Firepower Black Gravios

Fiery Nightmare Black Gravios are Deviants of Black Gravios.

Explanation
An old Black Gravios that has never wandered outside the fire of the Volcanoes. Being in extreme heat all the time it has become completely unstable from its body temperature and must vent this heat non stop.

Story Behind Its Secondary Name
Miners from the Volcano reported seeing a Gravios with a jet black shell, with only the orange glow from its eyes and vents being the only way they could see it from the volcanoes ashes. They described the monster as a Fiery Nightmare and with research the Hunters Guild declared it to be a special variant and due to the warnings of the power it has only ones with special tickets can fight it.

Aesthetic Differences
Jet black shell. Spiked clumps of hardened lava across its head, back, wings, legs, chest, back and tail. Orange glowing eyes, spines and the shell crevices across its body. Ends of spines turned to vents. Back plates expanded out and shaped into spikes. Voice and roars sound more like steam.

Attacks
It has all the attacks the MH4U G Rank Black Gravios can use, even when not enraged.

Level 1 - 5

 * Armor of lava: Like the Agnaktor it has pieces of hardened lava on its body that reflect attacks. Lava and fire gas will soften the armor which gives chances to break it off.
 * Fire gas expelling overload: Until the back is broken completely it will use a fire expel after completing almost every single attack, even the tail spin. After the back is completely broken the fire expels change to how a regular Black Gravios uses them but cannot be stopped completely.
 * Beams cause more fire gas: The radius on its fire gas after a beam is double the size of normal ones. Plus the expel is done almost immediately the beam stops.
 * Continuous fire gas expel: While using its charge or the fire blast shooting walk it will use gas in a continuous stream instead of a single quick burst.
 * Surrounded by fire gas: When it does its attack when it does it releases fire gas directly as an attack it will surround its entire body due to vents around its entire body. Its effectiveness lowers as vents are broken,
 * Triple fire gas expel: A attack borrowed from Basarios which it will do three fire gas expels in a row which will be double in size than normal ones.
 * Bite bullet: When it does its usually harmless side bite it will shoot a fire blast from its mouth that extends the range and damage of the attack.
 * Blast gas: Because the insides of this Deviant are too hot to contain sleep ailments the sleep organs have mutated into gas which contains combustible substances. Basically this replaces the sleep gas attack with Blastblight.

(When enraged)
 * Explosive landing: An alteration to its jump attack. When it jumps up it will unleash Blastblight gas on the ground and take off. When it crashes down its fire gas will ignite the other gas and cause a wide explosion.
 * Triple fire beam: Will do its fire beam three times in a row.
 * Fire blasts on fire blasts: Its rapid fire blasts will explode upon hitting the ground instead of just disappearing.

Level 6 - 10

 * Speedy beams: All of its beam attacks are charged up 2 times their original speed.
 * Tail blast: Its tail will expel blast gas and then is slammed down for an explosion. This attack is rather dangerous due to its speed. Effectiveness is lost when tail is wounded and cannot be used when tail is severed.
 * Double tail blast: The above attack is done to its right and left in even faster succession.
 * Leg blast: Now when its hipcheck is done with the legs not wounded a small explosion will occur in the attack radius.

(When enraged)
 * Hyper beam: In an attack borrowed from the HC Gravios from frontier it will raise its head as a bright flash forms in its mouth. It will then quickly swing its head around and a gigantic beam will be fired with massive range ending in a burst of blast powder from the mouth. This attack can one hit kill a hunter if their right next to the FNBGravios.
 * Explosive firepower: All its intact vents will release blast powder all around it as fire begins to charge in its mouth. With a bite it ignites the powder which causes fire gas to be expelled, sending a wave of fire to be sent around it. Some of this fire is sucked into its mouth turning the flame furious. It will stand upwards as the fire turns a blinding white and once it reaches larger than the size of FNBGravios' head it is shot at the ground at a distance in a blazing beam. As soon as it hits the ground a eruption of fire will emerge in the area in which the beam is being shot at. To end it all off a huge fire blast is fired into the eruption and makes the whole thing blast into a huge explosion. But it doesn't end there... Four fire blasts of large size erupt from the explosion into the air and fall to the ground and add four more explosions to the already huge one. Hunters with bad fire resistance are completely doomed.
