pairs or large groups and follows you around quickly, providing cover for the rest of the enemies. If those guys spawn at Greed mode, they'll more often than not last until the final wave of enemies and leave you next to no room for avoiding threats. The only saving grace is that they don't damage you on contact. It didn't take long for a {{nerf}} to hit them, making it so they have to catch their breath after chasing you for five seconds.
** Booster Pack 5 adds in 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.

** Swingers, Maw heads attached to a Globins liquefied body, which constantly swings its head around its body.

* The entire class of spider enemies both literally and figuratively. They all have erratic movements over random vectors, making it very likely they will collide into you for damage. A subclass of MookMaker spiders will actively run away from you while spawning regular spiders or spider-spawning egg sacs. Failure to kill these enemies quickly will result in the room filling with spiders, very dangerous in the early game when your damage output and tear firing rate are low.

* Mr. Maws. They swing their head at the player, which can be very hard to dodge, and upon death, they leave shooting heads (and sometimes slow-moving bodies) behind which can be a problem of their own. Even bombs and Brimstone (unless buffed with extreme damage) won't get the head on the first hit. They can be the utter bane of people going for No-Hit runs, because there's one room configuration that they are practically impossible to dodge as you enter.
* Psychic Maws. They're a variant of Maws, which are already annoying enemies. These fire homing tears, have increased health, and have an Eternal Fly circling around them which can block hits. Fortunately, they are rather rare.
* Knights have a rock-solid front end that shrugs off almost all attacks. Its weak point is the exposed brain on its back, but good luck getting a clear shot at it, since they have a tendency to turn around and run right into you after you position yourself behind it. To make matters worse, there's a version of this enemy with Isaac's face in place of the brain which ''charges at you at full speed.''
* Eyes, especially when they're not located in the center. These are likely to hit the player. The bloodstream versions are even more dangerous (especially without having a weapon to shoot over rocks), as bloodstreams last longer than EyeBeams and they're often situated between rocks, making it hard to hit them.
* Clotties, when in groups or in certain room layouts. They move around haphazardly, fire in all four cardinal directions at once (which forces you to either put yourself in danger to hit them every time or use unreliable diagonal shooting, which may not always be viable in certain layouts), and do so at completely random intervals (i.e. not guaranteeing you'll even have enough time to try to hit them) with next to no warning. Even worse are I.Blobs, the white "Alternate" varieties that do 8-way shots, making even diagonal shooting dangerous. Fortunately, these are extremely rare, but if you are unlucky enough to see one in a floor, expect to take some damage.
* Chubbers. They have the same appearance as a Vis (the walking stomachs that shoot giant lasers at you) but have a small Chub housed inside each of their bodies, which fires rapidly, can go through rocks and walls, and takes out a whole heart of health. It doesn't help that they have an insane amount of HP and often come in packs of 5 or 6. Made even worse in ''Rebirth'': their Chub now blocks tears!

* Hangers, which are basically hostile shopkeepers. They fire three way shots, have Eternal Flies circling them, and have a ''ton'' of health.
* Masks and Hearts. The mask is invincible, and is connected to a heart which can soak a lot of damage. The masks charge and have very good reflexes. The hearts try to flee from Isaac, and if he gets too close, fire four shots in the cardinal directions (like the Clotties) to defend themselves. Fighting them in rooms with rocks makes them even harder to deal with. Finally, they are rarely alone. Good luck dodging the extremely nimble masks while trying to get a clear shot at the hearts, which retaliate on their own accord.
* And, well, basically ''every enemy'' in the Womb and Beyond, since they do one heart per hit instead of half.
* The new wall-crawling spiders in ''Rebirth''. They come in three flavours: three-shot burst, triple shot, and Brimstone. The three-shot burst version is annoying but easy enough to kill. The triple shot one is blind, fires without warning, and moves random. Rooms can potentially have three of them stacked on one side, making it difficult to kill them without taking damage. Rooms with the Brimstone variety often have you taking damage immediately as you enter the room, sometimes twice from the same Brimstone laser.
* The Walking Hosts. These enemies are much harder to coax out of their shell while they slowly walk to you, and often come in rooms where it's tricky to maneuver around. The 2x2 room containing four of these enemies and the perma-firing Grimaces is one of the most notorious rooms in the Caves.

* Also in Greed Mode, Death's Heads, the invulnerable enemies that bounce around the room and only die if the room is cleared. The problem in Greed Mode is that if you can't kill the wave fast enough (quite likely given that they tend to spawn alongside tough-to-kill enemies like Walking Hosts), you'll end up having to deal with ''more'' enemies spawning on top of you, which means more things you have to kill to get rid of the Death's Heads. And the next wave that spawns could very well include ''even more'' Death's Heads, at which point you will not have very much room to dodge and hitting something that actually takes damage becomes nigh-impossible.
* ''Afterbirth'' added a skeletal version of Mom's hand which is approximately 100 times worse than the original. The original just flew down and tried to grab you. This one does the same, only when it lands, it releases an earth wave like The Cage, and when it dies it releases spiders.
* ''Afterbirth'' also gives us the Imp, which is basically what you get if you take a Baby, 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 hang out in Devil Rooms, hiding behind the statue to get cheap shots on you before you fully register that it's there.
* ''Afterbirth+'' has the occasional [[ChestMonster mimic chest]]. There used to be no way to know in advance if they're spiked chests in disguise until you stand right next to them. Being forced to carefully check each chest when previously you'd just run into them was perceived as a unwarranted annoyance by most players. The design was thankfully changed to feature blood splatter and darker gray color, making it fairly easy to tell at a glance.
* The MookMaker portals in ''Afterbirth+'' quickly became infamous. They're quite common, appear in pairs while surrounded by obstacles, and summon a varied assortment of enemies at a fearsome rate. A nerf slapped these pretty hard after numerous complaints, making it so the portal has a chance of expiring on its own after each summon, made more likely with repeat summons.
* You know those invincible head enemies that bounce around the room until you kill all the other enemies in it? ''Afterbirth+'' adds a Fatty variant of it that does an impressive job at being a hindrance. It comes in pairs and follows you around quickly, providing cover for the rest of the enemies. If those guys spawn at Greed mode, they'll more often than not last until the final wave of enemies and leave you next to no room for avoiding threats.
