Vis Infernalus

Vis Infernalus is an Elder Dragon appearing in Monster Hunter Frontier: Old World.

Description
A Dragon with a body similar to the Fatalis family, it has black scales and red hair covering parts of its body, when enraged, all the hair patches will stand up and Energy element electricity will cover the monster.

It has a crest similar to that of a Velocidrome but red in color, when broken, its Energy powers are weakened.

This monster is at the power level of Crimson Fatalis and was mistaken for a Fatalis family member at first, it can launch beams, balls and breath energy, it can cover itself in it, shoot an Energy Laser from its mouth like a Gravios and generate a big Energy Explosion around itself.

The Special Rank HC is much bigger, becoming a Conquest War monster, it has far more power than the normal one and has more prominent hair, also, the red Energy becomes black.

It was recognised by an ancient civilization as "Bad Heaven", the representation of a bad place where the bad people go, it has also been called the "West Land Fatalis" and "Shantien's Nemesis".

Attacks
Common energy attacks include beams, balls, lasers, breath, pillars and proximity traps.

Other attacks include:

Supernova: Performs a powerful roar which creates a ball of energy in its mouth, while roaring the ball will grow at significant speed and create a big Energy explosion with high splash damage.

Super Rage: Only performed when already in rage, this counts as a Secondary Rage, it will growl and extra body parts made out of Energy will apear around its body, increasing offensive and defensive power.

Overdrive Supernova: A powerful version of the supernova, done rarely while in Super Rage, or commonly by the HC version.

Final Rage: When Vis Infernalus is about to die (last 15% of health is left), the Super Rage will randomly disappear and Vis Infernalus will "Play Dead", after some seconds, its eyes will start glowing with energy and the fight will resume, Vis Infernalus is now covered in even more Energy Armor, becomes faster and more powerful, is locked in rage and has a much higher chance of abusing the Overdrive Supernova.
