The Beast is a Boss encountered in Home after defeating Dogma, and the final boss of Ending 22 and The Binding of Isaac as a whole. It is a gargantuan demonic creature heavily based on the first Beast described in the Book of Revelation .
Introduction cutscene[edit | edit source]
Isaac is laying on the ground of the black-and-white room where Dogma has just been fought. He opens his eyes and looks in front of him. From a pool of TV static (similar to the creep Dogma produces in its first phase) a giant cross rises, towering over Isaac, and falls on him as the screen cuts to black.
Isaac is then shown again, with static pouring out of his eyes and spilling on the ground as if it was his tears. The room's walls are seen collapsing, revealing the outside to be a hellish cavern filled with oceans of lava. The static tears begin to gather and flow back into Isaac's eyes, as if time was flowing in reverse. Angelic wings then grow out of Isaac's back as he twitches in place, and sudden TV-like flickers briefly depict him as ???, The Forgotten and The Lost before he disappears from the floor in another flicker. Isaac then flies up and stares at the hellscape in front of him, but the ground beneath him begins to shake, making him look to his side. Further away, The Beast is rising from the lava, moments before the battle begins.
Behavior[edit | edit source]
At the start of the fight, the Beast will be inactive and will watch from the background. Flying around the Beast are four Ultra Harbingers which will attack Isaac one at a time in the order of Famine, Pestilence, War and Death. Once they've all been defeated, the Beast will let out a roar, submerge into the lava, then reemerge on the right side of the screen.
During its first phase, the Beast will use the same sequence of attacks indefinitely.
- The Beast charges towards Isaac, moving the screen backwards while harmful and destructible stalagmites and stalactites generate behind Isaac.
- At the end of the charge, the Beast begins to inhale large rings of fire which have one small gap that Isaac can fit through.
- After inhaling 8 rings of fire, the Beast stops and fires a colossal brimstone-like beam that covers the bottom and middle portions of the screen.
The Beast enters its second phase at approximately 50% health and loses its inhaling attack, but gains two new ones. Additionally, during the charging portion, some stalactites will be cracked and fall when Isaac passes underneath. At the end of a charge, the Beast will use one of two attacks:
- Opening its mouth and firing three radial half bursts of slower-moving fire, then firing six radial half bursts of fast-moving projectiles.
- Roaring and spawning 4 Souls of the Beast which target Isaac and charge at him before dissipating.
After using either of these attacks, the Beast will submerge into the lake and continually fire large projectiles upwards from the lava in random locations. Afterwards, the Beast reemerges on the other side of the screen, releasing an arc burst of large projectiles in front of it.
The Beast enters its third phase at approximately 33% health. The Beast is forced to submerge into the lava and reappear on the other side of the screen, then charging towards Isaac indefinitely while more stalagmites and stalactites spawn behind him. Cracked stalactites do not appear during this phase.
Once the Beast's health reaches approximately 2000, its horns and body will crack and it will begin to struggle - once reaching roughly 500 health, it'll crack even more, and then, once it is defeated, a large light ray will come from above and strike it down causing Ending 22 to appear.
Damage Scaling[edit | edit source]
Damage scaling is an unclear mechanic introduced by Nicalis in The Binding of Isaac: Afterbirth to provide a more challenging experience to the players, enabling some enemies to retaliate against high damage attacks by deploying an "armor" of a sort to greatly reduce the amount of damage taken. Further details and an in-depth explanation may be found here.
Notes[edit | edit source]
- Chaos Card doesn't work on the Beast.
- Era Walk (Card Link Needed) works for the duration of the fight, and makes for an easy battle.
- Plan C works and will kill The Beast before dying, triggering Ending 22.
- Teleport cannot be used to escape the fight, instead, Isaac will be teleported to a random spot on the screen. This holds true for other methods of teleportation as well such as Cursed Eye
- Ipecac and Haemolacria travel in an arc, similar to Ultra Pestilence's shots, and are extremely hard to aim. Not recommended for this fight. If Isaac has high range when firing left or right, the projectiles go up and off-screen.
- Various familiars such as Cube of Meat or Leech are almost completely useless against the Ultra Harbingers, as the familiars stay stuck in the lava on the bottom of the arena. However, they are able to damage War if his pattern takes him close enough to the bottom of the screen, and the Beast as it is half-submerged in lava.
- Any item that gives an effect for the room such as Box of Friends or The Book of Belial will work for the entire fight, starting with Ultra Famine.
- Broken Watch can affect this fight.
- Gnawed Leaf works as normal in this fight - as long as Isaac stays still and has a familiar, he will eventually kill The Beast with enough patience.
- Homing Trisagion will stay on screen indefinitely during this fight.
- Flat Stone makes tears travel straight down as there is no ground they can skip on.
- Like Flat Stone, bombs fired with Dr. Fetus will be fired in a downward arch since there's no ground for them to slide on, making it a difficult item to use in the fight without bomb negating items such as Pyromaniac or Host Hat.
- Defeating each Ultra Harbinger will grant Isaac's active item 2 charges, similar to Boss Rush.
- All items that grant extra lives will revive Isaac on the spot rather than returning him to the previous room.
- The soul is capable of dragging The Forgotten with him as he moves. This means The Soul can move anywhere on the screen, but at a much slower rate.
- Isaac is granted Dogma at the start of the fight, granting flight, a Holy Mantle shield, an increase in speed & damage, and healing him up to 6 hearts with red and soul hearts.
- Keep in mind that you can still take damage from the stalagmites and the lava below you after the death animation has started, this could be detrimental to your run if you're low on health or if you're playing as The Lost or Tainted Lost.
- Despite not being able to fly or go over gaps in its final form, Bumbo will be able to "fly" around the arena and deal damage without sinking in the lava. Bombs placed by bumbo will behave normally and fall down, however.
- Tears that go up, and off screen, for example with Lachryphagy explosion can use "gravity" in this fight to fall back down at enemy. It's unknown is this bug or a feature.
Unlockable Achievements[edit | edit source]
Trivia[edit | edit source]
- The Beast is the only boss aside from the second and third phases of Rotgut to take place in a Crawlspace-like side-scrolling environment.
- At the end of the fight, Isaac's father refers to The Beast as The Mother of Harlots.
- The Beast wears a tattered version of Mom's dress, suggesting that it represents what Isaac truly sees his mother as.
- When using the "I'm Drowsy" pill during the battle with ultra harbingers, there is one extra slow sign in the position of where the Beast will be, indicating that the Beast is actually "hidden" below the lava before the four ultra harbingers are defeated.
- The Beast's theme is called "Revelations 13:1", referencing the section in the Book of Revelation describing the first Beast.
- A voice performed by Matthias Bossi reads parts of this passage during the cutscene prior to The Beast's fight.
- Revelations 13:1 is the longest track in the entire Rebirth OST, sitting at 7 minutes and 53 seconds. This makes sense, as the theme is highly dynamic, changing depending on where the player is in the fight.
- During the part of the theme that plays during the fights against The Beast proper, Latin chanting can be heard in the background sometimes. The chanting is "mori bestia, cum nostra lucis", which translates to "die, Beast, to our light".
- Revelations also says that the Lord is who defeats the Beast, which may be who is responsible for the beam of light at the end.
- In the cutscene prior to the Beast's fight, Isaac transforms into ???, the Forgotten and the Lost, referencing the events of Ending 20.
- Having enemies be turned into poop with E. Coli or by using other means to do so affects the game's parallax scrolling, as the poop will remain on the screen regardless of whether or not the screen is scrolling.
- In the fight's background, each of the four Harbingers can be seen doing a small animation before they fly into the foreground. Ultra Famine chuckles, Ultra Pestilence raises his fists in the air, Ultra War becomes enraged, and Ultra Death facepalms before brandishing his scythe.
- They can also be seen doing a small animation whenever Isaac takes a hit. Ultra Pestilence waves his arms and grins, Ultra War raises his arms and then "slams" them down, and Ultra Death laughs.
- According to the game files, the Beast's boss fight takes place in Hell itself.
- Despite being in a standard fire-and-brimstone depiction of Hell, Isaac's last will still retains Home's "some cold place" location line, rather than changing to something more accurate.
- The Beast is the only boss in the game to have a cutscene before its fight instead of a Versus screen.
Bugs[edit | edit source]
|Bug!||Using Delirious during the battle will cause the background to become entirely black. The game attempts to change the background of the Beast fight to a normal floor background, which cannot be displayed properly due to all other backgrounds lacking many unique properties that only the Beast's special background has.|
|Bug!||If the player has Knockout Drops, a sufficiently high amount of luck and an item that fires multiple tears at once (such as Monstro's Lung), they will be capable of knocking the Ultra Harbingers far off the screen during The Beast's fight. This also occurs if the player has Strange Attractor and enough sources of tears being fired.|
|Bug!||Blood Rights can still damage The Beast even when she is in the background, and can erroneously initiate her third phase before all of the Ultra Harbingers are defeated. The Beast remains intangible during this phase, but can still deal contact damage to Isaac.|
