Fatalis is a traditional black dragon, with a long, serpentine neck and tail, along with a pair of large, yet muscular wings. Its body is covered in rigid black scales and lined with white spines along its back. Its head features four backwards-facing horns and rows of enlarged teeth, and fin-like ears. Like many other monsters, Fatalis has a pale underbelly, and like most other Elder Dragons, it possesses six limbs. Its forelimbs are surprisingly thin, belying immense strength.
Fatalis is an extremely powerful monster, able to wipe out entire hunting parties with relative ease. Its primary weaponry lies in its flame breath, fabled to have reduced a kingdom to ashes within a single night, which can be utilized to produce either a stream of fire or explosive projectiles. Fatalis is also able to release a cloud of flammable dust and set it alight, similar to Teostra, and it is known to use its whip-like tail and powerful, bone-crushing jaws to defend itself from nearby attackers.
Interestingly, the massive Black Blade located within a cave in Pokke Village has been noted to regenerate after Fatalis materials are mined from it.
Not much is known about Fatalis' habits, other then that it is extremely hostile to all living creatures—especially humans.
Fatalis has only been observed at the ruins of Castle Schrade, and the natural environment from whence it came is completely unknown.
Apart from a few key differences, it has six horns instead of the Fatalis's four horns, and the chest now is glowing faint blue, which is possibly the new element Black Flame. It utilizes new and unique attacks.
Fatalis is taken from "fata", Latin for destiny, or fate. Its Japanese name is "Miraboreas" (ミラボレアス), which might possibly come from Moirai and Boreas.
Fatalis' Japanese name has also been romanized as "Milla Boreis"
Fatalis is immune to any traps or hand thrown bombs (Flash Bombs, Sonic Bombs, etc.), although Barrel Bombs affect it, and it can be put to sleep, paralyzed or poisoned.
If enough damage is done to Fatalis it will be enraged until it dies.
When it's doing its Snap and Drag attack getting into contact with ANY of its body parts (including the long tail) will result in high damage/death.
Shooting it with the Ballista, cannon, or any other projectile when it is flying can cause it to fall.
The face/head is the weakest part of Fatalis.
One can lure the Fatalis to move towards the courtyard by ground instead of air, which will then cause the gate to fall on it, inflicting damage and giving hunters some time to attack fiercely.
It will flee three times (after or on 25 min. for each quest) and the fourth time is often the killing quest.
Fatalis can be carved nine times, 3 times on the lower body, 3 times on the upper body and 3 times on the head.
Fatalis' roar requires HG Earplugs to block.

Monster Hunter 4 Ultimate
Fatalis is unlocked upon reaching HR70.
Fatalis is fought in front of the gate of Castle Schrade.
Fatalis has two new attacks reminiscent of the fire dragons Teostra and Lunastra. It now has a flame breath attack with extended range compared to the fire dragons'. It also can release reactive powder around its general vicinity and ignite it, causing a large explosion to occur.
It also has an attack similar to Dire Miralis, in which it releases a powerful fireball in front of it that explodes on impact.
Fatalis' health has been reduced from previous iterations, and no longer carries over between hunts.
Fatalis will still flee after a certain threshold of time and damage is surpassed.
When Fatalis is performing its signature Snap and Drag attack, it will no longer deal full damage with every part of its body; touching its tail or hind legs will still knock you back, but will only deal minor damage.
Fatalis gains a sweeping bite that inflicts Dragonblight. It only uses it against hunters standing on the Dragonator platform.
Fatalis' head may be mounted in the manner of most other monsters backs.
Monster Hunter Generations
Although Fatalis is not in this game, you can craft its weapons and armor by mining the Giant Sword in Pokke Village.
Monster Hunter World: Iceborne
Fatalis was permanently added to the game on October 1, 2020 (UTC).
Fatalis has two different flinch shot interactions.
If it is standing on hindlegs or flying, the flinch shot it will force it to enter crawling stance, as well as dealing small amounts of damage.
If it is crawling, it will be thrown normally like other monsters, and be dealt heavy damage if successfully launched into a wall.
However, similar to Kulve Taroth and Shara Ishvalda, launching Fatalis into a wall will only stagger it.
Fatalis gains a new form during the final phase, in which its chest glows brightly and its breath attacks become incredibly powerful, capable of knocking out hunters easily.
Fatalis' head can be broken twice, which reduces the power of its breath attacks during the final phase for each break. Breaking Fatalis head will leave it laying still on the floor for several seconds.
Fatalis also gains a pin attack during the final phase.
Its fire breath will also leave patches of burning ground which deal damage over time to nearby hunters.
Fatalis gains a massive flame breath called "Schrade's Demise", which starts as small continuous chipping damage followed by a powerful wave that instantly knocks out any hunters caught within it. Hunters have to take cover to survive. The cover changes spots for each phase. Fatalis performs the flame attack when its health has reached a certain threshold;
End of phase 1: Behind a metal plating to the right side of the arena. Fatalis has 80% HP left.
End of phase 2 : Behind a metal barricade that has to be manually raised behind the dragonators. Fatalis has 50% HP left.
Final phase: Under the Fatalis itself. Fatalis performs the attack three times in this phase. The first when it has 40% HP left, the second one at 20%, and the third and final one when it has 5% HP left.
It is possible to kill Fatalis before it initiates the final flame breath by disabling the Black Dragon for a long enough time.
Fatalis body now yield 6 carves, and can only be carved from one carving spot.
After hitting Fatalis with the Dragonator, the original version of Proof of a Hero will play. This is a callback to the First Generation, where Fatalis was introduced.
Plus, after slaying Fatalis, the first Monster Hunter victory theme (Triumph!) will play.
