Fatalis is a traditional black dragon, with a long, serpentine neck and tail, along with a pair of large wings. Its body is covered in rigid black scales and lined with white spines. Its head features four backwards-facing horns and a row of enlarged bottom teeth.
Fatalis is an extremely powerful monster, able to wipe out entire hunting parties with relative ease. Its primary means of defence is its ability to breathe a stream of fire and launch flaming projectiles, which explode upon impact. It is also able to release a cloud of flammable dust, similar to Teostra, and set it alight. It is known to use its whip-like tail to batter enemies, and its powerful bone crushing jaws to bite at nearby attackers.
Fatalis 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 original name in Japanese version is Mirabilis, which is Latin for miraculous.
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.

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.
