A female Diablos whose body turns black in the breeding season. It becomes extremely aggressive.

How the guidebook says to hunt it

It adds a charge that curves toward the hunter
A female Diablos whose shell has turned black as it enters the breeding season. Its hitzones are the same as the normal species', but it has more kinds of surprise attacks from underground and charges, and it is even more vicious. Blademasters, who fight at close range, can prepare the same way as for Diablos, but gunners will feel safer with the Evade Extender or Evasion +X skill.

Tips
It has wind pressure (large) and a roar (large) that can stun
Its softest part is the belly for cutting and impact, and the tail for shots
Its charge from mid range curves to follow the hunter's movement
Unless it is enraged, a Sonic Bomb makes it flinch while it is underground, and this lowers its stamina

Brackets after the damage give its element or status. Damage is the health the hunter loses. Guard break is how hard the attack pushes through a guard, and stun is how much it builds toward stunning the hunter. Stamina use is what the attack costs the monster. The levels are Low, Mid, and High; - means none.
