"Then, in the middle of all the chaotic cries, someone shouted: “It's the beast! A big, scary monster lives in the black, dusky forest!” "
- Tale of the Black Forest
Apocalypse Bird is a monstrous Abnormality, which only appears when Punishing Bird, Bird of Judgement and Big Bird are merged together after going through the 'Entrance to the Black Forest'. The monster possesses a bandage-covered body, with the revealed head of Bird of Judgement at the top of it, and the mouth of Punishing Bird in front the body. It has big talons covered in bandages, as well coming from the top of the body, and big black wings with the several yellow eyes of Big Bird on it, coming from the back.
Unlike other breaching Abnormalities, this one can't be suppressed by usual means, because it is immune to all damage. It can only be defeated by destroying the 'eggs' around the facility. Its encyclopedia can be accessed from the encyclopedia menus of the other birds during the event, after they merged.
Ability
Its ability will trigger when Punishing Bird, Bird of Judgement and Big Bird are breaching at the same time. If 2 of the mentioned Abnormalities are breaching, the other will breach immediately and trigger the event. The event can only trigger on Day 21 and onwards.
When the condition is met, the event will start with a picture, beginning to tell the tale of The Black Forest. After that, a black portal gate, named the 'Entrance to the Black Forest' will appear in a random main room of a department. All the three birds will start to go towards the portal, ignoring their usual behavior. They will become immune to damage, and they cannot be targeted. However, the portal can be suppressed, which will end the event prematurely and return the Abnormalities to their containment units, but due to its high 
HP at 13,000 and the fact that it's highly Resistant against 
all damage types (x0.3), this usually isn't accomplished.
When one of the birds reach the portal, a picture will appear, depending on which one of them reached the portal at the time, telling a part of their initial role in the story. The portal will change after each scene. When all the birds entered to the portal, another picture will appear, showing the 'monster' and after that, with a roar, Apocalypse Bird will be summoned.
The whole facility's lights will shut down and Apocalypse Bird will periodically induce Qliphoth Meltdowns in the containment units of random Abnormalities across the facility (Sephirah Meltdown immunity doesn't affect these Meltdowns). From this point, the player cannot change the flow of time, pause, or enter the pause menu.
Apocalypse Bird can only teleport to the main department rooms and it possesses a variety of powerful attacks, listed here:
- It can deal strong (23~44)
Black Damage to the employees and Abnormalities in front itself with its talons, shaking the screen when hitting the floor. - It can charge a yellow orb, possessing random employees in your facility and drawing them towards itself. Possessed employees will be freed from the Possession when reaching the Abnormality. (Big Bird)
- It can open its wings and fire several yellow beams from its eyes at nearby employees, each beam dealing (8-15) Black Damage. (Big Bird)
- It can use a golden balance, dealing (10~16) Pale Damage to all the employees in the facility. (Bird of Judgement)
- It can open the big red mouth in front its body, dealing massive (50~116) Red Damage to the entities in front it (Punishing Bird)
The Abnormality can't be damaged due to being immune to every Damage Type. Even if Apocalypse Bird itself were to somehow take damage, it has an absurdly high amount of HP at 330,000. The only way to defeat it is by destroying the 3 'eggs' scattered around the facility, taking out 1/3 of their HP; which will spawn in random main department rooms when Apocalypse Bird is summoned. All eggs are weaker to certain Damage Type and their appearances will change when their HP is dropped below 50%. Destroying one of the eggs will make appear a picture of the respective bird being defeated and removing part of the abilities of Apocalypse Bird, making it weaker.
The 3 eggs, along with their appearance and effects, are:
- Small Beak: A white egg similar to Punishing Bird's body, with a big red mouth at the front. It possesses very high HP at 6400. Destroying it will prevent the monster from using Punishing Bird's ability.
- Long Arms: An egg covered in bandages, similar to Bird of Judgement's head. It possesses very high HP at 9900. Destroying it will allow you to access the game speed and pause functions, and also prevent the monster from using Bird of Judgement's ability.
- Big Eyes: A black egg covered in Big Bird's yellow eyes. It possesses very high HP at 6400. Destroying it will turn the lights of the facility back on, limiting the monster's use of Big Bird's abilities.
When all the eggs are destroyed, the last scene of the tale will appear, and after that, Apocalypse Bird will fall, defeated. All the birds will return to their containment rooms. The same event can't occur twice in the same day.
All the Agents who survived the event will receive a Special E.G.O. Gift, called 'Through the Dark Twilight', giving them a black wing with eyes at the back of the Agent (Slot Back Right), the same as Apocalypse Bird, and increase all 
stats by 7. Additionally, the player will get Apocalypse Bird's E.G.O. Equipment (Weapon and Suit) after defeating the boss. The E.G.O. Weapon and Suit can be saved by returning to the Memory Repository or passing the day, but the E.G.O. Gift can only be kept upon passing the day.
If an Agent in the facility is wearing the E.G.O. Weapon and/or Suit of Apocalypse Bird, the event will not occur even if all three birds breach.
Origin
Apocalypse Bird is the result of Big Bird, Bird of Judgement and Punishing Bird fusing together into one bird in an attempt to protect the Black Forest from monsters, since they felt that the forest was too big for just the three of them to protect, but that nobody else can protect it like them. When Apocalypse Bird appeared, darkness and chaos fell upon the forest, chasing away the forest's residents.
Apocalypse Bird ended up all alone in the Black Forest it tried to protect, with neither the sun or moon shining upon it. The prophecy had been completed.
The tale of the Black Forest can be found in its Encyclopedia Entries.

Story
Apocalypse Bird's encyclopedia portrait
- "Known to come when the world is filled with sin, many employees fear the advent of this Abnormality. To talk about this bird, we first need to tell the story of the Black Forest. We must remember the forest that was once so peaceful and beautiful… And the apocalypse shall follow."
- <The Tale of the Black Forest>
- "Once upon a time, three happy birds lived in a warm and lush forest. The birds had no names, though the creatures of the forest would call them Big Bird, Long Bird, and Small Bird. Everyone lived freely and happily together in the peaceful forest. The birds wanted the forest to be safe more than anyone else, that way creatures from the outside could visit and have fun.
- It was a warm and sunny afternoon when a stranger visited the peaceful forest. He was a traveler, pioneer, and prophet, but at the same time, he was a nobody. He wanted to enter the forest, but the birds found him suspicious, so they didn't let him in.
- The stranger, angered, told the birds as he left: “Soon, a tragedy will befall the forest. It will be tainted with misdeeds and evil, and there will be constant conflict. The tragedies will only stop when a terrible beast appears and devours everything. The sun and moon will shine upon the forest no longer; the forest will never go back to what it was before.”
- The birds worried about the prophecy. What if conflicts really break out and a beast shows up to harm the forest just like the man said? That's when the birds decided to become the guardians of the forest. They loved this forest more than anyone else did, so they wanted to protect the creatures living in the forest and keep the peace.
- Big Bird, with its many eyes, decided to watch over the forest for intruders. For Big Bird's eyes could see very far, and see things we cannot see.
- Then somebody said, “But what if the beast shows up in the middle of the night, when the sky is dark and everyone is asleep?”
- Worried, Big Bird burned all of its feathers to make an everlasting lamp. Now the creatures of the forest were under Big Bird's constant watch, day and night.
- To keep the forest's peace, Long Bird weighed the sins of those who entered the forest. For Long Bird's scale was fair and just, and could weigh any and all kinds of sin.
- Then somebody said, “But what if the scale doesn't tip in either direction someday?”
- Worried, Long Bird made a scale that always tipped to one side. That way every judgement would yield a clear verdict.
- Small Bird decided to punish the creatures' wrongdoings with its beak.
- Then somebody said, “But your beak is so small, no one would find it hurtful.”
- Worried, Small Bird tore its mouth wide so it could swallow any creature in one bite.
- No one could visit the forest anymore, and bad rumors about the forest began to spread outside.
- “I heard terrible things happen to any creature that enters the forest.”
- “The Big Bird is always watching the creatures of the forest, there's no freedom.”
- “The Long Bird's scale isn't fair at all.”
- “The Small Bird's punishment is so scary.”
- The birds got upset.
- “We work so hard to protect the forest; why doesn't anyone appreciate our effort?”
- Fewer and fewer visitors came to the forest, more and more creatures were complaining, fights broke out daily, and yet the birds continued to work even harder to make the forest peaceful again, but...
- “No, this forest is so vast and wide, the three of us aren't enough to protect all of it.”
- “But there is no creature to protect this forest but us.”
- “If we combined our power, we could be stronger.”
The day when Big Bird's eyes that could see hundreds of kilometers away, Long Bird who could judge any sin, and Small Bird's mouth that could devour everything united into one, darkness fell upon the forest. Creatures screamed in terror and fear at the sight of the bird, and the forest soon fell into mayhem.- Then, in the middle of all the chaotic cries, someone shouted: “It's the beast! A big, scary monster lives in the black, dusky forest!”
The beast is here? The three birds, now as one, looked around but there was no one to be seen. The bird began to prowl the forest, looking for the beast. The forest would be in trouble if the beast really showed up.- But there was nothing. There were no creatures, no sun and moon, and no beast. All that was left was just a bird and the Black Forest. Since then, there were only nights dark as pitch.
- Rumor says there is a terrible beast in the Black Forest where no one lives."
- <Survivor Testimony>
- "Every single light in the facility went crazy. They kept flickering and flickering. I couldn’t even use my lighter. Then, this warm light shone through it all. It looked like a waning twilight, or a growing sunrise. Though, as we all know, sunlight can’t make its way into our facility.
- Everyone silently gazed at the light. Sudden darkness and a weird ray of light were enough reason to be frightened. It was scarier than anything gorey we’d seen here. It was a true fear of the unknown itself… (Omitted)
- …Something from afar was coming our way. Incandescent lights like stars from outer space were marching towards us. It looked like Big Bird’s eyes, but it wasn’t that Abnormality. I could hear these long arms scratching the floor.
- Someone broke the silence with a whisper: “That guy over there couldn’t run away in time...”
There was an employee kneeling on the floor; perhaps he couldn’t sense the danger approaching behind him, and once he noticed, it was too late. He couldn’t even scream. - Nobody would have been able to then. He just meaninglessly struggled to move his legs, desperate to run from the beast. There was no heroic act of someone standing up against the monster, not even a yell to warn him. Everyone was just watching him, waiting for the terrible thing that was about to happen.
- Each step sent a tremor through the whole facility. The monster was moving with such slow steps, but it seemed so fast. In the blink of an eye, it devoured the nameless employee in one bite, and right after that everyone started screaming in chaos. I had gone through handling countless suppressions, but that day, for the first time, I regretted ever joining the company.
- I was certain I wouldn’t get out of there alive. This helplessness overwhelmed me. I couldn’t even think about fighting back against the monster, and many others were feeling the same. I think I’m the only one who stayed sane enough to write this among all the survivors.
- The company will never tell our newbies about the existence of that monster. However, I wanted to leave them a warning at the very least. That’s why I’m writing this."
Trivia
- Apocalypse Bird received a rework before its re-introduction to the new version after Legacy, with the appearance of its eggs and its portrait getting redesigned.
- Apocalypse Bird is the first Abnormality that only appears for a specific event, and is also one of the first fusion Abnormalities.
- In the encyclopedia entries, in the "Testimony of a Survivor", is said that Apocalypse Bird was walking towards them, but in-game, Apocalypse Bird teleports through the facility instead.
- Certain details in Apocalypse Bird's encyclopedia entry, such as work preferences and the amount of PE-boxes it's said to produce, seem to come from Fragment of the Universe, due to it being a 'placeholder' Abnormality.
- Completing Apocalypse Bird's event instantly clears Gebura's "Proving Power" mission (since suppressing its eggs counts as suppressing three different ALEPH-class abnormalities).
- Apocalypse Bird has the highest amount of HP in the game, at 330,000 HP, which is far greater then that of Last Helix , which sports 22,000 HP.
